Senior cadres have warned officials in the 10 western provinces not to take advantage of the 'go west' campaign to hatch fantastic or wasteful projects. Speaking on the fringes of the National People's Congress and Chinese People's Political Consultative Conference, the leadership also cited the need to curb corruption in the build-up-the-west crusade. NPC Chairman Li Peng told delegates from the western province of Shaanxi that they must aim for realistic development plans. 'To successfully implement the develop-the-west strategy, local areas need to have a clear knowledge of their advantages and weaknesses,' Mr Li was quoted as saying yesterday. 'They must plan well and conduct feasibility studies and adopt concrete measures in that regard.' Mr Li said that despite Beijing's aid programme, people in Shaanxi must rely on themselves for development. He suggested Shaanxi focus on developing new and hi-tech industries, bio-engineering, information projects and horticulture. Vice-President Hu Jintao said building up a corps of honest, competent officials was the key to opening up the west. Mr Hu, the principal of the Central Party School, told delegates from the poor Guizhou province that 'party construction' must be boosted in the western provinces. 'Cadres must maintain a self-disciplined, just and clean image,' the China News Service quoted Mr Hu as saying. Economists and academics have cited corruption as one of the pitfalls of the build-the-west programme. Meanwhile, local cadres have taken advantage of the NPC and CPPCC to lobby for different schemes, including a push by legislators from Chongqing for a stock exchange to be opened in the directly administered city. Deputy Yun Mingshan said the bourse in Shenzhen should be moved to Chongqing, with a Nasdaq-like second board being established in its place in the special economic zone. Liberal deputy Zheng Zuohui said Beijing should adopt the 'Californian model', whereby private investors bore the cost of laying down the infrastructure in return for the right to reap the benefits of development.
