BEIJING, May 15 (Xinhua) -- Chinese police closed 168,000 cases of financial crime and recovered 35.6 billion yuan (5.2 billion U.S. dollars) last year, the Ministry of Public Security announced on Monday.

According to the ministry, the frequency of financial crime is still high in China. Cases of illegal fund-raising, pyramid selling, online peer-to-peer fraud, securities and futures crime, counterfeit money and bank card fraud have infringed on the interests of investors and undermined market stability.

The ministry pledges to continue to strike hard against financial crime and calls for the public to report any knowledge of financial crimes to public security authorities.
