Marketing became more important  At present, the large-scale passenger car market continues to be weak, and there is no sign of recovery in the near term

29 2H 2009 Outlook Market Outlook

Challenges  As a result of China’s economic slowdown and the impact of the global financial crisis, companies are faced with challenges in external environment due to weak domestic demand, export and investor sentiments  Competition in the heavy-duty truck market will intensify in the next few years

Opportunities  China will remain one of the fastest-growing economies in the world with huge growth potential. Increased economic activities will help bring about a stable economic recovery  The markets of construction machinery, engineering machinery and ancillary logistics vehicles are likely to benefit from the Central government’s 4-trillion stimulus package. As more property projects commence and government construction projects come through the pipeline, demand for loaders is likely to grow  China’s economy remains healthy. The national stimulus package is set to drive recovery in the economy and help lift the freight and cargo business  The implementation of fuel tax, a toll-by-weight policy and National III Emission Standard will lead to upgrades in industry infrastructure in high-tonnage heavy-duty trucks market  With an overall decline in purchasing power in overseas markets, lower priced Chinese-made vehicles will become more competitive

Looking ahead in the second half of 2009, China’s economy will be relatively stable and healthy. Weichai Power is cautiously optimistic about the heavy-duty truck industry. In view of the effect of the national investment plan as well as increases in construction works in the real estate industry, the outlook for wheel loaders is optimistic
