The central government has seized fake golf equipment estimated to be worth more than US$5 million in a nationwide crackdown but critics said the efforts were not enough. The mainland authorities launched a series of raids on factories and retail stores from Beijing to Shenzhen, seizing fake golf clubs, balls, shoes, bags and garments, said the US Golf Manufacturers Anti-Counterfeiting Working Group. The crackdown was launched after recent meetings between Chris Israel, the US International Intellectual Property Rights Enforcement Coordinator, and Vice-Premier Wu Yi, when Beijing promised tougher enforcement of intellectual property rights. In one raid, about 100 officials and police officers descended on the Beijing Silk Market and shut down all fake golf retail operations. 'This is one of the most intense enforcement efforts I have seen on behalf of any industry by the Chinese government,' said Loo Shih Yann, a principal in international law firm Baker & McKenzie coordinating efforts for the US Golf Manufacturers Group. 'However, the efforts lack bite because no infringers were arrested,' said Mr Loo. Until counterfeiters were subject to criminal penalties and jail sentences, the latest round of raids would not have a serious deterrent effect and merely add to the costs of them doing business, he said.
