This Amendment No. 6 to Schedule 13D (this “Amendment No. 6”) is filed with respect to China Grentech Corporation Limited (the “Company” or “Issuer”) jointly by Guoren Industrial Developments Limited (“Guoren Industrial”), Heng Xing Yue Investments Limited (“HXY”), Mr. Yingjie Gao (“Mr. Gao”), Ce Lue Investments Limited (“Ce Lue”), Target Growth Holdings Limited (“Target Growth”) and Credit Suisse Trust Limited as Trustee of the GRRF Trust (“Trustee”). Guoren Industrial, HXY, Mr. Gao, Ce Lue, Target Growth and Trustee are collectively referred to herein as the “Reporting Persons.”

This Amendment No. 6 amends and supplements the a statement on Schedule 13D filed on February 12, 2008 on behalf of the reporting persons named therein with the United States Securities and Exchange Commission, as amended on September 9, 2008, January 19, 2010, October 18, 2011, November 15, 2011 and November 22, 2011 (as amended and supplemented to date, the “Schedule 13D”). Except as provided herein, this Amendment No. 6 does not modify any of the information previously reported on the Schedule 13D. Capitalized terms used but not defined herein have the meanings assigned to them in the Schedule 13D.

ITEM 4. PURPOSE OF TRANSACTION

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following at the end thereof:

On December 7, 2011, at the request of Mr. Gao, Trustee, on behalf of Target Growth, transferred one (1) fully-paid ordinary share with a par value of US$1.00 in Ce Lue, representing the entire issued and outstanding ordinary shares in Ce Lue, to Mr. Gao. Thereafter, Target Growth will be liquidated, followed by the termination of the GRRF Trust.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

(a) As of the date of this Amendment No. 6, each of Guoren Industrial and HXY beneficially owns, and is the record holder of, 149,188,825 and 34,006,550 ordinary shares in the issuer, respectively. By virtue of their membership of a group for purposes of the Schedule 13D, each of Ce Lue and Mr. Gao may be deemed to beneficially own such shares totaling 183,195,375 ordinary shares in the issuer, which represent approximately 32.5% of the issuer’s outstanding share capital as of the date of this Amendment No. 6. As a result of the transactions described in Item 4, as of December 7, 2011, neither Target Growth nor the GRRF Trust beneficially owns any ordinary share in the issuer.

(b) As of the date of this Amendment No. 6, by virtue of their membership of a group for purposes of the Schedule 13D, Guoren Industrial, HXY, Ce Lue and Mr. Gao may be deemed to have shared voting power to vote or direct the vote, and dispose or direct the disposition of all 183,195,375 ordinary shares in the issuer. As a result of the transactions described in Item 4, as of December 7, 2011, neither Target Growth nor the GRRF Trust has any voting or dispositive power over any ordinary share in the issuer.

(c) Except for the transactions described in Item 4, there were no transactions in the ordinary shares in the issuer effected by the Reporting Person during the past 60 days.

(e) As a result of the transactions described in Item 4, as of December 7, 2011 each of Target Growth and the GRRF Trust ceased to be the beneficial owner of more than five percent of the outstanding ordinary shares in the issuer.

Trustee disclaims beneficial ownership of the ordinary shares in the issuer. The filing of the Schedule 13D and this Amendment No. 6 should not be deemed an admission that Trustee is the beneficial owner of any ordinary share in the issuer for any purpose.
