attributable to increases in copper prices in 2021 and lower sales volumes in 2020 because of the COVID-19 pandemic. Revenue in the Company’s North Asia region increased by 46.2% to $107.0 million, primarily due to increases in copper prices in 2021 and lower sales volumes in 2020 because of the COVID-19 pandemic. Revenue in the Company’s ROW region increased by 77.7% to $171.8 million, primarily due to the deferral of orders from 2020 to 2021 and increased local sales in 2021 resulting from stricter border controls related to COVID-19. The Company’s North Asia region includes China and Hong Kong; the Thailand region consists of operations and sales within Thailand; and the ROW region includes Singapore, Australia and the other markets where APWC has operations or sales outside of the Thailand and North Asia regions.

Operating profit margin decreased from a profit of 2.4% in 2020 to a loss of 1.0% in 2021.

The operating profit in the North Asia region was not significantly affected by the copper price fluctuation. The ROW region’s operating profit margin increased from a loss of 4.6% in 2020 to a profit of 3.9% in 2021, primarily attributable to decreased competition from stricter border controls due to COVID-19.
