GUANGZHOU: Doctors in this city have developed a new birth control surgery for men that could be made available to the public starting next year.The method involves making a small incision along the testicle. Doctors then place a tiny tube, about the size of a match, into the opening.The tube functions as a filter that blocks sperm, Wu Weixiong, the director of Guangzhou Family Planning Technology Center, said.The surgery has already been patented, and the health department will promote it as soon as it is approved by the National Food and Drug Administration, Zhu Jiaming, the vice-president of the Guangzhou Sexology Association, said.He expects approval to be granted by next year."The success rate for this form of birth control is 97 percent," he said.The tube can be removed without negatively affecting a man's sexual health, he said.Wu said the operation takes just 10 minutes. However, it is very difficult and requires highly skilled doctors.He said only a few hospitals have the staff and facilities necessary to carry out the procedure. However, training courses will soon be made available to local doctors.Wu said he believed enough facilities and manpower would be available to handle the demand for such operations by the time the procedure is officially approved."The success rate of the operation is almost 100 percent," Duan Jianhua, an official of Guangzhou population and family planning commission, said.Research on the operation started four years ago in Beijing. It was led by the science and technology institute of the National Population and Family Planning Commission and Guangzhou family planning science and technology institute.Wu said the technique was developed through more than 1,600 clinical trials all over the country. More than 500 men in Qingyuan, a city in Guangdong Province, have already had the operation. All the trials were successful and none of the subjects has experienced any side effects.Zhu Jiaming said the operation costs just a few thousand yuan, which is affordable for most people in China."When the technique is available, couples will have one more option for birth control, and married women do not have to install an intrauterine device (IUD) anymore," Zhu said.The public seems ready."I welcome this technique. It makes me feel women are more respected by society than before," Liu Jun, a woman in Guangzhou, said.A survey by the Guangzhou-based New Express Daily found that about 60 percent of Guangzhou residents welcomed the surgery and supported its promotion.

BEIJING, March 21 (Xinhua)-- Personal computer giant Dell Inc. said Thursday that it will raise parts purchases from China by 27.8 percent this year, increasing its presence in the booming market.     Dell is to buy 23 billion U.S. dollars worth of computer components and other equipment from Chinese suppliers this year, compared with 18 billion U.S. dollars in 2007, said Michael Dell, chief executive officer of the PC giant, at a press conference.     However, Dell's Beijing representative office denied reports that the company was planning to buy 29 billion U.S. dollars of computer parts from China in 2009.     To secure a bigger share of the Chinese market, Dell broke with its Internet sales model and sealed a deal in September to sell PCs through the country's top electronics retailer, GOME Electrical Appliances.     Dell saw its PC shipments in China up 54 percent year-on-year in 2007.     The company plans to expand its retail outlets from 45 cities in 2007 to 1,200 by the end of the year.     China, where Dell ranks third in terms of market share, is one of the company's fastest growing markets, said Michael Dell.     Dell has two factories in Xiamen, a coastal city in southeastern Fujian Province, a design center in Shanghai and a customer contact center in Dalian, a northeast coastal city, with more than 6,000 employees in China.     Meanwhile, Dell estimates it will contribute more than 50 billion U.S. dollars to China's gross domestic product (GDP) this year, and provide about 2 million jobs.     Dell also said it would donate 1.7 million yuan (239,436 U.S. dollars) to build six education centers in China to teach computer skills to migrant workers' children.

The country's trade surplus last month continued its downward trend, with efforts to curb exports paying off and imports rising, authorities said on Friday.Figures from customs authorities showed the trade surplus last month was .49 billion, below December's .7 billion and the record high of .1 billion set in October last year."For the first time since May, the trade surplus is under billion," customs said on its website.Exports rose 26.7 percent from a year earlier to 9.66 billion, while imports rose 27.6 percent to .17 billion, the government agency said. Import growth outpaced exports for the fourth month in a row.Experts said the surplus dropped due to policies put in place last year to curb exports. The authorities had introduced a raft of policies since early last year, including VAT cuts, to discourage exports of energy-intensive, polluting products."China's policies to encourage imports and cut the trade surplus are also helping a lot," Zhang Xinfa, an economist with Beijing-based China Galaxy Securities, said.As a result of the tightening policy, the processing trade last month was .85 billion, up 15.8 percent year on year. But the growth rate slowed by 9.9 points compared with the same period last year.The appreciation of the yuan also played a role in curbing exports."Many exporters are facing difficulties due to rising costs and the yuan's appreciation, and export momentum will ease in the coming months," Li Yushi, a researcher on trade with the Ministry of Commerce, said.According to Li Peng, spokesman for Asia Footwear Association, more than 1,000 shoe factories in Guangdong province closed down last year.The firms went bankrupt due to high costs driven by the removal of an export tax refund, a stronger yuan, rising raw material prices and labor costs, Li said.The stronger yuan also makes imports cheaper, which is one reason behind the strength seen in Friday's data, Zhang said.The European Union remained as China's largest trade partner last month, with bilateral trade of .28 billion, up 30.1 percent year on year.The EU was followed by the United States. Trade between China and the US last month increased by 12.2 percent year on year to .23 billion, despite looming recession in the US economy.China's trade surplus last year stood at 2.2 billion, with total trade volume hitting a new high of .17 trillion, up 23.5 percent from a year earlier.

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.

BEIJING - China's food watchdog issued an emergency circular on Wednesday to ensure food safety in the face of severe winter weather that has blocked transport and endangered supplies in much of central, eastern and southern China.The State Food and Drug Administration (SFDA) ordered all the local food and drug bureaus to tighten inspections of food production and sale facilities so as to prevent inferior or fake food from entering the market.The snow, the heaviest in decades in many places, has been falling in China's east, central and southern regions since January 10, causing building collapses, power blackouts, highway closures and crop destruction.The SFDA ordered all local bureaus to maintain food market order and to prosecute law violations, noting supplies of some foods was already tight.The extreme weather in the past two weeks hit as Chinese travelers began one of the world's biggest annual mass migrations for the Chinese Lunar New Year, or the Spring Festival, the most important festival for Chinese family gatherings.The SFDA also ordered local bureaus to promptly report and tackle emergencies and prevent mass incidents of food poisoning.
