Beijing is planting trees and plants along riverbanks instead of covering them with concrete to fix its river system. It has taken almost 10 years for the capital to accept and use this idea. The ecosystems in the streams are gradually coming back to life because of the cleaner water, providing a good habitat for animals and plants, and ideal leisure sites for local residents.  Zhuanhe which connects with Kun Ming Lake in the Summer Palace is one of successful example of the river ecological treatment in Beijing. "In Beijing, there are 52 rivers with a total length of 520 kilometers inside the sixth ring road. Yongding and Jingmi rivers are the city's two main water sources, and Qinghe, Bahe, Tonghui and Liangshui are key drainage waterways," said Yu Kongjian, dean of the Sight Engineer Institute with Peking University. Originally, Beijing only wanted to control the floods by letting water flow out as soon as possible. Therefore, riverbanks were cemented down in order to prevent water leakage and the growth of plants, which could slow the water speed down. However, the shortage of rainfall in Beijing since 1999 showed that this method was not correct. On the one hand, streams had less fresh water to clean themselves. On the other, more polluted water was dumped into the rivers as more people moved into the capital. And in the summer of 2001, something bad happened. "The rivers in Beijing turned blue overnight and gave off a smelly odor," said Liu Peibin, vice engineer of Beijing Water Authority. There was an algae bloom due to so much pollution in the water. Algae covered the water surface and consumed most of the oxygen, and many creatures in the water died as a result. These "concrete pools" became the haven for swarms of mosquitoes which forced tens of thousands of residents nearby to close their windows and doors tightly especially in summer days. The water authorities had to act quickly for public safety. The first step was to demolish the concrete covering the riverbanks. The soil was exposed to water again, and the water could circulate down to the riverbank. Secondly, in order to stimulate oxygen in the streams, engineers put big stones in the water to create mini waterfalls. And they grew trees like willows and plants such as bulrush along the riverbanks. "Bulrush can purify polluted water through absorbing nitrogen and phosphorus in the water and exhaling oxygen," Deng added. "Gradually Zhuanhe came back to life and got rid of the polluted and smelly water. This would be impossible today if the brook was still covered in concrete." "What we did with Zhuanhe is a milestone in the progress of river treatment with new ecological ideas," said Deng Zhuozhi, vice engineer of Beijing Water Project Institute. He took charge of the Zhuanhe project. "How to fix up rivers depends on our attitude towards floods. We should learn to make friends with floods in a country where two-thirds of China's cities are short of water. Therefore we should reserve water as much as possible instead of discharging it ineffectively," said Yu.

KUNMING -- A gas blast in a private coal mine has killed at least seven miners and injured five in southwest China's Yunnan Province, sources with the local government said Saturday.The blast occurred around 6:00 a.m. Saturday in the Shunxing Coal Mine in Fuyuan Township of Qujing City, in eastern Yunnan. Twenty-seven miners were working underground, and fourteen people managed to escape.More than 400 rescuers struggled to pull out seven bodies and five miners alive. One miner remains missing.The injured workers are being treated in a local hospital.The coal mine, which was built in 1984 with a designed production capacity of 90,000 tons, had been ordered to suspend operation and go through renovation after county coal mine administration staffs inspected the mine on Friday, but coal mine managers secretly organized the miners to work in the night.Local officials are investigating into the cause of the accident.

Chinese government said on Tuesday Vietnam had caused concern by agreeing with BP, a British oil company, to build a gas pipeline in the South China Sea. "China has indisputable sovereignty over the Nansha Islands and neighboring areas," Foreign Ministry spokesman Qin Gang said in Beijing."Vietnam's new actions infringing on China's sovereignty, sovereign power and administrative rights in the Nansha Islands (in the South China Sea) go against the important consensus reached by leaders of the two countries on this maritime issue," he emphasized. "It is not beneficial to stability in the South China Sea area. China is paying close attention, and we have already made serious representations to the Vietnamese side," the spokesman said. "With everyone's hard work, the situation in the South China Sea has been stable." Qin also said that the February13 agreement on the Democratic People's Republic of Korea (DPRK) nuclear issue may have run afoul of some difficulties, but that does not mean the Six-Party Talks have failed or will be rendered invalid."(The difficulties) are natural because the talks have never been smooth, but the fact that the situation has encountered difficulties doesn't mean that the talks don't work," Qin said at a news conference. All parties are committed to the idea that negotiations are the only way to achieve a stable, nuclear-free Korean Peninsula and the normalization of diplomatic ties, he added. The DPRK (North Korea) walked out of the Six-Party Talks last month when the transfer of million that had been frozen at Banco Delta Asia in Macao did not come through. The latest agreement between the parties gives Pyongyang 60 days to shut down its nuclear facilities in return for energy aid. That deadline falls on Saturday. The US Treasury Department has said that Macao authorities are prepared to unblock the frozen funds. The government of Macao Special Administrative Region said it was aware of the US Treasury statement and that it would work with all parties involved. "Simultaneously, it expects all parties concerned to come up with appropriate and responsible arrangements," the government said on its website. Qin said Bank of China, which had been initially prepared to accept the frozen funds on behalf of Pyongyang, still needed more time to think about it. "It is a publicly listed company and has to conform to its international obligations and laws," he said. As for the Darfur issue, Qin said that China hoped that former UN secretary-general Kofi Annan's peace plan would be implemented and that the UN troops would be employed as early as possible.

China has paid its dues to the UN in time, one of China's representatives to the world body has said."This year, assessed contributions (UN membership dues) and peacekeeping assessments both will go up significantly for China, with the total being 0 million, a 42 percent increase against last year," a member of China's delegation to the Fifth Committee of the 62nd UN General Assembly, Yu Hong, said.Speaking at a conference on "Improving the Financial Situation" of the UN in New York last week, he said China has provided equipment worth more than million to its peacekeeping troops in Sudan and Liberia, too.The country will pay the bulk of its outstanding peacekeeping dues before the end of the year, Yu said."China has a very good reputation in fulfilling its financial promises to the UN," Wu Miaofa, a UN expert with the China Institute for International Studies, said. "China has become an active participant and constructor of the organization."The increase in China's financial contribution and its fulfilment of the promises show that it's willing to shoulder more international responsibility, he said.The UN's financial condition has deteriorated this year because of the rise in unpaid contributions."A sound financial condition is most important for the UN to perform its functions as the most important world body," Wu said, urging all member states to honor their financial obligations in time.

BEIJING - China welcomed Sudan's acceptance of a joint African Union- United Nations peacekeeping force for the country's troubled Darfur region. A Sudanese diplomat in Ethiopia confirmed on Wednesday that Sudan has accepted the mission after receiving assurances that a "hybrid" AU-UN force of 17,000 to 19,000 troops will not be open-ended and Sudan will remain in control of its borders. "China welcomes the deployment of a hybrid AU-UN force in Darfur and the joint statement," Foreign Ministry spokesman Qin Gang said in a statement posted on the ministry's Web site late Wednesday. "The facts have shown that dialogue and equal negotiation is an effective approach to political solution of the Darfur issue, and the consultation between AU, UN and Sudan is an effective mechanism," Qin said. China recently appointed a special representative for Africa to focus on Darfur, and has publicly urged Khartoum to give the UN a greater role in trying to resolve the conflict. The Darfur conflict began in 2003 when local rebels took up arms against the Sudanese government, accusing it of decades of neglect. Sudanese leaders are accused of unleashing the pro-government Arab militia, the janjaweed, to fight them - a charge they deny.
