China’s nine-month campaign to crackdown on intellectual property violations has been the country’s most successful one to date, resulting in the closure of numerous websites hosting pirated materials and the confiscation of hordes of fake electronic goods, according to Chinese authorities. The campaign ran from October to June, and cases solved involved counterfeit goods worth 13.1 billion yuan (US$2 billion). The campaign resulted in 9,031 arrests, according to China’s Ministry of Commerce vice minister Jiang Zengwei, who spoke on the matter during a press conference on Tuesday. He also refuted claims that the campaign was more bark than bite, given that China has held crackdowns on intellectual property violations before. “This time, the measures and effectiveness of the Chinese government’s operations are unprecedented,” he said.
