Shenzhen will spend 200 million yuan this year to upgrade its police force, with its new mayor vowing yesterday to rid the city of its reputation as China's crime capital. The Shenzhen People's Congress yesterday confirmed Xu Zongheng as mayor, replacing Li Hongzhong , who has become the party secretary. The new mayor said security and co-operation with Hong Kong would be at the top of his agenda. He said the Shenzhen People's Congress received more than 500 public proposals during its annual session, which ended yesterday. Most were about public safety. 'We need to put pressure on criminals. I hope the street safety will be much better five years from now,' Mr Xu said. He said his government would increase co-operation with Hong Kong and establish a mechanism to improve communication between the two cities. 'Our biggest advantage is our closeness with Hong Kong. To strengthen this link would be our top priority.' Mr Xu, a Hunan native, was Shenzhen's executive vice-mayor before his promotion yesterday. He is a business graduate from the China Politics and Law University.
