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.

Washington - China is on course to catch up with the United States and join the front ranks of world economic powers, but that is little cause for concern even among Americans, a global survey said Monday. Most respondents in 13 countries agreed it was "likely that someday China's economy will grow to be as large as the US economy," according to the opinion poll by the Chicago Council on Global Affairs and WorldPublicOpinion.org. "What is particularly striking is that despite the tectonic significance of China catching up with the US, overall the world public's response is low key -- almost philosophical," said Steven Kull, editor of WorldPublicOpinion.org. But the poll showed there is also distrust of China to "act responsibly" in world affairs.  In no country was there a majority who felt that China's economic rise would be mostly negative, but that was not because China is particularly trusted, the pollsters said. Majorities in 10 out of 15 countries said they did not trust China "to act responsibly in the world." But the same number also said they distrusted the United States. "Though people are not threatened by the rise of China, they do not appear to be assuming that it will be a new benign world leader," Kull said. "They seem to have a clear-eyed view that China is largely acting on its own interests." The Chinese themselves are among the more skeptical populations, with only half saying that their economy will catch up with the United States'. Among Americans, the percentage was 60 percent. Only in India and the Philippines did a plurality of respondents say the United States would always remain a bigger economy than China. The highest level of concern about the implications of China's economic march was in the United States, where one in three is worried. But 54 percent of Americans said that its rise would be "neither positive nor negative" while one in 10 said it would be mostly positive. Only in Iran did a majority -- 60 percent -- say that it would be "mostly positive for China to catch up." The survey included 18 countries: Australia, Argentina, Armenia, China, France, India, Iran, Israel, Mexico, Peru, the Philippines, Poland, Russia, South Korea, Thailand, Ukraine, and the United States, plus the Palestinian territories. Not every question of the poll was asked in each country, so that the results for some questions covered less than 18 countries.

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. 

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.
