This Report on Form 6-K shall be deemed to be incorporated by reference in the
prospectus, dated March 24, 2004, of China Yuchai International Limited (the
"Company" or "CYI") included in the Company's Registration Statement
(Registration No. 333-111106) on Form F-3 and to be part thereof from the date
on which this report is filed, to the extent not superseded by documents or
reports subsequently filed or furnished by the Company with the U.S. Securities
and Exchange Commission (the "SEC").

The Company wishes to caution readers that the press release contains
forward-looking statements, as defined in the safe harbor provisions of the U.S.
Private Securities Litigation Reform Act of 1995. These forward-looking
statements, including without limitation, statements relating to the Company's
financial performance and growth prospects, are subject to certain risks and
uncertainties, which could cause actual results to differ materially from
historical results or those anticipated. Among the risks and factors that could
cause actual results to differ materially are: the Company's ability to control
Guangxi Yuchai Machinery Company Limited ("Yuchai"); the Company's ability to
consolidate Yuchai's financial results; changes in the capital markets and
interest rates; political, economic and social conditions in China such as
government policies with respect to foreign investment, economic growth,
inflation and the availability of credit; the effects of competition in the
diesel engine market; the effects of inflation; the ability of Yuchai to control
its expenses, capital expenditures and receivables, finance its working capital
and capital expenditures and commercially introduce new products in the future;
the Company's ability to successfully implement the agreement it reached with
Yuchai in July 2003 and the reorganization agreement of April 2005; the effects
of uncertainties in the Chinese legal system which could limit the legal
protections available to foreign investors, including with respect to the
enforcement of foreign judgments in China; and the effects of China becoming a
member of the World Trade Organization. Although the Company believes the
expectations reflected in such forward-looking statements are based upon
reasonable assumptions, the Company can give no assurance that its expectations
will be attained. In addition to the foregoing factors, a description of certain
other risks and uncertainties which could cause actual results to differ
materially can be found in the section captioned "Risk Factors" in the Company's
Annual Report on Form 20-F filed with the SEC under the Securities Exchange Act
of 1934, as amended. Readers are cautioned not to place undue reliance on these
forward-looking statements, which are based on the current view of management on
future events. The Company undertakes no obligation to publicly update or revise
any forward-looking statements, whether as a result of new information, future
events or otherwise.
