China's fixed investment jumped 53 percent in the first two months of this year,compared to 26.7 percent recorded last year.It was unexpecedly fast growth,despite possible inaccuracies due to recent statistical adjustments by the National Bureau of Statistics(NBS).The soaring investment data once again raised the risk of Chinese economic growth.Although the government emphasized that overinvestment has only happened in a few sectors such as steel,cement and aluminum,it seems the overheating situation is expanding to the whole economy,both from infrastructure and downstream sectors.
