CHANGSHA -- Central China's Hunan Province said it has taken effective measures to prevent epidemics after about 2 billion rats chomped their way through cropland around the Dongting Lake, the country's second largest freshwater lake. "It's not possible for rodent-borne diseases to break out in the lake area," said Chen Xiaochun, vice director of the provincial health department. Local health authorities have been watching closely over the rodent situation after the rats fled their flooded island homes and invaded 22 counties around the Dongting Lake last week, he told a press conference on Wednesday. Results of their observation are reported daily to the provincial health department and the public, he said. Meanwhile, local health and disease prevention and control authorities have intensified management of raticide and pesticide, for fear they might contaminate food and water, Chen added. No human infection of any rat-borne disease has been reported in the central Chinese province since 1944. The provincial government also ruled out widespread suspicions that rats flooded the area because one of their natural enemies -- snakes -- had been served at dinner tables. "The Dongting Lake area is not an ideal habitat for snakes," said Deng Sanlong, a top forestry official in the province, "and the only two species that inhabitate the region feed largely on fish and frogs." He said the top enemy of the rats are hawks that spend winter in the wetland around the lake but fly away in spring. China's Ministry of Agriculture and the Hunan provincial government have allocated 900,000 yuan in total to eradicate the rats.

Yichang - Construction of a tunnel under the Yangtze River that will form part of a gas pipeline project running from Sichuan Province to Shanghai was completed Monday.The 1.4-km, 3.08-m diameter tunnel sits 20 m beneath the riverbed and connects two wells on either side of the river in Yichang city, Hubei Province, Liu Juzheng, head of the Hubei section of the pipeline, said.With a total length of 2,203 km, the pipeline will serve as an "energy artery" as part of the West-East gas project, Liu said.The pipeline is expected to channel 12.1 billion cu m of natural gas a year from the Puguang field in Sichuan to central and eastern regions of the country, including Chongqing Municipality, the provinces of Hubei, Anhui, Jiangxi, Jiangsu and Zhejiang, and Shanghai Municipality.The tunnel, which took 325 days to complete, is the first of five to be built under the Yangtze.Industry experts say the new pipeline, which will cost 62.7 billion yuan (.4 billion) to build, will provide an opportunity to develop western regions based on their rich natural resources.Chen Deming, vice-minister of the National Development and Reform Commission (NDRC), said the pipeline will be completed in late 2010 and the gas it transports will help reduce carbon dioxide emissions by tens of millions of tons a year.Figures from the China Petrochemical Corporation (Sinopec) put Puguang's proven reserves at 356.1 billion cu m. The country has total proven natural gas reserves of about 2.66 trillion cu m.The government has been promoting the use of natural gas to improve energy efficiency and reduce air pollution.Under an NDRC proposal on natural gas development, the government plans to increase the natural gas pipeline network to 44,000 km by 2010 to meet demand.Although China's natural gas output will reach 94 billion cu m in 2010, up from 58.6 billion in 2006, an additional 16 billion cu m a year will still have to be imported to meet demand, Sinopec said.In Shanghai, demand for natural gas soared from 4 million cu m in 2003 to 1.9 billion in 2005.In 2004, China National Petroleum Corp (CNPC) opened its West-East gas pipeline, which runs more than 4,000 km and channels 1.2 billion cu m of gas a year to Shanghai from the Tarim Basin in the country's westernmost region of Xinjiang.CNPC is to build a second West-East pipeline to carry gas imported from central Asia to the Pearl and Yangtze river deltas. Construction will begin next year with the line, which is designed to carry 30 billion cu m a year, becoming operational in 2010.

BEIJING -- China will continue to spend more on education next year and spread the free nine-year compulsory education to urban children, said finance minister Xie Xuren.The government would continue to improve the funding system to guarantee free nine-year compulsory education currently enjoyed by 150 million rural children, while spreading it to their urban counterparts next year, Xie told an annual conference of the Ministry of Finance in BeijingStarting from the spring term, China would increase the funding for free textbooks used for the national compulsory courses, and the local governments would provide more money for free textbooks for local compulsory courses, he said. Local governments would also provide scholarships to cover the living costs of boarding students from poor families. The central government would provide half of the education funding for areas in Central and West China, while provincial governments in those areas would cover the rest of the costs.Local governments in East China would provide all education fees with some supplementary funding from the central government.Xie said the government would issue new standards for per capita expenditure of students in primary and middle schools, and put those standards into effect within the next two years.He said the allowance for maintenance and refurbishing of rural schools in Central and West China would also be raised with special financial support to high-altitude and cold areas.In addition, the government would continue free education for students taking courses for teaching careers at normal schools and provide scholarships for poor undergraduates and students at vocational schools.According to Xie, the first 11 months saw  557.8 billion yuan (about 74.3 billion US dollars) of fiscal expenditure used for education, up 32.7 percent compared with the same period last year.As a result of the implementation of scholarships for the poor, about four million college students and 16 million secondary vocational school students had benefited.

The US government should withdraw its complaint against China to the WTO over the intellectual property rights (IPR) issue, China's top IPR official reiterated on Tuesday. "The Chinese government has always been firm in protecting intellectual property rights and attained significant achievements in this respect. It's not a sensible move for the US government to file a complaint against China to the WTO," said Tian Lipu, director of the State Intellectual Property Office (SIPO). The United States filed two WTO complaints against China over copyright piracy and restrictions on the sale of US books, music, videos and movies early April. "As far as I know, negotiators from China and the US are still in the consultation stages within the WTO framework," Tian said, speaking at a seminar organized by the World Intellectual Property Organization (WIPO) and SIPO in Beijing. He said that it was still hard to predict the result of the consultation since it was the first time China had handled such a complaint. "But we will respond to it positively according to WTO rules and fight through to the end," Tian vowed. According to rules set by WTO, trade negotiators from both countries should try to resolve the dispute within a 60-day consultation period from the day the complaint was lodged. Otherwise, the United States can ask the WTO to establish investigative panels. Tian said it was unreasonable for the United States to ignore the huge progress achieved by China in IPR protection. He stressed that the amount of invention patent applications in China ranked fourth in the world last year and it increased by 28.4 percent on average between 2000 and 2006. "IPR protection is a natural option for building an innovative country. It also serves China's goal for overall development. Therefore, the Chinese government will continue its efforts to protect IPR and combat copyright piracy no matter what decisions the US makes," Tian noted.

Aerospace experts saved the country's first ever manned space mission as the spaceship faced a potentially lethal impact while flying through the communications blackout area before landing, the country's space authorities revealed yesterday.China became only the third country to put a man in space, after the former Soviet Union and the United States, when Yang Liwei orbited the Earth in 2003 in what was a resounding success for its space program.But Xinhua News Agency reported that this was almost not so, quoting the Xi'an Satellite Monitor and Control Center's report on the dangers the Shenzhou V rocket faced."Yang lost every means to communicate with the ground command and control headquarters as he entered the ( Earth atmosphere), which fell in the worst-case scenario prepared by the space mission team," Xinhua quoted Dong Deyi, head of the center, as saying.Communications go down when any spacecraft re-enters the Earth's atmosphere, but in Yang's case, "even radar could not capture any signal from the returning module", Dong was quoted as saying. "After the Shenzhou V came out of the blackout area, the echo signals from the spaceship were still volatile, which sufficiently threatened the safe landing of astronaut Yang."Mission control promptly ordered optical guiding and tracking instead of a communication-guided landing, Dong was quoted as saying."Aerospace technologists used cinetheodolites (optical trackers) on the ground to measure the spacecraft's position and record movements. Precise positioning of the spacecraft enabled officers to properly control the slow-down parachute, which was vital to a soft landing."But the landing was 9 km east of the planned site, Dong said.China began its clandestine manned space program in 1992. The country has since spent at least 20 billion yuan (.64 billion) on the project and sent three astronauts into orbit.Dong also revealed that at least three orbiting satellites were malfunctioning during certain periods, but all had been salvaged by experts since October 2006.The Xi'an center, established on June 23, 1967, in the mountains of Northwest China, has monitored and controlled more than 100 satellites and the six Shenzhou spaceships. According to official records, China now has at least 19 satellites orbiting the earth.China plans to chart every inch of the moon's surface as part of its ambitious space program.China, which plans to launch a lunar orbiter called "Chang'e I" in the second half of this year to take 3D images, would aim to land an unmanned vehicle on its surface by 2010, Zhang Yunchuan, minister of the commission of science, technology and industry for national defense, said on Friday.Xinhua-Agencies
