WUXI: Premier Wen Jiabao has demanded a thorough investigation of the Taihu Lake crisis, which has affected the drinking water supply of about 2 million people. Efforts to protect the lake from further pollution are also to be scrutinized. "The pollution of Taihu Lake has sounded the alarm for us," Wen said in a directive to a symposium held by the State Council here yesterday. Taihu Lake, which was once a scenic attraction famous for its aquatic life, including shrimp, lily and water chestnuts, has been heavily polluted by industrial, agricultural and domestic waste. Wen said efforts had been made to reduce pollution in Taihu Lake in recent years. "But the problem has never been tackled at the root," he added. He asked participants in the symposium, including officials from central and local governments, environmental workers, scholars and researchers, to thoroughly investigate the Taihu Lake crisis so that concrete measures could be drawn up in response. Vice-Premier Zeng Peiyan, who attended the symposium, told governments at all levels to work to prevent algae blooms and ensure the safety of drinking water. Zeng asked local governments to continue collecting the blue-green algae, intensify monitoring of water quality, ensure the water supply and divert more water from the Yangtze River to flush out the pollution. He also asked environmental watchdogs to strengthen supervision and punish factories that discharge pollutants into Taihu Lake. At the meeting, all towns around Taihu were ordered to establish sewage treatment plants. Chemical factories will have to meet a new water emissions standard by the end of June next year. Towns must set up sewage treatment plants and are forbidden from discharging untreated sewage into Taihu Lake or rivers in the Taihu valley. Existing plants must install nitrogen and phosphorus removal facilities before the deadline, according to the plan announced at the meeting. Chemical factories that fail to meet the new water emissions standard risk suspension. They will be shut down permanently if they fail to meet the standard by the end of next June. The new water emission standard for the Taihu area will raise the bar for sulfur dioxide emissions and chemical oxygen demand. China Daily-Xinhua

WASHINGTON -- The special US envoy on Sudan affairs said Wednesday that important progress has been made toward peace talks on Darfur and China plays a "constructive" role in facilitating such progress."I am very happy with the role the Chinese are playing," Andrew Natsios said in a speech at the Center for Strategic and International Studies, a Washington-based think tank."It is a constructive role," Natsios said. "I think the Chinese are like a locomotive that is speeding up."With mediation by China, he said, the Sudanese government has accepted a UN Security Council resolution adopted in July to authorize a hybrid UN-African Union peacekeeping force for the Darfur region.He said the major obstacles to the peace talks now come from the rebel groups rather than the Sudanese government.In a related development, China's Special Representative on African Affairs Liu Guijin said in Beijing on Tuesday that China will send a military liaison officer to Sudan's Darfur.Liu, who has just wrapped up a seven-day visit to the United States and the United Nations, said China has informed the UN of its decision.China also pledged to send a 315-member multi-functional engineering unit to Darfur in early October, which would be the first batch of UN-AU peacekeepers in place, and China will stick to its commitment, Liu said.Liu reiterated China's constructive and unique role in finding a solution to the Darfur issue, saying China has provided much aid and help with regard to the reconstruction and development of Darfur."The US and UN both hold positive views on China's role in resolving the Darfur issue, and hope China will play a bigger role in this regard," said Liu.

China, with a record .2 trillion of foreign-exchange reserves, will keep the "bulk" of its US dollar holdings because the currency is one of safest investment options, a People's Bank of China assistant governor said. The dollar remains "important" because trade and foreign direct investment is conducted mostly in the currency, Yi Gang told delegates at a meeting that was closed to the media at the World Economic Forum in Singapore. Asian central banks will continue to hold most of their reserves in dollars, he said. "Safety, return and liquidity are the three most important elements that people should consider when they talk about reserves," Yi said in a recording of the discussion that was obtained by Bloomberg News. "As far as we're concerned, the serious reduction of the dollar reserve is a small probability," he said, adding that any adjustments to its dollar holdings will be "incremental." China's gross domestic product expanded 11.1 percent in the first quarter, making it the world's fastest-growing major economy, led by sustained demand for its exports to the US and other trading partners. Diversification of the nation's foreign-exchange reserves will be gradual and won't hurt the dollar or financial markets, Market News International said last month, citing Ding Zhijie, one of five advisers to the reserves agency's committee. 'Gradual Process' China's trade surplus, which the Asian Development Bank estimated will climb by 45 percent to a record 7 billion next year, has sparked calls for further gains in China's yuan. Some US lawmakers have said that the yuan was undervalued by 40 percent to make China's exports cheap and pledged trade sanctions as punishment. The central bank expects the yuan exchange rate will gradually move toward a "market-oriented direction," Yi told reporters after the meeting Monday. The currency has risen about 8.6 percent since the dollar link was abandoned in July 2005. "The central bank of China has the responsibility to keep the exchange rate at more or less a stable level," Yi said. "The mechanism is more toward a market-oriented direction."

CHENGDU: Thick fog continued to blanket parts of western and central China Sunday, causing traffic accidents, flight delays and highway closures.Plunging visibility from the bad weather delayed more than 150 flights and left 12,000 passengers stranded Sunday in the Shuangliu International Airport in this capital of Sichuan Province, airport officials said.The airport was closed for nearly nine hours Sunday morning before a flight to Tibet took place at 11:10 am."Full operations did not return to normal until more than an hour later when the first flight from Shenzhen in Guangdong Province landed here," airport publicity department official Liu Gang told China Daily."It was the second day visibility in the airport had been at about 10m."On Saturday morning, a heavy fog fell on Chengdu, shrouding its downtown areas and six suburban counties with a visibility of under 50m.The airport itself was closed for eight hours that day, with 121 flights delayed and 11,000 passengers stranded.Sichuan weather bureau deputy chief Zhong Xiaoping said environmental pollution was a major cause of the fog.Zhong advised citizens to take buses more often, save energy, cut car exhaust, and play a part in the recycling of waste materials.More than 10,000 vehicles were stranded from the fog on highways Sunday, about 4,000 more than the day before, the Chengdu Transportation Bureau said. It advised residents to take trains in the next few days.He Ping, a 49-year-old company employee, drove from Deyang in northern Sichuan to Chengdu through the Chengdu-Mianyang Expressway Sunday afternoon."I've driven for nearly 20 years and have never seen such heavy fog before. I could not even see the line separating the fast lane from the slow one," He told China Daily.Meanwhile, heavy fog also persisted in Hebei, Henan and Shaanxi provinces for consecutive days. The poor visibility forced highways to close and delayed flights Sunday.The Xi'an-Baoji Expressway in Shaanxi Province was closed on Saturday as visibility in some sections was less than 2m.Meteorologists also attributed the fog to a combination of high humidity, lower temperatures and low wind speeds in the affected regions.Xinhua contributed to the story
