EXHIBIT 1.1 CHINA YUCHAI INTERNATIONAL LIMITED 16 RAFFLES QUAY #26-00 HONG LEONG BUILDING SINGAPORE 048581 TEL : (65) 6220 8411 FAX : (65) 6226 0502 FOR IMMEDIATE RELEASE CHINA YUCHAI INTERNATIONAL LIMITED ANNOUNCES GOOD PERFORMANCE FOR 2003 SINGAPORE, FEBRUARY 27, 2004 - China Yuchai International Limited ("CYI") today announced good performance for the year ended December 31, 2003. Net sales of Rmb4,569.9 million (US$552.1 million) for the year ended December 31, 2003 represents an increase of approximately 30% compared to the prior year of Rmb3,513.0 million (US$424.5 million). Total unit sales of 172,219 diesel engines for the year ended December 31, 2003 was 32% higher than during 2002. Continued buoyant demand for diesel engines in the China market and good customer acceptance of Yuchai's new 4 cylinder series and industrial models contributed to this growth. Net income of Rmb438.2 million (US$52.9 million) in 2003 increased 6% as compared to the net income of Rmb412.4 million (US$49.8 million) for 2002. The improvement in profit performance was constrained by Guangxi Yuchai Machinery Company Limited's ("Yuchai") limited production capacity for high margin, heavy-duty engines. Yuchai was unable to meet market demand for this growth category of engines in 2003. During 2002, Yuchai had grown its unit sales by 76% using up much of the plant's excess capacity. In April 2003, an additional 4 cylinder series light-duty engine production line was commissioned increasing capacity by 40,000 units per annum for this product series. Using this additional capacity, sales of 4 cylinder series, light-duty engines achieved growth of 108% with 40,275 diesel engines sold during 2003 as compared to 19,397 during the previous year. Sales of industrial engines including those for construction equipment reached 25,080 units for 2003 as compared to 11,328 engines sold during the previous year. Sales of high margin, medium-duty diesel engines were almost identical to the previous year. Sales of high margin, heavy-duty diesel engines were constrained by limited production capacity in 2003.

CHINA YUCHAI INTERNATIONAL LIMITED 16 RAFFLES QUAY #26-00 HONG LEONG BUILDING SINGAPORE 048581 TEL : (65) 6220 8411 FAX : (65) 6226 0502 The gross profit margins achieved for both the 4 cylinder series light-duty and the industrial engines were lower than margins historically achieved for both medium and heavy-duty engines. Thus, the overall gross profit margins of 30% is slightly lower when compared to the previous year of 33% because of these factors. For the year ended December 31, 2003, selling, general and administrative expenses increased by approximately 32% due mainly to higher staff costs, transport charges arising from higher unit sales, advertising costs, legal and professional fees relating to the legal and arbitration proceedings in respect of shareholder disputes and research and development expenditures. As a result, operating income increased to Rmb721.4 million (US$87.1 million) for 2003 as compared to Rmb640.3 million (US$77.4 million) for 2002. Interest cost declined slightly to Rmb23.6 million (US$2.9 million) for the year ended December 31, 2003 as compared to Rmb25.1 million (US$3.0 million) for 2002 due to the repayment of bank loans during the year. YUCHAI'S ENGINE UNIT SALES GROWTH OUT PERFORMS THE MARKET The growth pattern in China for diesel engine usage, established over the last few years, was reinforced in 2003. According to Government industry statistics, during 2003, there was an increase in the sales of trucks and buses in China of approximately 16% compared to 2002 (source data : China Association of Automobile Manufacturers). CYI believes Yuchai grew its market share and out performed its competitors by growing its unit sales 32% compared with 2002. A breakdown of sales according to size and horsepower range shows an even clearer picture of how CYI believes Yuchai is successfully adjusting its strategy to meet market demand and grow market share. (A) Sales of light duty (4 cylinder) engines for mini buses and small trucks continue to experience high growth in China. As previously mentioned, Yuchai sales of the new light duty engines grew 107%, benefiting from the additional light duty engine production capacity (40,000 units per year) commissioned in April 2003. While in 2003, the gross margin from light duty engines was much lower than Yuchai's traditional products, Yuchai has historically found that margins typically improve with time, as production processes are refined and costs reduced. (B) Sales of medium duty (6 cylinder, 140 - 200 Hp) engines for 5 to 7 tonne trucks and buses continued to decline in China. With the improvement in the high way system, transportation companies now find that these traditional sized vehicles are less economic than the newer larger units.

CHINA YUCHAI INTERNATIONAL LIMITED 16 RAFFLES QUAY #26-00 HONG LEONG BUILDING SINGAPORE 048581 TEL : (65) 6220 8411 FAX : (65) 6226 0502 Despite this trend, Yuchai's sales of medium duty engines increased 2% in 2003. (C) Sales of heavy duty (6 cylinder, 250 - 400 Hp) engines for 10 to 15 tonne trucks, large buses, coaches and large construction equipment has continued to experience high growth. Yuchai sales of 6112 (6 cylinder, 285 Hp) engines grew 34% despite being restricted by insufficient production capacity in 2003. First sales of 6113 (6 cylinder, 300 - 350 Hp) occurred in November 2003. Growth of this new product is expected to be strong over the next few years and we expect to become a significant contributor to profit growth for Yuchai. Early in 2003, Yuchai embarked upon a major capital expenditure program to increase the production capacity of heavy-duty engines by 20,000 units per year and to construct a new foundry. This expansion is expected to be completed on schedule towards the end of first quarter 2004. This expansion is intended to provide a significant opportunity to boost Yuchai's performance in the years ahead. The expansion is expected to enable Yuchai to enter the high growth, higher margin market for engines over 300Hp, while eventually reducing its cost base by replacing imported engines blocks and cylinder heads with production from the new foundry. Yuchai has a strong brand name in China with an extensive sales and marketing network. CYI believes Yuchai's products are considered to be of good quality and provide reliable performance. Yuchai has established itself as a major manufacturer of diesel engines in China with a significant market share. It is generally expected that the market demand for diesel engines in China will increase with the continued expansion of the highways and toll roads in China leading to increasing demand for new trucks, buses and construction equipment. Wrixon F. Gasteen, President, stated "Despite operating in a challenging environment after Severe Acute Respiratory Syndrome ("SARS"), we were able to achieve our financial objectives. I am pleased to announce that with the major capital expenditure program implemented in 2003, Yuchai is expected to make progressively increasing deliveries of the new 6113 heavy-duty engine in the beginning of March this year. This is a significant milestone which is in accordance with our business plan. We strongly believe this new heavy-duty engine will contribute significantly to Yuchai's future financial performance." Basic and diluted net income per share for the year ended December 31, 2003 was Rmb12.40 (US$1.50) compared to a basic and diluted net income per share of Rmb11.67 (US$1.41) for 2002.
