Fatal riots in Vietnam have eroded the interest of some Chinese companies in investing in the country, according to a garment industry official.

Some textile companies in Foshan of South China's Guangdong province suspended trips to Vietnam that had been planned to assess the investment environment, said Wu Haoliang, secretary-general of Foshan Textile and Garment Industry Association on Tuesday.

A Foshan-invested textile plant in Ho Chi Minh City was slightly damaged, although no one was injured, he said.
