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.

BEIJING - China is trying to improve the role of the country's more than 2,400 museums to make them more accessible to the public, according to an ongoing national conference attended by directors of provincial cultural relics departments.The museums, which are sponsored by the government, institutions or individuals, hold nearly 10,000 exhibitions on different themes annually. In all, they received about 150 million visitors each year.A big boost, thanks to government efforts, is that more and more Chinese museums have stopped its long-time practice of selling tickets to visitors.Increasingly, critics had complained that the expensive charges collected by educational and cultural institutions had become a big financial burden on Chinese families.To date, more than 1,000 museums and memorial institutions have been officially made educational bases for patriotism and popular science. They received 32 million underage visitors annually.

Shanghai -- British Prime Minister Gordon Brown hailed a new era of environmental cooperation between Britain and China on Saturday and called for a renewed drive for a world trade deal.Brown visited a highly efficient gas-fired power station in Beijing and studied the plans for an environmentally friendly town to be built near Shanghai to underline his keenness to cooperate with China on fighting global warming."We now enter this new era of environmental cooperation," Brown told a news conference in Shanghai after listening to a presentation on Dongtan, billed as the world's first eco-city.Construction is due to start early this year at Dongtan, designed by British engineering firm Arup. It will use renewable energy and will not allow gasoline-fuelled cars.It is the first of a number of low-carbon eco-towns being planned by both Britain and China.Brown, who flies to India on Sunday, pleaded for progress in slow-moving talks on a new world trade agreement."I would like the talks which have now been stalled for some months to resume," he said.All sides would have to compromise to reach a deal but the differences can be bridged, Brown said."In the next few weeks I will ... talk to all the potential players as I've done with the Chinese government, as I will do tomorrow with the Indian government, (about) the importance of us moving forward to a trade agreement as soon as possible."

There is perhaps no better time to savor the charm of Tian'anmen Square than during the week-long National Day holiday.Two girls pose with small national flags on Tian'anmen Square September 30, 2007, the eve of the week-long National Day holiday. [Xinhua] Stretching in front of the Forbidden City, it is ablaze with the color of 400,000 pots of flowers in full bloom.This year's major events can be seen at the city's center. Looking east are scale models of the Acropolis in Athens, the Great Wall, and a 9.8-meter Olympic torch, which represents the torch relay from Greece to China.To the south can be seen models of the Temple of Heaven and major scenes marking key events in the history of the Communist Party of China (CPC) to welcome the 17th National Congress of the CPC which starts on October 15.A big fountain sprouts water as high as 60 meters in the middle of the square surrounded by a bed of flowers."The square is always the best place to experience the festive atmosphere of the National Day," Deng Chuanmei, 48, a visitor from Jiangsu Province, said.Wei Liqing, a Beijing resident, said she has taken photos and videos at the square every National Day holiday since 1992. "I want to record the pace and growth of our country," she said.Work on the decorations and flower displays started about 25 days ago, and was carried out at night to avoid disrupting tourists and traffic, Zhou Jianping, an official with the Beijing gardening and forestation bureau, said.He said this year's decorations include 130 kinds of flowers, of which more than 20 will also be on display during the next year's Olympic Games. If weather permits, the flowers will be shown until the end of the month.The national flag raising ceremony will also be a major attraction. At dawn today, an estimated 200,000 people will gather at Tian'anmen Square to watch the event.The capital's tourism administration bureau has predicted that about 1.7 million people will visit the capital during the seven-day holiday.

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.
