PREMIER Zhu Rongji expressed support for a proposal to grant residents of Beijing, Shanghai and Shenzhen permits allowing them one-day visa-free entry to Hong Kong.But he has not received any formal government document on the proposal yet. He would give the final go-ahead if he receives a formal plan, he was quoted as saying by Hong Kong’s Phoenix TV yesterday.Zhu was asked by Hong Kong reporters whether he supported the policy during the Earth Summit in South Africa.But some Hong Kong experts predict that the visa-free policy could not be implemented within a short period of time due to technical problems.Chief Secretary of the HKSAR Government Donald Tsang said in Hong Kong that the Hong Kong side is negotiating with mainland authorities to seek ways to quicken border crossings.Another high-ranking official said any suggestions benefiting Hong Kong’s tourism and economic development were welcome. <2001>(Li Jing)
