China's police have solved over 28,000 cases with 18 billion yuan (2.84 billion U.S. dollars) involved over the course of a year-long crackdown on intellectual property rights (IPR) infringements and counterfeit goods.

If calculated in terms of the prices of the licensed products, total amount of money involved could top 500 billion yuan, said a statement from the Ministry of Public Security on Sunday (MPS).

From November 2010 to this October, police across the country have closed more than 22,000 illegal sites producing violation products and busted 6,700 criminal rings responsible for selling such goods, the statement said.

The police on Sunday kicked off a special campaign in the northern city of Tianjin to scrap the violation items seized in the crackdown campaign.

This campaign will be launched in 182 Chinese cities. It is estimated that more than 25 million fake luxury goods, pirated books and discs, and counterfeit medicines and foods will be destroyed, the statement said.
