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.

The weakening global economic environment will slow down growth in Asia and the Pacific, too, this year, but China, India and Japan are expected to keep up the momentum in the region, says the Economic and Social Survey of Asia-Pacific 2007. The three economies contribute more than 60 percent of the region's GDP and close to 45 percent of its imports, creating considerable opportunities for the whole region, says the survey, to be released today by the United Nations Economic and Social Commission for Asia and the Pacific (UNESCAP). Developing economies in the region grew at 7.9 percent in 2006, up from 7.6 percent in 2005. But their economic growth is projected to slow down to 7.4 percent this year. The decline is mainly because of the unfavorable external environment, including the slowing down of the US economy and falling demand for electronics across the world, says UNESCAP Executive Secretary Kim Hak-Su in a recorded video on the commission's website. The survey shows investment continues to grow in China, while investment and consumption posted healthy gains in the two special administrative regions of Hong Kong and Macao. The survey, however, warns against several downside risks in the region, such as a possible oil price hike, abrupt cooling of the US housing market, vulnerability of the currency, global imbalances and reversal of the Japanese economy after its recovery. To ensure better long-term growth in the region, the survey suggests Asian economies monitor the vulnerability of the currency and boost domestic demand through private investment.

SHENZHEN -- Construction began Saturday on an experimental facility which will offer a platform for Chinese and foreign scientists to work together for discovering a new kind of neutrino oscillation in Shenzhen, South China's Guangdong Province.It was the second biggest cooperation program Chinese high energy scientists ever conducted with other foreign counterparts since October 1988 when the positive-negative electron collider was built in Beijing.Through the collider, scientists from China and the United States have cooperated and carried out legions of scientific research.Saturday's construction commencement function was attended by more than 100 people, including government officials and foreign diplomats, such as Dr. Robin Staffin, Associate Director of Science in the US Department of Energy.Neutrino Oscillation is an intriguing behavior of a sub-atomic particle called neutrino.And the new facility is being built in the mountain near Daya Nuclear Power Plant, which has four reactors with a combined thermal output of 11.6 million kw in operation, and Ling'ao nuclear power plant is not far away. Both nuke power plants will serve as sources of anti-neutrinos for the experiments when the facility is finished.Workers will build three underground experimental halls which will be connected by long tunnels in the mountain that shields the experiment from unwanted cosmic radiation.Each hall will feature a 10-m deep water-pool within which eight anti-neutrino detectors will be deployed. The water protects the detectors from nearby radiation that interferes with the measurement, and helps identify surviving cosmic radiation.And the first experimental hall is expected to be ready by the end of 2008. Commissioning of the detectors in this hall will take place in 2009.Civil engineering construction is anticipated to last about two years, with installation of the last detector scheduled for 2010.Upon completion of the new facility, more than 190 scientists from six countries and regions including the Chinese mainland, Hong Kong, Taiwan Province, the United States and Russia will come over to do research work, according to Chen Hesheng, Chief of the Institute of High Energy Physics with the Chinese Academy of Sciences (CAS).The facility will have a budget of 250 million yuan (US.25 million). And China will be responsible for infrastructure construction and making of four detectors. And the United States will be responsible for making of the rest of the detectors.Wang Yifang, chief scientist on the experiment, said he was confident that the program would make an important contribution to finding a new breakthrough in China's research efforts in particle physics, starting a new horizon in world's neutrino research, and to improving the overall strength of China in science and technology.

SHIJIAZHUANG - A joint investigation team of China and Japan to the Tianyang Food company has not detected abnormity after a half-day inspection tour in the plant, both Japanese and Chinese investigators said here early Wednesday morning."The plant is very clean and well managed, and no abnormity has been detected," a Japanese investigator told the press. Japan will conduct further analysis based on information and data collected in the plant, he said.Wang Daning, director of the department of food import and export safety under the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ), said that China and Japan have been cooperating well with each other, and the Chinese side has been letting Japanese investigators see related materials and equipments as many as possible.So far, Japanese police have confirmed that at least 10 people fell sick after eating dumplings laced with the highly toxic organophosphate pesticide called methamidophos made by Tianyang Food.Both governments of China and Japan have been struggling to find what actually had happened. A Japanese investigation team came to China and held talks with China Tuesday morning, then to Tianyang Food in Shijiazhuang in the afternoon and worked till 1 a.m. the next morning.
