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.

VIENTIANE, March 28 (Xinhua) -- The trade and economic cooperation between China and Laos has made outstanding progress in recent years and it is endowed with promising future, Lao Prime Minister Bouasone Bouphavanh told Xinhua here about the prospect of Sino-Lao relations.     "The Sino-Lao cooperation will be more efficient and pragmatic under the Greater Mekong Subregion (GMS) economic cooperation mechanism," said Bouasone. Lao Prime Minister Bouasone Bouphavanh speaks during an exclusive interview with Xinhua prior to the upcoming Third GMS Summit on Friday, March 28, 2008.In an exclusive interview with Xinhua prior to the upcoming Third GMS Summit, where leaders of the six GMS countries -- Cambodia, China, Laos, Myanmar, Thailand, and Vietnam, will be meeting in Vientiane, Laos on 30-31 March 2008 to discuss the progress and chart future directions in GMS cooperation, Bouasone highly valued the compressive development of the bilateral relations between the two GMS member countries.     China and Laos have traditional friendship and enjoy healthy and steady development under the principles of long-term stability, good neighborliness, mutual trust and comprehensive cooperation, Bouasone said.     There have been frequent exchanges of high-profile visits especially since the entering of the 21st century. The two countries leaders sincerely exchanged views on lots of bilateral, regional and international issues and reached a wide range of consensus with the signing of a series of friendly cooperation agreements, he added.     In 2007, the volume of bilateral trade between Laos and C

The average pork price has dropped to 12.61 yuan this week, 9.61 percent lower than the peak price on August 9, said China's economic planner after pork prices nearly doubled in the past eight months due to short supply and mounting production costs.The prices have seen a consecutive drop for the eighth week, down by 3.45 percent from the end of August, as the piglets raised since May and June grew ready for the market to add to the pork supply.Pigs daily butchered in 36 major cities have increased by 12.6 percent from August, and the supply is expected to keep rising, said the National Development and Reform Commission.But the Ministry of Commerce said the decline in the pork prices would probably stop as demand surges during the ongoing National Day holiday and feedstuff prices stay high.The soaring pork prices is a major contributor to the general food price hikes that drive up the consumer price index to a 6.5 percent increase in August.

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.
