China's production of natural gas rose 23.1 percent last year, faster than in 2006, to 69.31 billion cubic meters as the country used more "clean" energy, an industry association said.In 2006, output jumped 19.2 percent to 58.55 billion cubic meters, the China Petroleum and Chemical Industry Association (CPCIA) said. It also said that output would likely hit 76 billion cubic meters this year. China used 55.6 billion cubic meters of gas in 2006, an increase of 21.6 percent from a year earlier, according to statistics from BP.China has set a target of raising the proportion of natural gas in its total energy consumption to 5.3 percent in 2010 from 2.8 percent in 2005, amid efforts to curb pollution. Coal now accounts for about 70 percent of total energy consumption.The expansion of the natural gas infrastructure, including pipelines, reflected the rapid increases in output and consumption, the CPCIA said.China plans to start building a second east-west gas pipeline this year. The first such pipeline went into commercial operation in 2004.The new pipeline is scheduled to become operational in 2010 and will have a designed annual transport capacity of 30 billion cubic meters. It will mainly move natural gas from Central Asia to the Yangtze and Pearl River Deltas, the country's two most developed regions.Construction on another pipeline, which will link the Puguang Gas Field in the southwestern province of Sichuan, one of the country's largest, with the Yangtze River Delta, started last August.

DALLAS -- Several leading US airlines have asked federal regulators for the right to operate new nonstop flights between the United States and China beginning in March 2009.American, the largest US carrier, said it applied Monday for a route from Chicago's O'Hare Airport to Beijing. A similar bid failed several months ago, partly because American's management and pilots couldn't agree on work rules for the flights.Continental applied Monday to fly between Newark, N.J., and Shanghai. The Houston-based airline said its flights would serve the financial hub of New York and a large Chinese-American population in the area. US Airways said it is seeking to offer nonstop service between its Philadelphia hub and Beijing, China. Delta Air Lines Inc. asked to fly from Atlanta to Beijing and Shanghai; and Northwest Airlines Corp. filed to offer service between Detroit and the same two Chinese cities. UAL Corp.'s United Airlines proposed to fly between San Francisco and Guangzhou starting in 2008, and between Los Angeles and Shanghai in 2009. Air service between the two countries is restricted by agreements between the two governments. US airlines eager to tap the growing Chinese market must apply to the Department of Transportation for new routes. In the competition for Chinese routes, US airlines gather support from politicians and customers to sell their proposals to federal regulators. For example, American, a unit of Fort Worth-based AMR Corp., boasted support from four US senators and three governors. Schwarzenegger favors proposal for non-stop flights to China California Governor Arnold Schwarzenegger said Tuesday that he favored a proposal for non-stop air services to China from two major Californian cities. Schwarzenegger made the remarks after United Airlines submitted an application to the US Department of Transportation Monday to add daily, non-stop services from San Francisco and Los Angeles to China in 2008 and 2009. "China's more than 1 billion citizens represent an important market for Californian products and services," Schwarzenegger said in a statement e-mailed to Xinhua. "United Airlines' proposal to add a daily, non-stop service between our state and China is a great opportunity to promote California tourism and pump up our state's economy," said the governor. "Direct flights between California and China will only have a positive impact on our state and I look forward to working with United Airlines in the future as we continue to strengthen our economic ties with this important Pacific Rim partner," he added. United Airlines' application proposes a non-stop service between San Francisco and Guangzhou in 2008, and a daily non-stop service between Los Angeles and Shanghai in 2009. In 2006, exports from California to China totaled almost 10 billion dollars, up from 5.5 billion dollars in 2003 when the governor took office, according to the statement. California is the number one US state in terms of total exports to China and the top exports include computers and electronic products, waste and scrap materials, transportation equipment and heavy machinery.

China has sent rescue ships to search for a cargo vessel missing in the East China Sea with 17 Russian crew on board.The China Maritime Search and Rescue Center said on Friday it launched a search and rescue emergency plan soon after a rescue center in Russia's far east informed it of the missing boat on Thursday.The Cambodia-registered ship went missing on its way from Japan to Hong Kong.The vessel failed to arrive in Hong Kong on Thursday as scheduled, and the last radio contact was made with the ship on Sunday, when it was 212 sea miles (391 km) east of Shanghai.Russian rescue officials then informed rescue centers in China, Japan and South Korea of the Captain Uskov's disappearance."Our rescue ships have started searching," Zhai Jiugang, a senior official with China's search and rescue center, said.Vessels sailing in the East China Sea have also been informed by the center's branches in Shandong and Shanghai of the disappearance of the ship, and were asked to assist in the search, he said.The center is also using maritime satellites to help search for the vessel. But by Friday afternoon, there was "no clue about the missing boat, and we will continue to search", he said.The boat, with a cargo capacity of 5,200 metric tons, was built in Japan in 1982. It flew a Soviet flag and was later sold to a private shipping company and registered in Cambodia.

NEW YORK - The overheating of the Chinese stock market is a structural problem that will be resolved by developing more financial products and cracking down on illegal activities, a Chinese securities regulatory official said Thursday. Hu Bing, deputy director-general of the market supervision department at the China Securities Regulatory Commission, said at a conference in New York that authorities are seeking to roll out more products to broaden investors' options, such as real estate investment trusts, or REITs, as well as listed infrastructure funds. Other eventual offerings will include derivatives products such as stock-index futures and warrants. These products will be launched "when conditions are ready," Hu said at a China Investment Forum sponsored by Merrill Lynch and Institutional Investor. He said he couldn't provide a clearer timeline for when those products would be ready. Hu acknowledged a "liquidity surplus problem" that is contributing to the overheating of the Chinese stock market and noted that hot-money inflows coming in through illegal channels are exacerbating the problem. Tackling the liquidity issue is a long-term project that "cannot be resolved just by (raising) the interest rate," Hu said. "So the structural problem has to be resolved using structural measures." Earlier this week, the Chinese government tripled its stamp tax on stock trades in an effort to rein in the equity market. The Shanghai Composite Index more than doubled in 2006 and is still up around 50 percent so far in 2007. Hu said China's capital markets are still young and face a "golden opportunity" to develop their depth and breadth. The majority of individual investors rely on rumors or inside information to make their decisions, leading to speculative gains in stocks, he said. Hu said authorities are stepping up efforts to crack down on insider trading, "but because this is a transitioning society in an emerging market, it will take a long time."
