Housing projects in small cities would be limited to no more than 7 hectares each, those in medium-sized cities to 14 hectares and large cities to 20 hectares, according to a statement posted on the Ministry of Land Resources Web site Tuesday. There were previously no size restrictions. The ministry won't grant land-use permission for new coal mines with annual output capacity of less than 1.2 million tons. The limit comes into effect after the government's current five-year economic plan ends next year. Curbs would apply to provinces including Shanxi, Inner Mongolia and Shaanxi, the report said. New polysilicon projects won't be granted land-use permits unless they have capacity of more than 3,000 tons a year and use fewer than 6 hectares per thousand tons of output. Polysilicon is used in the manufacture of solar power modules. Land-use curbs will also be imposed on dairy processing, textiles and construction materials, the report said, without providing more details. Chinese authorities have rejected US$28 billion worth of steel and other proposed industrial projects as they try to curb chaotic overinvestment the government worries could lead to economic trouble. Business groups and economists have warned that the government's huge stimulus might fuel a dangerous boom and bust. The government responded in September by announcing investment curbs on industries that produce steel, cement, glass, polysilicon used in solar panels and wind power equipment. Authorities are especially concerned about the steel industry, which already is the world's largest. It is expanding rapidly as construction companies buy materials for stimulus-financed public works projects. (SD-Agencies) Shenzhen Daily
