DuPont reported that its sales in China witnessed a 30 per cent rise last year, anticipating that the strong growth will continue this year.

Charles Browne, president of DuPont China Holding Co, said the company plans to invest in new projects and expand investment and capacity of existing projects.

He added that, with China's entry into the World Trade Organisation, DuPont has started to integrate its China business into a global logistics system to better leverage the worldwide supply of raw materials.

DuPont started business in China in the mid-1980s. By the end of last month, the company had invested more than $500m there.
