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.

Chinese photographers said the South China tiger on digital pictures, released by forestry authorities and widely discussed on the Internet, is a fake.A preparatory digital picture appraisal center under the China Photographers Society, released the results on Sunday after a team of photographic experts assessed the 40 digital pictures provided by NetEase, a Chinese Internet company.The State Forestry Administration, however, on Tuesday refused to comment on the authenticity of these pictures, saying its responsibility is to protect the wildlife.Cao Qingyao, SFA spokesman, did cite previous investigation resultsat a press conference in Beijing, saying the investigators found some traces of South China tigers in Shaanxi, and said a new investigation in the area is under way, and the results will be announced as soon as possible. The center said technological analysis from last Tuesday through Sunday showed the South China tiger on the 40 pictures was not real and could not serve as evidence for the existence of the wild animal.The pictures must have been taken by people with photographic experience or under guidance and could not be done independently by a person without any photographic experience, claimed experts.The digital picture, purporting to be a wild South China tiger crouching in the midst of green bushes, was released by the Forestry Department of northwest China's Shaanxi Province at a news conference on October12.Zhou Zhenglong, 52, a farmer and former hunter in Chengguan Township of Shaanxi's Zhenping County, photographed the tiger with a digital camera and on film on the afternoon of October 3, a department spokesman said.The Shaanxi forestry department said it had confirmed the 40 digital pictures and 31 film photographs were genuine.But the pictures released were not the original ones and they underwent modifications, such as time and signal, according to experts.Bao Kun, an expert who participated in the appraisal by the center, told Xinhua they announced the results out of "a citizen's sense of social responsibility."A detailed report concerning the appraisal would be announced in about a week, Bao added.In response to the appraisal results, the Shaanxi provincial forestry department said in a written statement to media that they had already "showed their attitude toward the South China tiger issue and would continue to pay attention to the matter.""We thank netizens and media for your care of the South China tiger and of the wildlife protection cause," the statement said, offering no direct comment on the appraisal results."In a statement on November 23 the department said: "We firmly believe this basic fact: That wild South China tigers exist in Zhenping county of Shaanxi Province."The South China tiger, from which other sub-species such as the Siberian tiger evolved, is listed as one of the world's ten most endangered animals.It is the only tiger subspecies native to China's central and southern areas. In the early 1950s, its population was 4,000 across the country. Since 1964, no sightings of wild tigers have been reported in Shaanxi.Its former habitats were in Guangdong Province, Guangxi Zhuang Autonomous Region and the central provinces of Hunan and Jiangxi.

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.

China warmly welcomes French President Nicolas Sarkozy on a state visit next month, which will "be a great event for China-France relations", Foreign Minister Yang Jiechi said at a joint press conference with his French counterpart Wednesday.Yang and French Foreign Minister Bernard Kouchner discussed the preparations for Sarkozy's visit, and agreed that it would definitely achieve great results.A lot of agreements will be inked between France and China during Sarkozy's visit in areas such as energy, transportation and education, Kouchner said.The French foreign minister is in China to pave the way for Sarkozy's visit, the first since he assumed presidency in May.During their talks, Yang said China is ready to go along with France to deepen strategic dialogue, expand mutually beneficial cooperation and have closer consultation and coordination on major international issues.The two foreign ministers agreed, as two of the five permanent members of the UN Security Council, to strengthen comprehensive strategic partnership for the benefit of both sides. Such a development will be beneficial to global peace, stability and development, too.On the development of ties between China and the European Union (EU), Yang said their relationship had matured after 30 years of cooperation."The two sides share broad common interests in intensifying mutual political trust, expanding economic and trade cooperation, jointly tackling the challenges of climate change and combating traditional and non-traditional security threat," Yang said.Kouchner ensured Yang that France would double its efforts to solve the pending China-EU problems after his country assumed the rotating presidency of the EU in July 2008.On the Taiwan question, Kouchner said France follows the one-China policy. He said EU foreign policy chief Javier Solana had made a statement on behalf of EU countries opposing Taiwan authorities' attempt to hold a referendum to move the UN for membership. "France supports the position (of Solana)," Kouchner said.Yang and Kouchner also exchanged views on regional and international matters such as the nuclear issues on the Korean Peninsula and in Iran, the situation in Myanmar, climate change and the Darfur and other issues in Africa.

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.
