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.

CHENGDU: Thick fog continued to blanket parts of western and central China Sunday, causing traffic accidents, flight delays and highway closures.Plunging visibility from the bad weather delayed more than 150 flights and left 12,000 passengers stranded Sunday in the Shuangliu International Airport in this capital of Sichuan Province, airport officials said.The airport was closed for nearly nine hours Sunday morning before a flight to Tibet took place at 11:10 am."Full operations did not return to normal until more than an hour later when the first flight from Shenzhen in Guangdong Province landed here," airport publicity department official Liu Gang told China Daily."It was the second day visibility in the airport had been at about 10m."On Saturday morning, a heavy fog fell on Chengdu, shrouding its downtown areas and six suburban counties with a visibility of under 50m.The airport itself was closed for eight hours that day, with 121 flights delayed and 11,000 passengers stranded.Sichuan weather bureau deputy chief Zhong Xiaoping said environmental pollution was a major cause of the fog.Zhong advised citizens to take buses more often, save energy, cut car exhaust, and play a part in the recycling of waste materials.More than 10,000 vehicles were stranded from the fog on highways Sunday, about 4,000 more than the day before, the Chengdu Transportation Bureau said. It advised residents to take trains in the next few days.He Ping, a 49-year-old company employee, drove from Deyang in northern Sichuan to Chengdu through the Chengdu-Mianyang Expressway Sunday afternoon."I've driven for nearly 20 years and have never seen such heavy fog before. I could not even see the line separating the fast lane from the slow one," He told China Daily.Meanwhile, heavy fog also persisted in Hebei, Henan and Shaanxi provinces for consecutive days. The poor visibility forced highways to close and delayed flights Sunday.The Xi'an-Baoji Expressway in Shaanxi Province was closed on Saturday as visibility in some sections was less than 2m.Meteorologists also attributed the fog to a combination of high humidity, lower temperatures and low wind speeds in the affected regions.Xinhua contributed to the story

Executives of China's major edible oil manufacturers and guild leaders were summoned to Beijing on Monday for a closed door meeting at which the government required them to step up production to rein in the soaring market prices.An official with the National Development and Reform Commission (NDRC) who asked not to be identified said it was understandable for the edible oil processing firms to raise prices as the continuous rise in the cost of raw materials had increased their production costs.However, the public had responded strongly to the price hikes of edible oils, coming as they did with rapid rises in the prices of other goods, the official said.Edible oil makers were told to "deepen their sense of social responsibility" and "bear the overall interests of the country in mind".Incomplete statistics from various regions show prices of domestic edible oils rose by 20 percent from November last year to June as the prices of peanuts and other oil-bearing products had risen.In eastern Shandong Province, first grade peanut oil has risen by 28.6 percent from 14,000 yuan per ton in April to a record 18,000 yuan per ton. While supermarkets marked down cooking oils to boost sales, people were reportedly standing in long queues. On Oct. 26 in Shanghai, 15 shoppers were injured after people swarmed in a local supermarket to snap up edible oils on sale only five minutes after the store opened.But the latest weekly market monitoring report by the Ministry of Commerce showed the prices of cooking oils fluctuated only slightly from Oct. 22 to 28, with the prices of peanut oil edging up 0.1 percent from a week earlier, while rapeseed oil was down 0.1 percent, and soybean and blended oils were basically the same.Wang Hanzhong, director of the Oil Crop Institution of the Chinese Academy of Agricultural Sciences, attributed the price hikes to a shortfall of oil crop output as the acreage under oil crops had dwindled drastically. Major oil crop producer Hubei Province, for example, had found the acreage under rapeseed shrank from 18 million mu to 15 million mu last year. The situations in Sichuan, Anhui and Jiangsu were even worse.Soaring domestic demand that registered an annual average growth of 8.95 percent from 14.54 million tons in 2001 to 22.35 million tons in 2006, had aggravated the problem, turning China into the world's largest edible oil consumer. Domestic edible oil supply met just 40 percent of domestic demand.In a statement after the meeting, the NDRC spelled out five requests including the supply of more small-package oil to meet market demand.Oil processors were not allowed to disturb market order or stoke up fears for price hikes by hoarding raw materials, rigging raw material supply, cutting production or restricting supply.Price hikes must be kept within reasonable margins and be made when absolutely necessary, it said, adding that oil processors must enhance cost controls, improve management and absorb the costs from raw materials as much as possible.The NDRC also warned large cooking oil makers not to collude in setting prices or provide short measures or shoddy products.Under current price conditions, enterprises should transfer part of their interests to the people and cherish their public reputation, it said.Industrial associations were required to provide guidance to firms, make sure they abide by laws and regulations, admonish enterprises in cases of unfair competition, and keep market supervisors informed of the malpractice.If the price hikes exceeded the extra production costs, market supervisors would step in, it warned.Without identifying the participating cooking oil makers, the statement said that representatives from business communities had promised to maintain market order with their actions and contribute to the stabilization of market prices.China's consumer price index, a key measure of inflation, rose by 6.2 percent in September after hitting an 11-year high of 6.5 percent in August, while food prices jumped by 16.9 percent from January to September over the same period of last year, figures from the National Bureau of Statistics showed.The Ministry of Agriculture released 11 measures in late September, including rewards to major oil crop planting counties as well as total subsidies of 300 million yuan for soybean cultivation and assistance of one billion yuan for rapeseed cultivation.The import duty on soy beans was also cut from three percent to one percent. The State Grain Administration released 200,000 tons of state edible oil reserve to meet rising demand prior to the the National Day holiday that fell on October 1.

BEIJING - China purchased at least 400 billion yuan (.6 billion) of goods and services in 2007, a new high compared to the 368.1 billion yuan recorded a year earlier, preliminary figures from the Ministry of Finance (MOF) revealed.Assistant Financial Minister Zhang Tong described the expansion as "outstanding" given the procurement stood at only 100 billion yuan in 2002, the first year the mechanism was introduced.The past five years have also witnessed an increasingly diversified government consumption that expanded from solely commodities in the beginning to services and engineering, he said. With 13,000 people engaged in purchasing nationwide, China has twice revised its procurement list to include 18 categories encompassing nearly 4,770 items.Energy-saving products accounted for a large percentage of the newly-added items. To lead by example, the government has pledged to reduce energy consumption for every 10,000 yuan of gross domestic product by 20 percent and pollutant emissions by 10 percent for the 2006-2010 period.This year, student textbooks for primary and junior high schools, medicine, farm machinery and other items to distribute to the needy free of charge or at inexpensive prices will be added to the list, Financial Minister Xie Xuren told a recent work meeting for 2008.Under a MOF directive promulgated last month, government procurement will favor independent innovation products starting this year, a practice, experts said, the United States adopted in the late 1950s to foster domestic high-tech industries, including aeronautic and astronautic technology, computing, semiconductors and integrated circuits.Qinghua University law professor Yu An said the move would provide good incentives for domestic firms to speed up technical innovation.MOF statistics revealed the procurement had spared an aggregate expenditure of at least 180 billion yuan between 2002 and 2007.The benefits, however, didn't drown out grumbles from the Heilongjiang provincial chapter of the Revolutionary Committee of the Chinese Kuomintang, one of the country's eight political parties, beside the ruling Communist Party of China (CPC).At a meeting last month, the chapter held transparency in government procurement should be enhanced as some products were found to be overpriced, of unsatisfactory quality or without effective after-sales service.Tendering companies must be subject to real-time supervision to avoid bribery and kickbacks. Perpetrating firms must be blacklisted and banned from the procurement, while governmental departments must submit their accounting ledgers for regular auditing scrutiny, they said.

Chinese officials said water quality was improving in the country's third-largest lake, choked by a polluted slick of algae, but experts warned that tap water in the area was still not safe, state media reported on Saturday. Taihu Lake, in the southern province of Jiangsu, has been struck by a foul-smelling canopy of algae that left tap water undrinkable for more than 2.3 million residents of nearby Wuxi and prompted a run on bottled water at local supermarkets. Residents said the government was telling them it was safe to drink boiled water, but complained that it still had an unappealing green film on top. Environment experts said it was unlikely to be fit to drink. "Although quality of the water supply has improved significantly on Friday and now it is safe for washing hands or clothes, it still takes some time to become drinkable," the Zhang Xiaojian, an environment specialist at Tsinghua University in Beijing said. Algae blooms can develop in water that is rich in nutrients, often because of run-off from heavy fertiliser use, industrial waste and untreated sewage. Officials have invoked emergency measures, diverting the Yangtze river and seeding clouds to provoke rainfall, to try to flush out the algae. Heavy rainfall is also expected in the area in the next few days. Residents of Wuxi said the algae, which they said smelt like rotten meat, was driving a roaring trade at McDonald's and KFC fast-food outlets in the city. "Here they fry food," said a company manager named Zhao as he queued at KFC. "I can't eat dumplings or noodles because they would be cooked in water and it's too expensive to use bottled water."
