Premier Wen Jiabao has paid a whirlwind visit to Shenzhen, urging the city to work closely with Hong Kong on 'economic, science and technology and cultural areas'. The premier, who left Jakarta on Thursday after attending a leaders' summit for tsunami victims, told Guangdong leaders on Friday that the border city should aim for sustainable development while trying to break new ground on reforms, Xinhua said. Both the Wen Wei Po and Ta Kung Pao said Mr Wen had stopped in Shenzhen because he was concerned about the energy shortage and drought in Guangdong. According to Xinhua, Mr Wen visited the Daya Bay nuclear plant and a hi-tech company. He encouraged Shenzhen to upgrade its investment environment and to be careful with land resources. 'He also asked Shenzhen to thoroughly implement what the central government has asked of her on work regarding Hong Kong,' Xinhua said. 'This means [Shenzhen] should work closely with the SAR in economic, science and technology and cultural areas.' It was the second visit by Mr Wen to Shenzhen in less than two years. He toured the city in 2003 after making a high-profile visit to Hong Kong.
