Exhibit 99.1

China Yuchai International’s reporting of selected unaudited fourth quarter and full year 2010
financial results

Singapore, Singapore – February 28, 2011 – China Yuchai International Limited (NYSE: CYD) (“China Yuchai” or the “Company”) announced today that although it has generally released detailed unaudited fourth quarter and full year financial results approximately two months following the end of such periods, it will not be able to do so until a later date with regard to the fourth quarter and full year ended December 31, 2010 as its main operating joint-venture subsidiary, Guangxi Yuchai Machinery Company Limited (“GYMCL”), has only very recently closed its financial accounts for fiscal year 2010 which has lengthened the financial reporting process.

China Yuchai is therefore able to release at this time only selected unaudited consolidated financial data for the full year ended December 31, 2010 and the fourth quarter of 2010.

Net revenues for the fourth quarter of 2010 were RMB 4.0 billion (US$ 606.5 million) compared with RMB 3.2 billion (US$ 490.6 million) in the fourth quarter of 2009. The total number of diesel engines sold during the fourth quarter of 2010 increased to 115,460 from 101,363 units in the fourth quarter of 2009, and from 109,023 units during the third quarter of 2010.

Net revenues for fiscal 2010 increased 24.7% to RMB 16.4 billion (US$ 2.5 billion) from RMB 13.2 billion (US$ 2.0 billion) in 2009. The total number of diesel engines sold in 2010 was 551,592 units, a 17.9% increase compared with 467,899 units sold in 2009. The increase in net revenues was a result of greater unit volume across the board and better sales mix.

Net income attributable to China Yuchai shareholders increased 79.9% to RMB 1.13 billion, (US$ 170.6 million) in 2010 from RMB 628.3 million (US$ 94.9 million) in 2009.

The Company will report the detailed unaudited consolidated financial results for the fourth quarter and full year 2010 as soon as they are available which will be followed by an earnings call for the investment community.
