PART III — NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR or the transition report or portion thereof, could not be filed within the prescribed time period.

     Although management of China Yuchai International Limited (“CYI”) has been working to complete all the required information for its annual report on Form 20-F for the fiscal year ended December 31, 2005 (the “Form 20-F”), and a substantial part of such information has been completed as of this date, the Form 20-F could not be completed on or before the June 30, 2006 prescribed due date. As a result of the recent investment activities undertaken by CYI pursuant to its business and diversification expansion plan, as disclosed in CYI’s Form 6-Ks submitted with the U.S. Securities and Exchange Commission on January 26, 2006, February 3, 2006, February 28, 2006, March 1, 2006 and April 5, 2006, management has been required to devote additional time and resources to finalize its audited financial statements and related disclosure, as well as attend to many related internal matters, such that it was not possible for management to complete the Form 20-F by the June 30, 2006 prescribed due date without unreasonable effort or expense. In addition, as a result of the above, CYI’s accountants were not able to complete their review of the Form 20-F in time for filing by the June 30, 2006 prescribed due date. Management anticipates filing the
Form 20-F on or before July 15, 2006.
