SHENZHEN'S Mayor, Li Youwei, yesterday vowed to promote more exchanges with Hongkong and Guangdong. Mr Li, recently promoted to the Guangdong Communist Party Standing Committee, said Shenzhen was keen to seek a ''better convergence'' with Hongkong before and after 1997. Speaking at a municipal party committee meeting, Mr Li said Shenzhen would not only open Shatoujiao and Yantian Harbour as bond-free districts, but would ultimately turn the whole city into a duty free area. Mr Li also emphasised the importance of closer co-operation between Shenzhen and the rest of Guangdong in China's new age of reforms. In particular, Mr Li said Guangdong enterprises would enjoy ''priority consideration'' if they sought listings on the Shenzhen Stock Exchange and the Special Economic Zone (SEZ) would join other Guangdong cities to attract foreign investment. Shenzhen would provide extra funding to help Guangdong in its education, anti-poverty and old enterprise reform programmes. Guangdong enterprises would also be given preference in their applications to set up offices in the SEZ. The new measures were to be debated in the working meeting and were expected to be adopted as government policies. Mr Li has repeatedly pressed Beijing for ''extra preferential policies'' saying they were essential for the SEZ to maintain its pioneer status in China's reform. Sources said Shenzhen and Guangdong had been at loggerheads for years.
