BEIJING, March 1 (Xinhua) -- Chinese Vice Premier Hui Liangyu Monday urged local authorities to step up efforts to prevent forest and grassland fires as a severe drought put south China on a high fire alert.Authorities should beef up the supervision of fire sources, and respond scientifically to emergencies to curb major fires and casualties, and protect the public and forests and grassland, Hui said at a teleconference held by the State Council, or the Cabinet.A prolonged drought, which started last autumn, has hit southwest, south and parts of north China.According to the State Forestry Administration (SFA), from November to January, China reported 1,945 forest fires, which damaged 5,112 hectares of forests and killed two people.

BEIJING, Jan. 30 (Xinhua) -- China Unicom, the country's second largest telecom operator, said Saturday its net profit might have dropped by more than 50 percent in 2009, as the one-time gain from the sale of a mobile business laid a higher comparison basis for 2008.China Unicom, in October 2008, sold its Code Division Multiple Access (CDMA) business and related assets to China Telecom, the largest fixed line service provider of the country, which substantially increased the profits of the company in 2008.The company said in a statement filed to the Shanghai Stock Exchange that its profit was also affected by the high costs for its new Wideband-CDMA operations.

BEIJING, March 5 (Xinhua) -- China's Ministry of Commerce spokesman Yao Jian said Friday the U.S. decision to impose preliminary duties on Chinese potassium phosphate salts and coated paper was unfair and discriminatory.Yao said "frequent" countervailing probes by the U.S. into Chinese products have "unfairly restricted normal exports," adding the fresh anti-dumping measures came only two years after the U.S. ruled China's coated paper exports did not harm the domestic industry in November 2007.The two products will face 109 percent and up to 13 percent duties, respectively, according to a U.S. Commerce Department statement Tuesday.Yao said the fundamental reason behind the difficulties in the U.S. coated paper industry was due to weak demand caused by the financial crisis. He said passing the problem on to Chinese manufacturers was unacceptable.He said China firmly opposes abuse of trade protectionist measures by the U.S. and would negotiate with the U.S. over the unfair move to protect the interests of Chinese companies.

BEIJING, Feb. 12 (Xinhua) -- Most of the melamine-tainted milk products recently resurfacing in China have been recalled and destroyed, and none has been put into market or exported, the nation's food safety office said Friday."Due to early discovery and timely check, as of now, most of the tainted milk products have been recalled and destroyed, and none has entered the market or been exported," said the National Food Safety Rectification Office in a statement.Media reports said melamine-tainted dairy products have resurfaced in several Chinese provinces. Explaining why such cases could happen, the office said some producing and processing companies didn't fulfil the responsibilities for food safety and some violators hid tainted milk products or fabricated test reports to dodge inspections.The office urged related departments at all levels to thoroughly investigate the new cases and severely punish violators.In 2008, milk laced with melamine led to the deaths of six babies and sickened 300,000 others who had been fed with baby formula made from tainted milk. Melamine is an industrial compound which can give a false positive on protein tests and cause kidney stones.Melamine-contaminated milk products killed at least six children in 2008 and sickened 300,000In the recently reported melamine-tainted milk cases, some of the tainted milk products were apparently made of old batches of tainted milk powder slated for destruction but hoarded away instead by dairy firms and later repackaged
