China has no laws to effectively curb bribery cases involving multinationals, state media reported, and cases may be on the rise. More than 60% of 500,000 cases of commercial bribery investigated in the past decade involved international trade and foreign businessmen, according to a Democracy & Law Times report quoted in other state media. The number of commercial corruption cases is up. Xiong Xuanguo, vice-president of the Supreme People's Court, said courts at all levels dealt with 5,429 commercial bribery cases involving civil servants in the first three quarters of 2006, up 10.43% from 2005. Multinationals have been linked to the fall of Zhang Enzhao, the former president of China Construction Bank sentenced last month in Beijing to 15 years in prison for accepting more than US$506,000 in bribes.
