The central government wants Shenzhen to set an example in sustainable development for the rest of the country, an analyst said after Premier Wen Jiabao's whirlwind visit last week. The premier made a brief stopover in Shenzhen on Thursday after attending a leaders' summit for tsunami victims in Jakarta. He visited the Daya Bay nuclear plant and a hi-tech company. Mr Wen told Guangdong leaders that Shenzhen should aim for sustainable growth and improved co-operation with Hong Kong. He also highlighted the city's role as a symbol of the mainland's economic reform and opening policy. 'In this sense, Shenzhen is not only Shenzhen's Shenzhen, nor is it Guangdong's Shenzhen. It is the nation's Shenzhen,' Mr Wen said. Shenzhen Party Secretary Huang Liman said the premier had stressed the central government's support for the city during his one-day visit. 'He told us that the central government holds Shenzhen as a very important city and has pinned high hope on us,' Ms Huang told a group of professors at Shenzhen University last week. It was the second visit by Premier Wen in less than two years. He also sent an inspection team to the city last year to help it formulate a new development strategy. Yang Lixun , a member of the Shenzhen Academy of Social Sciences who briefed the inspection team, said Mr Wen wanted Shenzhen to set an example in sustainable development. 'Shenzhen in the past set a great example for the rest of China in how to develop economically. Now we are one of the richest cities on the mainland, but our other developments are lagging behind,' Professor Yang said. 'Premier Wen wants us not just to focus on economy. He hopes we can shift towards a more balanced, people-based development and set an example.' Professor Yang said the central government wanted Shenzhen to devote more resources to environmental protection, medical facilities, security and building community spirit. 'The economy provides a material base for other development. It is not an end in itself. Shenzhen now needs to pay more attention to other areas, such as pollution,' he said. 'It is not just about Shenzhen. After 20 years of rapid economic growth, China now needs to have a more comprehensive development strategy. 'Premier Wen believes Shenzhen can lead the new trend, just like we did 20 years ago.'
