Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies [Text Block]	Basis of presentation and significant accounting policies (a) Basis of Presentation Basis of Presentation – The accompanying condensed unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. The details of subsidiaries are disclosed in Note 1. Significant inter-company balances and transactions have been eliminated upon consolidation. The condensed unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions in Article 10 of Regulation S-X. Accordingly they do not include all of the information and footnotes required by such accounting principles for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The accompanying interim condensed consolidated financial statements are unaudited, but in the opinion of the Company’s management, contain all necessary adjustments, which include normal recurring adjustments, for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2017 is derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Certain information and footnote disclosures normally included in financial statements that have been prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although the Company’s management believes that the disclosures contained in these financial statements are adequate to make the information presented herein not misleading. For further information, please refer to the financial statements and the notes thereto included in the Company’s 2017 Annual Report on Form 10-K, as filed with the Securities and Exchange Commission. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2018. Estimation - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Foreign Currencies - China Automotive, the parent company, and HLUSA maintain their books and records in United States Dollars, “USD,” their functional currency. The Company’s subsidiaries based in the PRC and Genesis maintain their books and records in Renminbi, “RMB,” their functional currency. The Company’s subsidiary based in Brazil maintains its books and records in Brazilian reais, “BRL,” its functional currency. In accordance with ASC Topic 830, “FASB Accounting Standards Codification”, foreign currency transactions denominated in currencies other than the functional currency are remeasured into the functional currency at the rate of exchange prevailing at the balance sheet date for monetary items. Nonmonetary items are remeasured at historical rates. Income and expenses are remeasured at the rate in effect on the transaction dates. Transaction gains and losses, if any, are included in the determination of net income for the period. Recent Accounting Pronouncements In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, to address specific consequences of the recent U.S. federal tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “U.S. Tax Reform”). The update allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Reform. The accounting update is effective January 1, 2019, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the U.S. Tax Reform is recognized. The Company is currently evaluating the impact of the new standard on the Company's consolidated financial statements. (c) Significant Accounting Policies Net Product Sales - On January 1, 2018, the Company adopted ASC Topic 606 “Revenue from Contracts with Customers”, and all related amendments, using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting practices under ASC Topic 605 “Revenue Recognition”. Management has determined that the impact of the transition to the new standard is immaterial to the Company’s revenue recognition model since the vast majority of our revenue recognition is based on point in time transfer of control. Accordingly, the Company has not made any adjustment to opening retained earnings. Products sales to customers are made pursuant to master agreements entered into between the Company and its customers that provide for transfer of both title and risk of loss upon the Company’s delivery to the location specified in the contracts. The Company’s sales arrangements generally do not contain variable considerations and short-term in nature. A period of credit term is granted to the customers after the delivery and before making payment. The Company recognizes revenue at a point in time based on management’s evaluation of when the customer obtains control of the products. Revenue is recognized when all performance obligations under the terms of a contract with the customer are satisfied and control of the product has been transferred to the customer. Sales of goods typically do not include multiple product and/or service elements. Revenue is measured as the amount of consideration management expects the Company to receive in exchange for transferring goods pursuant to the contracts. Value-added tax that the Company collects concurrent with revenue-producing activities is excluded from revenue. Incidental contract costs that are not material in the context of the delivery of goods and services are recognized as expense. At the time revenue is recognized, allowances are recorded, with the related reduction to revenue, for estimated price discounts based upon historical experience and related terms of customer arrangements. Where the Company has offered product warranties, the Company also establishes liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liabilities are adjusted when experience indicates the expected outcome will differ from initial estimates of the liability. The Company treats shipping and handling fees as a fulfillment cost since control of the products is usually transferred to the customer after the delivery. Revenue Disaggregation Management has concluded that the disaggregation level is the same under both the revenue standard and the segment reporting standard. Revenue under the segment reporting standard is measured on the same basis as under the revenue standard, so management did not repeat the disaggregation of revenue under both standards. Contract Assets and Liabilities Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of the Company’s revenue recognition process. The majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory, fixed assets and intangible assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of our products and their respective manufacturing processes. Contract liabilities are mainly customer deposits. Customer Deposits As of March 31, 2018, the Company has customer deposits of $ 1.4 1.3 1.0 Practical Expedient and Exemptions The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The Company does not adjust the promised amount of consideration for the effects of a significant financing component since the Company expects, at contract inception, that the period between when the Company transfers promised goods to the customers and when the customers pay for the goods will be within one year. Except for the adoption of ASC Topic 606, there have been no updates to the significant accounting policies set forth in the notes to the consolidated financial statements for the year ended December 31, 2017.

Short Term Investments Disclosure [Abstract]
Short Term Investments Disclosure [Text Block]	Short-term investments Short-term investments comprise time deposits with terms of three months or more which are due within one year and financial instruments with a variable interest rate indexed to the performance of underlying assets (“Wealth Management Financial Products”) with maturities within one year. The carrying values of time deposits approximate fair value because of their short maturities. The interest earned is recognized in the consolidated statements of income over the contractual term of the deposits. The Wealth Management Financial Products are measured at fair value and classified as Level 2 within the fair value measurement hierarchy. The fair values were measured by using directly or indirectly observable inputs in the marketplace. Changes in the fair value are reflected in other income in the consolidated statements of operations and comprehensive income.

Significant concentrations

Risks and Uncertainties [Abstract]
Concentration Risk Disclosure [Text Block]	25. Significant concentrations A significant portion of the Company’s business is conducted in China where the currency is the RMB. Regulations in China permit foreign owned entities to freely convert the RMB into foreign currency for transactions that fall under the "current account," which includes trade related receipts and payments, interest and dividends. Accordingly, the Company’s Chinese subsidiaries may use RMB to purchase foreign exchange for settlement of such "current account" transactions without pre-approval. However, pursuant to applicable regulations, foreign-invested enterprises in China may pay dividends only out of their accumulated profits, if any, determined in accordance with the PRC law. In calculating accumulated profits, foreign investment enterprises in China are required to allocate at least 10 50 Transactions other than those that fall under the "current account" and that involve conversion of RMB into foreign currency are classified as "capital account" transactions; examples of "capital account" transactions include repatriations of investment by or loans to foreign owners, or direct equity investments in a foreign entity by a China domiciled entity. "Capital account" transactions require prior approval from China's State Administration of Foreign Exchange, or SAFE, or its provincial branch to convert a remittance into a foreign currency, such as USD, and transmit the foreign currency outside of China. This system could be changed at any time and any such change may affect the ability of the Company or its subsidiaries in China to repatriate capital or profits, if any, outside China. Furthermore, SAFE has a significant degree of administrative discretion in implementing the laws and has used this discretion to limit convertibility of current account payments out of China. Whether as a result of a deterioration in the Chinese balance of payments, a shift in the Chinese macroeconomic prospects or any number of other reasons, China could impose additional restrictions on capital remittances abroad. As a result of these and other restrictions under the laws and regulations of the PRC, the Company’s PRC subsidiaries are restricted in their ability to transfer a portion of their net assets to the parent. The Company has no assurance that the relevant Chinese governmental authorities in the future will not limit further or eliminate the ability of the Company’s PRC subsidiaries to purchase foreign currencies and transfer such funds to the Company to meet its liquidity or other business needs. Any inability to access funds in China, if and when needed for use by the Company outside of China, could have a material and adverse effect on the Company’s liquidity and its business. During the three months ended March 31, 2018, the Company’s five largest customers accounted for 41.9 10 18.9 4.8 10 During the three months ended March 31, 2017, the Company’s five largest customers accounted for 40.4% of its consolidated net product sales, with one customer individually accounting for more than 10% of consolidated net sales i.e., 12.9%. As of March 31, 2017, approximately 5.1% of accounts receivable were from trade transactions with the aforementioned customer and there was no individual customer with a receivables balance of more than 10% of total accounts receivable.

Segment Reporting [Abstract]
Segment Reporting Disclosure [Text Block]	30. Segment reporting The accounting policies of the product sectors are the same as those described in the summary of significant accounting policies except that the disaggregated financial results for the product sectors have been prepared using a management approach, which is consistent with the basis and manner in which management internally disaggregates financial information for the purposes of assisting them in making internal operating decisions. Generally, the Company evaluates performance based on stand-alone product sector operating income and accounts for inter segment sales and transfers as if the sales or transfers were to third parties, at current market prices. As of March 31, 2018, the Company had 12 product sectors, five of which were principal profit makers and were reported as separate sectors and engaged in the production and sales of power steering (Henglong, Jiulong, Shenyang, Wuhu and Hubei Henglong), and one holding company (Genesis). The other seven sectors were engaged in the production and sale of sensor modular (USAI), automobile steering columns (Jielong), provision of after sales and R&D services (HLUSA), production and sale of power steering (Chongqing Henglong), trade (Brazil Henglong), manufacture and sales of automobile electronic systems and parts (Wuhan Chuguanjie) and research and development of intelligent 10 As of March 31, 2017, the Company had 11 product sectors, five of which were principal profit makers and were reported as separate sectors and engaged in the production and sales of power steering (Henglong, Jiulong, Shenyang, Wuhu and Hubei Henglong), and one holding company (Genesis). The other six sectors were engaged in the production and sale of sensor modular (USAI), automobile steering columns (Jielong), provision of after sales and R&D services (HLUSA), production and sale of power steering (Chongqing Henglong), trade (Brazil Henglong), and manufacture and sales of automobile electronic systems and parts (Wuhan Chuguanjie).

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	(a) Basis of Presentation Basis of Presentation – The accompanying condensed unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. The details of subsidiaries are disclosed in Note 1. Significant inter-company balances and transactions have been eliminated upon consolidation. The condensed unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions in Article 10 of Regulation S-X. Accordingly they do not include all of the information and footnotes required by such accounting principles for complete financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017. The accompanying interim condensed consolidated financial statements are unaudited, but in the opinion of the Company’s management, contain all necessary adjustments, which include normal recurring adjustments, for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. The condensed consolidated balance sheet as of December 31, 2017 is derived from the Company’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. Certain information and footnote disclosures normally included in financial statements that have been prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission, although the Company’s management believes that the disclosures contained in these financial statements are adequate to make the information presented herein not misleading. For further information, please refer to the financial statements and the notes thereto included in the Company’s 2017 Annual Report on Form 10-K, as filed with the Securities and Exchange Commission. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2018. Estimation - The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Foreign Currencies - China Automotive, the parent company, and HLUSA maintain their books and records in United States Dollars, “USD,” their functional currency. The Company’s subsidiaries based in the PRC and Genesis maintain their books and records in Renminbi, “RMB,” their functional currency. The Company’s subsidiary based in Brazil maintains its books and records in Brazilian reais, “BRL,” its functional currency. In accordance with ASC Topic 830, “FASB Accounting Standards Codification”, foreign currency transactions denominated in currencies other than the functional currency are remeasured into the functional currency at the rate of exchange prevailing at the balance sheet date for monetary items. Nonmonetary items are remeasured at historical rates. Income and expenses are remeasured at the rate in effect on the transaction dates. Transaction gains and losses, if any, are included in the determination of net income for the period.
New Accounting Pronouncements, Policy [Policy Text Block]	(b) Recent Accounting Pronouncements In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, to address specific consequences of the recent U.S. federal tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “U.S. Tax Reform”). The update allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the U.S. Tax Reform. The accounting update is effective January 1, 2019, with early adoption permitted, and is to be applied either in the period of adoption or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the U.S. Tax Reform is recognized. The Company is currently evaluating the impact of the new standard on the Company's consolidated financial statements.
Significant Accounting Policies [Policy Text Block]	(c) Significant Accounting Policies Net Product Sales - On January 1, 2018, the Company adopted ASC Topic 606 “Revenue from Contracts with Customers”, and all related amendments, using the modified retrospective method applied to those contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting practices under ASC Topic 605 “Revenue Recognition”. Management has determined that the impact of the transition to the new standard is immaterial to the Company’s revenue recognition model since the vast majority of our revenue recognition is based on point in time transfer of control. Accordingly, the Company has not made any adjustment to opening retained earnings. Products sales to customers are made pursuant to master agreements entered into between the Company and its customers that provide for transfer of both title and risk of loss upon the Company’s delivery to the location specified in the contracts. The Company’s sales arrangements generally do not contain variable considerations and short-term in nature. A period of credit term is granted to the customers after the delivery and before making payment. The Company recognizes revenue at a point in time based on management’s evaluation of when the customer obtains control of the products. Revenue is recognized when all performance obligations under the terms of a contract with the customer are satisfied and control of the product has been transferred to the customer. Sales of goods typically do not include multiple product and/or service elements. Revenue is measured as the amount of consideration management expects the Company to receive in exchange for transferring goods pursuant to the contracts. Value-added tax that the Company collects concurrent with revenue-producing activities is excluded from revenue. Incidental contract costs that are not material in the context of the delivery of goods and services are recognized as expense. At the time revenue is recognized, allowances are recorded, with the related reduction to revenue, for estimated price discounts based upon historical experience and related terms of customer arrangements. Where the Company has offered product warranties, the Company also establishes liabilities for estimated warranty costs based upon historical experience and specific warranty provisions. Warranty liabilities are adjusted when experience indicates the expected outcome will differ from initial estimates of the liability. The Company treats shipping and handling fees as a fulfillment cost since control of the products is usually transferred to the customer after the delivery. Revenue Disaggregation Management has concluded that the disaggregation level is the same under both the revenue standard and the segment reporting standard. Revenue under the segment reporting standard is measured on the same basis as under the revenue standard, so management did not repeat the disaggregation of revenue under both standards. Contract Assets and Liabilities Contract assets, such as costs to obtain or fulfill contracts, are an insignificant component of the Company’s revenue recognition process. The majority of the Company’s cost of fulfillment as a manufacturer of products is classified as inventory, fixed assets and intangible assets, which are accounted for under the respective guidance for those asset types. Other costs of contract fulfillment are immaterial due to the nature of our products and their respective manufacturing processes. Contract liabilities are mainly customer deposits. Customer Deposits As of March 31, 2018, the Company has customer deposits of $ 1.4 1.3 1.0 Practical Expedient and Exemptions The Company does not disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. The Company does not adjust the promised amount of consideration for the effects of a significant financing component since the Company expects, at contract inception, that the period between when the Company transfers promised goods to the customers and when the customers pay for the goods will be within one year. Except for the adoption of ASC Topic 606, there have been no updates to the significant accounting policies set forth in the notes to the consolidated financial statements for the year ended December 31, 2017.

[1]	In May 2017, the Company obtained an additional 15.84% equity interest in Brazil Henglong for nil consideration. The Company retained its controlling interest in Brazil Henglong and the acquisition of the non-controlling interest was accounted for as an equity transaction.
[2]	On August 16, 2017, the Company granted 22,500 stock options to the Company’s independent directors, with the exercise price equal to the closing price of the Company’s common stock traded on NASDAQ one day before the date of grant and on the date of grant. The fair value of the stock options was determined at the date of grant using the Black-Scholes option pricing model. The Black-Scholes option model requires management to make various estimates and assumptions, including expected term, expected volatility, risk-free rate and dividend yield. The expected term represents the period of time that stock-based compensation awards granted are expected to be outstanding and is estimated based on considerations including the vesting period, contractual term and anticipated employee exercise patterns. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free rate is based on the U.S. Treasury yield curve in relation to the contractual life of stock-based compensation instruments. The dividend yield assumption is based on historical patterns and future expectations for the Company’s dividends.
