A former top official of Guangxi Zhuang Autonomous Region has been jailed for 18 years for corruption. Sun Yu , 52, deputy chairman of the region from 1998 to 2007, accepted 3.28 million yuan (HK$3.72 million) in bribes from the end of 2004 to mid-2007, the China News Service reported. In return, Sun helped businesses obtain raw materials and timber licences. Sun was the fourth top Guangxi official sacked for corruption in less than a decade. Cheng Kejie, the region's former chairman and a deputy chairman of the National People's Congress in the late 1990s, was executed in 2000 for accepting bribes of 41 million yuan. Two other deputy chairmen, Xu Bingsong and Liu Zhibing, were jailed for graft in 1999 and 2006 respectively. Nanning Intermediate People's Court said in the judgment on Monday that Sun also embezzled 3 million yuan in government funds from phantom projects. The report said most bribes and part of the embezzled funds had been seized and Sun had confessed, which the court had taken into account during sentencing. A further 1 million yuan, described as 'personal property', was also seized. The influential Caijing magazine reported that Sun may have been involved in a corruption scandal at a major water control project on the Li river in Guilin . As deputy director of Pearl River flood prevention general headquarters, Sun was in charge of building dams and reservoirs worth about 577 million yuan, the magazine said. Caijing quoted a source as saying that Sun had a 'close relationship' with at least four married women and that one of their husbands may have reported him to the authorities.
