CHINA'S regional economic warlords have been told not to overheat the economy, but speed up reform, by the chairman of the National People's Congress. Qiao Shi made the remark during a recent visit to the western province of Sichuan. Accompanied by liberal Sichuan Governor Xiao Yang, Mr Qiao reportedly said cadres must grasp the present golden opportunity to build a better China. ''At present, the international environment is very favourable to China's reform and opening up,'' Mr Qiao was quoted by the China News Service as saying. ''Moreover, the domestic environment is also very good. The country is stable and the economy is generally on an upward trend,'' he added. However, Mr Qiao who is not known for his expertise in the economy, also issued a warning to the cadres. ''We must keep a sober mind, avoid blind and duplicate low-efficient investment to prevent economic overheating,'' he said. Speaking in Chongqing, Mr Qiao praised the city for transforming its hundreds of military enterprises into market-oriented companies. The NPC chairman also instructed the peasant-denominated province to ''seek a new path'' in developing the Three Gorges Dam area. ''The migration work involved is very difficult, so everyone should be more creative and not look at this task as just simple resettlement or development so there would be no undesirable consequences,'' Mr Qiao said. ''With careful planning, [we] should handle this like a mission and look for new solutions,'' he said. The mammoth dam which is to be built across the Yangtze in Sichuan has been hailed by Beijing as the largest hydro-power project in history.
