A senior Party leader from Guangdong province vowed on Wednesday to take tougher action against prostitution and crimes linked to the sex trade as the southern economic powerhouse continues its three-month crackdown on prostitution.

"We will continue our investigation into the prostitution industry and strengthen our efforts to tackle the problem," said Hu Chunhua, Party chief of Guangdong.

Hu made the remarks at a panel discussion during the annual session of the National People's Congress, which convened in Beijing on Wednesday.
