KHARTOUM: Chinese peacekeepers were on Wednesday awarded certificates of merit for their excellent performance during their eight-month term in Sudan, a Chinese officer said Thursday.Lieutenant General Jasbir Singh Lidder, commander of the UN Mission in Sudan (UNMIS), presented Unit Citations to the engineering, transportation and medical contingents of Chinese peacekeeping troops, and Force Commander Commendations to 22 Chinese troops.The two certificates of merit are the highest honor awarded to peacekeepers from various contributing countries in Sudan, said the Chinese officer.The awards ceremony was held at the base of the Chinese peacekeeping troops in Wau, capital of West Bahr al-Ghazal state in southern Sudan, two weeks before their departure from Sudan to rotate with another batch of Chinese peacekeeping troops.Lidder said it was a great honor for him to serve with the Chinese peacekeepers as they were ending "their very successful term" in Sudan."During the past months, the three contingents of the Chinese peacekeeping troops have done a significant job to be a role model for professionalism, commitment and conduct," Lidder said.The Chinese peacekeepers had also maintained excellent relations with the contingents of other countries as well as the local population, the UNMIS commander said.Li Chengwen, the Chinese Ambassador to Sudan, congratulated all the three contingents, the 22 Chinese peacekeepers as well as the other officers and soldiers. He highly praised their performance in Sudan, especially in the extremely difficult and complicated conditions.The 435-strong Chinese peacekeeping troops, the second batch of Chinese peacekeepers deployed in southern Sudan since China started taking part in UN peacekeeping operation there in May last year and arrived in Wau in January this year.

Poor planning not natural events was to blame for a spate of deadly accidents recently, safety chief Li Yizhong said.In the latest major incident, 172 miners are still trapped underground nearly three weeks after floodwater inundated the Huayuan mine in Xintai, East China's Shandong Province. Rescue work is ongoing.There have been 18 major accidents (with at least 10 people killed each) since July 18. Seven of these incidents have been triggered by natural events."The root is some local authorities and companies have failed to take sufficient action to tackle safety loopholes and build a sound early-warning mechanism," the chief of the State Administration of Work Safety said on Tuesday.Learning from these "bloody lessons" will prevent "accidents triggered by natural disasters," Li said.In a circular issued last Friday the State Council urged mines that risk being flooded to stop production when typhoons land or there is torrential rain.The circular also asked mine owners to identify hidden natural dangers and remove them."We feel it is urgent to improve emergency rescue mechanisms and carry out more training and drills," Li said.He cited two explosions at a natural gasfield in Kaixian County, Chongqing, which had very different outcomes.The first incident killed 243 people in 2003. But in 2006, nobody was killed when there was a similar incident because emergency plans were in place and there had been drills.The work safety situation in China is grim despite a decline in the death toll over the first eight months of this year, Li said.Statistics showed 61,919 people were killed in various work accidents nationwide between January and August. This was 13.9 percent lower than over the same period last year.The number of major accidents with 10 or more deaths during the same period has dropped by 14.7 percent year on year.In response to the high number of fatal accidents the State Council Work Safety Committee has sent about 300 people, in 24 teams, to carry out safety checkups across the country, starting August 27 and ending September 20.

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.

The central government has ordered coal firms to stop driving up prices and said they must honor their supply contracts with power plants in an effort to head off a power shortage.At the request of the National Development and Reform Commission, the China Coal Transportation and Distribution Association has threatened to cancel the license of any company that ignores the order to stabilize prices."Coal producers must strictly implement their contract prices for 2008 and must not take advantage of the current tight supply to raise prices as they like," the association said in a circular issued yesterday.Prices should be held at around the same level as at the end of last year, the circular said.The government is also banning all coal shipments other than those to power plants.The crackdown comes as the country faces a severe power shortage. Several power plants are struggling to secure the coal they need, while others are reducing their output rather than lose money as coal prices soar.Brownouts have already hit at least 13 provinces, and at its peak last week, nationwide demand outstripped supply by nearly 70 gigawatts, the People's Daily newspaper reported yesterday.About 80 percent of China's electricity is generated by burning coal.The crackdown on unsafe mines, high global demand, which pushed up prices and the cold snap that has closed roads and downed cables have added to the problem, an official from the State regulator said.

BEIJING, March 24 (Xinhua) -- Chinese commercial banks will be allowed to trade gold futures in the domestic market, according to a notice released on the regulator's official website here on Monday.     China gold futures trading was launched in January, but domestic banks were barred from trading by the China Banking Regulatory Commission.     According to the notice, domestic banks that meet certain requirements, such as having capital adequacy ratio of more than 8percent, can apply for a trading permit.     "That's great news for the gold futures market, which is not operating that well," said Hu Yuyue, an expert with Beijing Technology and Business University.     "Commercial banks can provide more liquidity and stability to the market, after all, they hold huge capital," said Hu.     "Gold futures trading can also help domestic banks to improve competitiveness against overseas banks as financial derivatives are supposed to be the largest revenue sources for leading banks," he said.     Non-interest income usually accounts for at least 50 percent of bank revenues in developed countries and the proportion can reach 80 percent for some banks.     However, Chinese banks depend heavily on the margins between deposits and loans.
