BEIJING -- China may entirely switch to non-food materials such as cassva, sweet potato, sorgo and cellulose in producing ethanol fuel as a substitute for petroleum, said a government official. The country would approve no projects designed to produce ethanol fuel with food from now on, an official of the National Development and Reform Commission (NDRC) told a seminar on China's fuel ethanol development held in Beijing on Saturday. "Food-based ethanol fuel will not be the direction for China," said Xu Dingming, vice director of the Office of the National Energy Leading Group, who was also at the seminar. China has been trying to avoid occupation of arable land, consumption of large amount of grain and damages to the environment in developing the renewable energies. The current four enterprises engaged in producing corn-based ethanol would be asked to switch to non-food materials gradually, according to the NDRC official who declined to be named. The four enterprises in Jilin, Heilongjiang, Henan and Anhui have a combined production capacity of 1.02 million tons of corn-based ethanol per year. The country has become a big producer and consumer of ethanol fuel in the world after the United States, Brazil and European Union, according to the NDRC official. China Oil and Food Corporation (COFCO), the country's largest oil and food importer and exporter, would focus on sorgo in the production of non-food-based ethanol fuel, said Yu Xubo, president of COFCO at the seminar. COFCO, which owns the Heilongjiang enterprise and has a twenty-percent stake in the Anhui enterprise, aims to produce five million tons of ethanol fuel based on sorgo in the near future. COFCO is leading the way in developing cellulosic ethanol fuel under a cooperation agreement with Denmark-based Novozymes, which leads the world in researches into the key enzymes needed in large-scale production of cellulosic ethanol. The current cost for producing ethanol fuel from stalks of corn, which are discarded by farmers, is still too high. Novozymes is working on the commercialization of cellulosic ethanol both in the United States and China. "We are optimistic about China's prospect of making it work ahead of the US, as the cost of collecting the stalks of corn are much cheaper in China," said Steen Riisgaard, president and CEO of Novozymes. There is much opposition both in China and in the world to corn-based ethanol fuel, which is believed will lead to higher corn price.

The growth of the services sector should be accelerated and opened wider to private and foreign investors, the State Council has said. Market access for such sectors as telecommunications, railways and civil aviation - by far largely State-owned - will be increased and more competition encouraged to diversify investment, the Cabinet said in a document released yesterday. The country will establish an "open, fair and rule-based" market access system, according to the document, which urged local governments and departments to encourage foreign investment and improve the legal framework in the sector. Private investors are encouraged to "raise the proportion of non-State output in the national services industry". No domain should be off-limits as long as the law does not forbid the entry of non-State investors, the document said. The State Council said the services trade should be encouraged to change the foreign trade growth pattern, which comprises mainly exports of low-end manufactured goods. Some local governments were criticized for tilting toward heavy industries and ignoring the services sector, which made up 40.2 percent of China's gross domestic product (GDP) last year. It generally accounts for about 70 percent in developed economies.The sector is important for China as it makes efforts to change its economic growth pattern, reduce consumption of energy and resources and create jobs, the document said. Given those benefits, "developing the services sector is imperative for China," Liu Xiahui, an economist with the Chinese Academy of Social Sciences, told China Daily. "But for the moment, it still has to rely on the industrial sector to generate more tax revenues and achieve a high rate of economic growth." Liu said while the general services industry, such as the catering trade, has grown fast, many regions are not developed enough to accommodate high-end value-added services, such as finance. "We cannot ignore our economic reality." "But I do hope the country can make bigger strides in developing the services sector, which is in line with China's future needs," Liu added. As one of the steps, the State Council urged more input into sectors oriented toward people's livelihood, such as real estate, non-State nursing homes for the aged and culture. The cabinet put special emphasis on the services industry in rural areas, urging an increase in farmers' incomes and a relaxation of the urban household registration system.

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.

CAPE TOWN, South Africa - Central bank chiefs from the U.S., Europe and Japan warned Tuesday of the risks of the Chinese economy overheating, potentially adding to inflationary pressures in other countries. U.S. Federal Reserve Chairman Ben Bernanke and European Central Bank President Jean-Claude Trichet also urged Beijing to let its currency rise in value, saying it would benefit both China and the global economy. "A quick pace toward greater flexibility would be in China's interest and create more flexibility for monetary policy to address the potential overheating of their economy," Bernanke said in a satellite linkup with a banking conference in Cape Town. "We could all be better off, China on the one hand and the global economy on the other hand," echoed Trichet. Critics argue that China is keeping its currency artificially low, contributing to its massive trade surplus with other countries and undermining competitors' prices. Both Bernanke and Trichet conceded that the cheapness of Chinese products flooding world markets had helped reduce global inflation, although said this was balanced by China's huge appetite for fuel and raw materials -- which has contributed to higher oil prices. Overall, China's impact on global inflation was "modest," Bernanke said. China is one of the world's fastest-growing economies, and its expansion has had a ripple effect on prosperity in other countries and offset more modest growth rates in North America, Europe and Japan. Trichet said the current boom was "absolutely exceptional in the global economy," but warned that this could not last indefinitely. "Complacency would be the worst possible advice for all of us," he said. Japan, where growth is a sluggish 2 percent, is keeping a watchful eye on the new Asian giant. "We need to be mindful of the risk of overheating and we can't rule out some risk of inflation in the Chinese economy," said Toshihiko Fukui, governor of Japan's central bank. China is witnessing a stock market boom, with millions of first-time investors jumping into the market, tapping savings and retirement accounts and mortgaging homes to buy stocks. Authorities are worried that the new money is fueling a bubble in prices. Chinese stocks rebounded Tuesday in volatile trading after their sharpest one-day drop in three months a day earlier as strong buying by institutions offset selling by retail investors. The benchmark Shanghai Composite Index fell 8.3 percent on Monday -- the benchmark's sharpest decline since an 8.8 percent drop Feb. 27 triggered a global market sell-off.

SHANGHAI -- A train designed to run at a speed of 200 km per hour left east China's Shanghai for Suzhou early Wednesday morning, ushering in a high-speed era for the world's fastest growing economy. Brand new homemade high-speed trains CRH are seen at a railway station in Jinan, east China's Shandong Province, April 12, 2007. The CRH trains which could run at least 200km per hour, will serve on high speed routes between major cities after the sixth nationwide railway speedup from April 18. [Xinhua]Nationwide, 140 pairs of high-speed trains with a speed of 200 km per hour or a faster speed will begin to hit the railways on Wednesday. The number will increase to 257 by the end of this year. Numbered D460, the train left Shanghai at 5:38 a.m. and is expected to arrive in Suzhou 39 minutes later. Wednesday marks the the beginning of the sixth "speed boost" of Chinese railways, which has been hard-pressed to cope with the country's hunger for bigger transport capacity. Chinese railway officials said last year, China fulfilled a quarter of the world's total railway transport volume on railways accounting for only 6 percent of the world's total length. "The sixth speed lift will boost passenger capacity and cargo capacity by over 18 percent and over 12 percent respectively," said Hu Yadong, vice-minister of railways.
