Xu Gang, former vice governor of Fujian province in East China, is charged with taking advantage of his positions to seek benefits for others and accepting a "huge amount" of bribes.

Xu Jianyi, former party chief and chairman of major Chinese automaker FAW Group, is accused of taking advantage of his positions to seek profits for others as well as accepting bribes.
