SHANGHAI - One experimental clean-energy car runs on natural gas. Another uses ethanol distilled from corn. A third has a zero-emissions electric motor powered by a hydrogen fuel cell. Visitors walk around a Ryuga Mazda car on display during The Shanghai Auto Show in Shanghai April 21, 2007. These alternative vehicles were created not by a global automaker but by China's small but ambitious car companies, which displayed them Sunday alongside gasoline-powered sedans and sport utility vehicles at the start of the Shanghai Auto Show. At a time when they are still trying to establish themselves in international markets, Chinese automakers are already investing in such avant-garde research in a bid to win a foothold in the next generation of technology. "This is the tide of the industry. If you don't go with the tide, the industry will pass you by," said Qin Lihong, a vice president of China's biggest domestic automaker, Chery Auto Co., in an interview ahead of the show's opening. China's leaders are encouraging the development as part of efforts to cut pollution and rising dependence on imported oil and to make this country a creator of profitable technologies. Chinese manufacturers are getting help from foreign automakers in joint ventures and from research alliances with Chinese universities and government laboratories. Beijing has made cleaner cars a policy priority, targeting the field as one of 11 priority areas in a 15-year technology development plan issued in February 2006. It promised grants and tax breaks to support industry efforts. The campaign embodies one of Beijing's strategies in technology development: Pick new areas with no entrenched competitors so China can make breakthroughs without huge costs. While foreign automakers have a lead in conventional technology, "in new energy we're starting from almost the same line," said Chen Hong, the president of Shanghai Automotive Industries Corp. "So we believe we can catch up with other auto companies and make great progress in developing new energy vehicles," Chen said. China's leaders are pressing its auto, steel, manufacturing and other industries to improve energy efficiency and cut pollution. They see China's rising reliance on imported oil as a strategic weakness. China already is the world's No. 2 oil consumer after the United States and saw imports soar by 14.5 percent in 2006, driven by economic growth that has topped 10 percent for the past four years. A boom in car sales has added to smog shrouding China's major cities, which are among the world's dirtiest. Vehicle sales jumped 25.1 percent last year to 7.2 million units, including 3.8 million passenger cars. At the Shanghai show, both SAIC and Chery displayed experimental fuel-cell sedans, while they and a third Chinese automaker, Chang'an Automobile Group Co., also showed gasoline-electric hybrids. SAIC said it will start selling its hybrid next year, while Qin said Chery's would go on the market in two to three years. "The hybrid will be our focus," SAIC chairman Hu Maoyan said at a news conference. "The fuel cell will be our direction." SAIC has spent 100 million yuan ( million) on fuel cell research, according to state media. Chery had the widest array of alternative vehicles on display at the Shanghai show. They included models outfitted to run on bio-diesel made from vegetable oil or a "flexible fuel" choice of compressed natural gas or ethanol. Foreign automakers also are playing a role in China's research. General Motors Corp. has a joint-venture technology center with SAIC in Shanghai and operates three experimental fuel cell buses in the city. DaimlerChrysler AG has three of its own fuel cell buses running regular routes in Beijing in a research project with the technology ministry. Foreign automakers including GM, Ford Motor Co., BMW AG and Honda Motor Co. displayed their own hybrids and experimental fuel cell cars at the Shanghai show. Company officials said hydrogen fuel cells, which produce power with no exhaust, are the cleanest option. But they say it could be a decade or more before such technology is commercially feasible, due partly to the need to create a network of hydrogen filling stations. Chinese authorities also are looking at other possible fuels such as natural gas and methane extracted from coal, said Mei-Wei Cheng, the president of Ford's China operations. "This is not an easy decision, because every option has pros and cons," Cheng said. "The government is trying to find a solution as quickly as possible, but this is a difficult problem."

BEIJING -- China's first lunar probe Chang'e-1 will fly to the moon orbit with no more orbital corrections, a scientist told Xinhua on Saturday.Tang Geshi, a scientist with the Beijing Aerospace Control Center (BACC), said that the center will order the satellite to apply the first break at about 10:00 on Monday with no more planned orbital corrections.BACC carried out an orbital correction of Chang'e-1 on Friday, about nine days after its launch. "The correction has made the satellite run accurately in the transforming orbit heading to the moon, and another correction planned on November 4 will be unnecessary," Tang said.The Chang'e-1 lunar probe has been flying at a speed of 500-meter per second to the space where the moon's gravity could capture it.It has completed four orbital transforms and one halfway correction and is expected to enter the moon orbit on November 5.China's first lunar probe, Chang'e-1, named after a fairy-tale Chinese goddess who flew to the moon, blasted off on a Long March 3A carrier rocket on Oct. 24 from the Xichang Satellite Launch Center in southwestern Sichuan Province.

Joseph Li Shan was ordained on Friday as the new Catholic bishop of Beijing, filling the vacancy left by the late Bishop Michael Fu Tieshan who passed away in April.Father Li Shan, the new Catholic bishop of Beijing, walks out of the Southern Catholic Church following the appointment ceremony in Beijing, September 21, 2007. [Reuters]Li, 42, was appointed to the influential post at a ceremony in the city's 400-year-old Cathedral of the Immaculate Conception at Xuanwumen, Xicheng District in Beijing.The ceremony began with a procession of seminarians, nuns, priests and bishops, including ordaining prelate John Fang Xingyao from Linyi Diocese in East China's Shandong Province, and bishops from other major dioceses in China, who were serving as coordinating prelates.During the ceremony, Li took a traditional oath of service to the church, which has 50,000 followers in Beijing.He also promised to "lead all the priests, seminarians and nuns of this diocese in adhering to the nation's Constitution and maintaining national unification and social stability".Representatives from the Chinese Catholic Patriotic Association and the Bishops' Conference of the Chinese Catholic Church, as well as more than 70 priests and more than 1,000 worshippers attended the ceremony.Proceedings were broadcast to those outside via loudspeaker and closed-circuit television.Overseas media reported earlier that Vatican Secretary of State Cardinal Tarcisio Bertone described Father Li as a "good and qualified" candidate after his election by the Beijing diocese in July."We welcome the attitude of the Vatican. It signals progress in our relationship," Liu Bainian, vice-president of the Chinese Catholic Patriotic Association, said.Li was elected bishop-designate by an overwhelming majority over three competitors by priests and nuns of the Beijing diocese and representatives of Church followers on July 16, after his predecessor Michael Fu Tieshan passed away on April 20.Born in 1965, Li, who used to be a priest at Beijing's St Joseph's Church in the capital's Wangfujing commercial area, graduated from the Chinese Catholic Academy of Theology and Philosophy.He was ordained as a priest by Bishop Fu 1989.You Suzhen, a 75-year-old Catholic, said the new bishop was well liked in the diocese, and had rich experience as an administrator, academic and parish priest."I am confident he will be a good successor to Bishop Fu," You said."I'm sure he'll do a great job in uniting and leading us," Sun Xiang'en, a Beijing priest who helped train Li as a seminarian, said.Li was the second bishop ordained this year, after 40-year-old Paul Xiao Zejiang was ordained as coadjutor - the designated successor to the current Bishop Anicetus Wang Chongyi - in Guizhou Diocese earlier this month.Liu said the Catholic body has so far received six applications to fill vacant bishoprics in Guizhou, Guangzhou, Yichang, Beijing, Ningxia and Hohhot. The Chinese mainland has 5 million Catholics under 97 dioceses.

  

BEIJING -- The Chinese government on Sunday promulgated a revised decree to strike the activities of driving up prices through hoarding or cheating.The revision was made on the basis of regulations passed in 1999 and amended in February 2006 by the State Council.The new decree, effective as of Sunday, raises the maximum fine to 1 million yuan(US,000), which almost triples the sum in the old regulations, for those who manipulate market prices and ignore the prices advised by the government under emergencies.Commercial associations which deliberately spread rumors on price information can be fined at a maximum of 500,000 yuan. Those who severely violate the decree may have their legal certificates revoked.The State Council and local governments can set profit ratios or price ceilings for key items of goods and services when prices rise too sharp, according to the decree.

  

The Ministry of Agriculture on Monday confirmed a bird flu outbreak in South China's Guangzhou, which began with the mass deaths of ducks on September 5.The outbreak was confirmed as a sub-type of H5N1 bird flu by the National Avian Influenza Reference Laboratory, according to the ministry.It said 36,130 ducks had been culled as of September 17, after farmers in Sixian Village and Xinzao Township in the Panyu district of Guangzhou reported the deaths of their ducks on September 5.The agriculture ministry and the Guangdong provincial government immediately implemented an emergency plan to deal with the outbreak and the ministry said the outbreak has been brought under control.It also said no further deaths of fowl have been reported in the Panyu district or nearby areas.The last reported case of H5N1 bird flu in China occurred on May 19 at Shijiping Village in Yiyang City of Hunan Province, which killed more than 11,000 poultry with another 52,800 birds culled.China has reported a total of 25 human cases of bird flu since 2003, which have resulted in 16 deaths.
