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."

People in the southern city of Guangzhou appear to be suffering mental problems at ever younger ages as they struggle to adapt to life outside the home and school, a source with the local health authority said.There are currently 43,803 registered cases of mental illness in the city. Up to 40 percent of them are between 16 and 25 years old, according to the Guangzhou health bureau."A decade ago, most people with mental illnesses were between 18 and 30 years old. But now they are five years younger," Zhao Zhenghuan, director of the Guangzhou Brain Hospital, said.Zhao attributed the situation to young people's "relatively poor social adaptability.""Children from single-child families receive a lot of care at home and school, but when they leave home and school, they find it hard to adapt to life. They easily develop mental problems such as anxiety and depression," Zhao said.Pan Jiyang, a psychologist with the first Affiliated Hospital of Jinan University in Guangzhou, Thursday called for "early treatment and mental education" for teenagers who are mentally ill.Not seeking helpPan said some 80 percent of people who suffer from mental illness do not seek help after their conditions are diagnosed."Delayed treatment at the early stage will lead to more serious conditions. Most parents just cannot believe their kids have developed mental problems," Pan said, adding that young mental patients could attempt suicide or commit crimes if they are not treated well.In one case, a 21-year-old student believed to be suffering from a mental illness stabbed six of his classmates at an IT college in Zhuhai, Guangdong Province, last month.To better cope with the situation, the Guangzhou Teenager Service Center, a psychological treatment center affiliated to the Guangzhou Communist Youth League, has employed eight psychological experts.The experts will work with people suffering from mental illness through a hotline (12355).Meanwhile, nearly 100 psychologists will soon be deployed in communities, schools and work units to promote mental health among young people.

Nearly one out of three people in Beijing belongs to the mobile population, according to the capital's population and family planning commission.Workers stand on a temporary dormitory at the Central Business District in Beijing September 2, 2007. China's 120 million migrant workers, the young generation in particular, are demanding higher wages and a better working environment, the Labour Ministry said. [Agencies]The municipality's mobile population reached 5.4 million in October, accounting for nearly 30 percent of the total, the commission's deputy director Li Yunli said.More than 80 percent of the capital's mobile population belongs to the China-unique category of rural migrant workers, Li told a conference on population in Beijing on Monday. The remainder is mostly made up of people visiting for less than a month.She added that migrant workers would comprise the vast majority of both the capital's and the nation's mobile population for a long time to come. Currently, the national mobile population stands at 150 million.The most recent influx of migrant workers boosted the capital's population to about 17.4 million by October, signaling Beijing's population would likely exceed its threshold of 18 million earlier than previous forecasts, Li said.The total population would continue to grow in Beijing over the next five or 10 years, Li said, and "that would further strain scarce resources, including land, water and energy".Previous research has suggested that accommodating more than 14 million residents would exceed Beijing's food- and water-supply capacities.More than 130,000 people were born in Beijing in 2007 as of October, and more than one-third of them were born to migrant families, Li said. And according to her, there would be even more births next year.This year, most of the capital's unplanned births were to migrant families, Li said."Family planning among migrant workers is crucial to China's overall family planning, and the construction of a new socialist countryside and a harmonious society," deputy director of the State Population and Family Planning Commission Wang Guoqing was quoted as saying by Xinhua news agency earlier.In addition, most of the migrant workers in Beijing work labor-intensive jobs in fields such as manufacturing, home furnishing, catering, cleaning and domestic services.Most migrant workers received little education, with 60 percent of them dropping out after junior middle school mainly because of financial problems, Li explained.More than half of them earn less than 1,200 yuan (0) per month and live in poorly equipped rental rooms, Li added.Researcher with China Foundation for International and Strategic Studies Qin Xiaoying said that if migrant workers remain economically and socially marginalized, mental anguish could flourish among the demographic and threaten social stability.The commission urged governments at all levels to improve public services for the migrant population, protect their legal rights and interests, and reduce discrimination against them.

BEIJING - The National Grid of China said power could be restored partially within the day in the worst-hit region in central China's Hunan Province, ending the eight-day blackout caused by snow.Local residents buy candies for the upcoming Spring Festival in Chenzhou, Central China's Hunan Province, February 1, 2008. Power supply in Chenzhou City has been cut off during the past eight days, leaving thousands of households in dark and coldness. [Xinhua] "Many power facilities in Hunan were damaged due to repeated extreme weather changes," said Yin Jijun, deputy director of the international liaison department of the National Grid. "As the weather deteriorated again, the regional power grid, in particular the southern grid in the province, is facing acute challenges."A new round of snow started to hit central, south and east China regions on Friday, adding to the woes caused by previous snowfalls.Hunan is one of the hardest-hit areas for the past three weeks. Power supply in Chenzhou City has been cut off during the past eight days, leaving thousands of households in dark and coldness. Hengyang and Yongzhou cities also experienced blackouts in some areas.To address the situation, Yin said the National Grid is working all out to ensure security of the main power network in southern Hunan, especially in Chenzhou."We will strive to partially restore electricity supply in Chenzhou on Saturday," Yin said.

Yahoo co-founder Jerry Yang said on Wednesday that China is fertile ground for an online advertising exchange akin to the one the US Internet titan is buying. The comment was among insights Yang shared with more than 1,000 Chinese and US technology entrepreneurs gathered in the California city of Santa Clara to discuss opportunities and challenges presented by the meteoric growth of China's economy. US Internet giant Yahoo co-founder Jerry Yang during a presentation in a Tokyo hotel, March 2006. Yang said on Wednesday that China is fertile ground for an online advertising exchange akin to the one the US Internet titan is buying.[AFP] "I'm going to call Jack Ma up with this idea of an exchange for advertisers and ad buyers," Yang said, referring to the chairman of Chinese Internet company Alibaba.com. "The potential is huge." In August 2005, Yahoo invested one billion dollars for a 40 percent stake in Alibaba, which also agreed to run the Chinese operations of the US Internet giant. Yang said that as it neared its second anniversary, the Yahoo-Alibaba partnership has "some catching up to do" in the online search and portal business in China but that he expected a turnaround in a few years. "On the whole, we feel our move to partner with Alibaba so far looks like it's the right strategy," Yang said. "It is too early to tell whether we are successful or not." "The best strategy still seems to be Chinese and US companies sharing best practices ¡ª we all benefit." Yahoo is buying New York City-based online advertising exchange Right Media in a move to counter Google's move to acquire the DoubleClick Internet ad-targeting firm. The California online search titan, which owns 20 percent of Right Media, said it will acquire the remaining 80 percent of the company for 680 million dollars (500 million euros) in stock and cash. The ad exchange serves as a place where advertisers can easily "hook-up" with websites or online services that cater to desired customer demographics. While announcing on April 13 that it was buying New York-based DoubleClick for 3.1 billion dollars, Google revealed plans for the Internet ad tracking and targeting firm to create an open exchange similar to Right Media.
