BEIJING -- Beijing has seen a 30 percent decrease in residents' complaints about airborne debris around construction sites in the first 11 months of this year compared with a year earlier, the municipal environment authorities said Sunday.The city fined 7,467 construction sites in 2007 for failing to control dust, involving a total of about 10 million yuan (US.3 million), according to the municipal environmental watchdog. The city also  fined more than 4,000 illegal outdoor barbeques and rubbish incineration facilities.The city reached its goal of 245 "blue sky" days for 2007 on Sunday, when a cold front helped the city hit an annual air quality improvement target just two days before the year ends.Statistics also show that although the number of "blue-sky" days did not increase dramatically, Beijing recorded only three heavily-polluted days this year, sharply down from last year's 13.The Chinese capital launched a drive, "Defending the Blue Sky," in 1998, when it only had 100 days of fairly good air quality. The Olympic host city aims to make 70 percent of the days in 2008 meet the standard.

China will undertake nearly 10 percent of an international fusion-research project to be implemented this year.The project is called ITER and wants to demonstrate the scientific and technical feasibility of fusion power - the energy of the sun or hydrogen bomb - for peaceful use."The project aims to find a shortcut to solve our energy shortage," Luo Delong, deputy director of the ITER China Office, said at the Oriental Science and Technology Forum held in Shanghai over the weekend.He said Chinese researchers will be in charge of producing various components of the project and escorting them into Cadarache in the south of France where the ITER's key equipment will be constructed.China will inject about one billion yuan (US7.5 million) into the project, accounting for nearly 10 percent of the overall ITER investment, officials said.Other partners in the project include the European Union, the United States, Japan, India and Russia.According to Zhang Jie, a fusion-power scientist of Jiao Tong University, researchers of universities in Shanghai, including Fudan and Donghua, are conducting fusion-related studies.China will further enhance its education in the area to lift the country's overall research power.The long-term objective of the research is to harness fusion nuclear energy to help meet the future energy needs of mankind, project officials said.The aim of ITER is to show fusion can be used to generate electrical power and do the preparation work to build and operate an electricity-producing plant.The key part of the project is to develop a viable fusion-power reactor.Scientists of ITER will test a number of key technologies, including the heating, control, diagnostic and remote maintenance that will be needed for a real fusion-power station, officials said.Local experts said fusion may produce dozens of times more energy than fission, which now directs most of the world's nuclear-power plants.Fission can only be caused by uranium. However, the resource to trigger fusion can be found in ordinary substances from the sea, they said.According to the Website of ITER, the overall construction cost of ITER is estimated at five billion euros (US.37 billion) over 10 years and another five billion euros are earmarked for the 20-year operation period.The ITER organization owns the ITER device and is responsible for all aspects of the project, such as licensing procedures, hardware procurements and operation.

SHANGHAI, March 5 (Xinhua) -- A traditional commodity fair in east China, conventionally regarded as a barometer of the nation's foreign trade, reported less demands from American businessmen than expected, indicating a possible slowdown of Sino-U.S. trade.     The 18th East China Commodity Fair, an event held at the beginning of every year, reported around 1,600 American businessmen, far less than expected.     "The number of the American businessmen to the fair was only two thirds of those from the European Union, showing the deficient domestic demands of the United States," said Wang Qingjiang, an official with the fair.     "The subprime crisis in the United States has shown its influence on China's exports," he added.     The 5-day fair registered total business deals worth 583 million U.S. dollars between Chinese companies and the U.S. businessmen, a 1.5 percent dip from last year.     Deals worth more than 3.67 billion U.S. dollars were signed at the fair, a 3.52 percent growth from 2007.     Deals between Chinese companies and the European Union businessmen added up to 879 million U.S. dollars, a 9.5 percent growth compared with the last fair.     Chinese companies and the Japanese businessmen made deals worth906 million U.S. dollars, almost the same amount compared with last year.     The fair attracted more than 19,000 businessmen from 145 countries and regions around the world, with more than 60 percent from Asia.     According to experts, the fair could indicate the trend in China's foreign trade in 2008.

Yahoo co-founder Jerry Yang said on Wednesday that China is fertile ground for an online advertising exchange akin to the one the US Internet titan is buying. The comment was among insights Yang shared with more than 1,000 Chinese and US technology entrepreneurs gathered in the California city of Santa Clara to discuss opportunities and challenges presented by the meteoric growth of China's economy. US Internet giant Yahoo co-founder Jerry Yang during a presentation in a Tokyo hotel, March 2006. Yang said on Wednesday that China is fertile ground for an online advertising exchange akin to the one the US Internet titan is buying.[AFP] "I'm going to call Jack Ma up with this idea of an exchange for advertisers and ad buyers," Yang said, referring to the chairman of Chinese Internet company Alibaba.com. "The potential is huge." In August 2005, Yahoo invested one billion dollars for a 40 percent stake in Alibaba, which also agreed to run the Chinese operations of the US Internet giant. Yang said that as it neared its second anniversary, the Yahoo-Alibaba partnership has "some catching up to do" in the online search and portal business in China but that he expected a turnaround in a few years. "On the whole, we feel our move to partner with Alibaba so far looks like it's the right strategy," Yang said. "It is too early to tell whether we are successful or not." "The best strategy still seems to be Chinese and US companies sharing best practices ¡ª we all benefit." Yahoo is buying New York City-based online advertising exchange Right Media in a move to counter Google's move to acquire the DoubleClick Internet ad-targeting firm. The California online search titan, which owns 20 percent of Right Media, said it will acquire the remaining 80 percent of the company for 680 million dollars (500 million euros) in stock and cash. The ad exchange serves as a place where advertisers can easily "hook-up" with websites or online services that cater to desired customer demographics. While announcing on April 13 that it was buying New York-based DoubleClick for 3.1 billion dollars, Google revealed plans for the Internet ad tracking and targeting firm to create an open exchange similar to Right Media.

BEIJING - State Forestry Administration investigators found more than 100 suspected footprints of a South China tiger on Friday in Shaanxi Province, where photos of the big cat taken by a farmer have caused a national controversy over their authenticity.A South China tiger [File photo] The Beijing Morning Post reported on Monday that Zhang Bin, a local forestry official who accompanied the investigators, said the team also found a skeleton suspected to belong to a young tiger."It's like the skeleton of a cat," said Zhang, adding the bones had been sent to Beijing for DNA testing. "But experts said with a length of 50 centimeters, a cat would have grown tooth bones. This skeleton hasn't (teeth), it's like a cub feline.""The experts said there is a great probability that it belongs to a South China tiger cub."He said the footprints found in Zhenping County ranged from 12 to 16 cm, with toes. "To my experience in investigating the wild, they are tiger footprints. They belong to more than one tiger."Zhang said the experts had also developed rubbings of the footprints for further analysis.In October, a farmer in Zhenping County, in the northern Shaanxi Province, claimed he snapped photos of a tiger in the forest near his home. The provincial forestry bureau later cited experts as verifying it was a South China tiger. The subspecies was believed to have been extinct in the wild for more than three decades.However, many scientists and Internet users have denounced the pictures as fake. In November, one netizen posted an on-line picture of a tiger from a new year calendar and claimed the two tigers were identical.Despite this, the provincial forestry department insisted the tiger in the photo existed in Zhenping County. The Beijing-based China Photographers Society, however, confirmed the images were not real.Last month, the State Forestry Administration dispatched an expert panel to Zhenping to carry out a field investigation. It hoped to find concrete evidence on whether the tiger existed.The photo taken by Zhou Zhenglong, a farmer in Zhenping County of Northwest China's Shaanxi Province. Zhou claimed he snapped photos of a South China tiger in the forest near his home.
