CHANGSHA/HARBIN, Feb. 12 (Xinhua) -- As Chinese people are embracing the arrival of the Year of Tiger on Saturday, zoologists are worried about the survival of South China Tigers as the endangered species are facing a serious problem of inbreeding.No traces of the tigers have been found in the last decade, they said.The number of captive South China tigers (Panthera tigris amoyenesis) rose to 92 in 2009 from 60 in 2007 but all the tigers were the offsprings of six wild South China tigers which were caught more than 40 years ago, said Deng Xuejian, a professor with the Department of Biology of Hunan Normal University, based in Changsha, capital of central China's Hunan Province."The inbreeding may lead to genetic freaks, low survival rates and poor physical makeup," Deng said.All the genes have come from two male and four female tigers, which had lead to highly identical genes in the offspring, Deng said."The situation may reduce the genetic diversity and cause degradation or even the extinction of the species," he said.The tigers would lose genetic diversity if their genes were too similar, said Ma Zaiyu, president of veterinary hospital of Changsha Zoo."The number of the members of a species should be at least 1,000 to maintain the stability of the species," Ma said.Zoologists estimated the number of wild South China tigers could have been less than 30 in the 1990s. The remaining wild tigers are presumed to live in the remote areas of Guangdong, Hunan, Fujian and Jiangxi provinces, Deng Xuejian said.Based on analysis of relevant date combining field investigation, Deng estimated the number of wild South China tigers could be less than 10.No traces of wild South China tigers were reported in Hunan in the last two years, said Zhou Shuhuai, director of wildlife protection section of the Hunan provincial forestry bureau."The number is limited and the tigers scatter in different areas, which make it difficult for natural breeding between wild tigers," said Huang Gongqing, a tiger expert at South China Tiger Breeding Base in Suzhou, a city of east China's Jiangsu Province."The extinction of the wild tigers will happen sooner or later," Huang warned.Some experts have said that there may be already no wild South China tigers. "However, we cannot know as the animal is very difficult to trace," Deng said.Ma Zaiyu said to avoid extinction of the species, more captive tigers should be bred, and some genes might be recovered when the population reaches 1,000, while Deng suggested continuous search for wild tigers to enrich the captive tigers' genes.The situation is much better for the Siberian tigers (panthera tigris altaica) in northeast China as the number of the wild ones is quite stable, experts said.The number maintains at around 20 in China, among which 10 to 14 are in Heilongjiang Province and eight to ten are in Jilin Province, said Sun Haiyi, deputy director of Heilongjiang Wildlife Institute"But no more young tigers under one year old have been discovered in the past two years. The reason might be the number of female tigers are less than the males and the animals are relatively isolated by the mountains," Sun said.China established a breeding base for the Siberian tigers in Heilongjiang in 1986 and the number of captive tigers has increased from eight to current more than 800, Sun said.Experts called for more efforts to protect the habitats of the tigers for the purpose of protection and re-wilding of the tigers.

BEIJING, March 9 (Xinhua) -- China would step up work to monitor non-banking financing, said the China Banking Regulatory Commission (CBRC) Tuesday in a statement on its web-site.More focus would be put on businesses in connection with trust companies and the real estate sector to prevent banks from using non-banking financing to circumvent policies, said Liu Mingkang, chairman of the CBRC.The 2010 government loan target is 7.5 trillion yuan (1.10 trillion U.S. dollars). But in January alone, banks extended 1.39 trillion yuan in new loans -- 18.53 percent of the full-year target.More work should be done to improve risk management capacity to achieve sustainable development of the non-banking financing sector, Liu said.Non-banking financial institutions under the CBRC supervision include trust companies, finance companies, financial leasing companies, auto financing companies and money brokers.

BEIJING, Feb. 1 (Xinhua) -- The Purchasing Managers' Index (PMI) of China's manufacturing sector stood at 55.8 percent in January, down 0.8 percentage points from the previous month, the China Federation of Logistics and Purchasing said on Monday.

BEIJING, Jan. 30 (Xinhua) -- China Unicom, the country's second largest telecom operator, said Saturday its net profit might have dropped by more than 50 percent in 2009, as the one-time gain from the sale of a mobile business laid a higher comparison basis for 2008.China Unicom, in October 2008, sold its Code Division Multiple Access (CDMA) business and related assets to China Telecom, the largest fixed line service provider of the country, which substantially increased the profits of the company in 2008.The company said in a statement filed to the Shanghai Stock Exchange that its profit was also affected by the high costs for its new Wideband-CDMA operations.

WASHINGTON, Feb. 27 (Xinhua) -- China remains the largest foreign holder of U.S. Treasury securities as at the end of December, the U.S. media reported on Saturday.The report quoted the new government data as saying that China held 894.8 billion dollars in Treasury securities at the end of December, more than 755 billion dollars that had been previously estimated.But the new report also showed China trimmed its holdings of U. S. debt by 34.2 billion U.S. dollars in December.The U.S. Treasury reported on Feb. 16 that Japan surpassed China as the largest holder of U.S. Treasury securities in December. But the new estimate said Japan, now back in second place, held 765.7 billion dollars in December.Japan had been the largest holder of U.S. Treasury securities until China gained that distinction in 2008."Purchase of Treasuries by China would reflect only purchases by an entity in China from an entity based in the U.S.," Stone & McCarthy Research Associates said in a recent client note."The Data would not pick up purchases done on behalf of Chinese investors by dealers in the U.K or Hong Kong, for example, nor would it pick up purchases of Treasuries by investors in China from investors based outside of the U.S.," it added.China defended its move to reduce its holdings of U.S. Treasury securities, saying the United States should take steps to promote confidence in U.S. dollar .Last week, when responding to questions on China's sale of U.S. Treasury securities in December, China's Foreign Ministry spokesman Qin Gang said the issue should be viewed from two perspectives.He said on the one hand, China always followed the principle of "ensuring safety, liquidity and good value" in managing its foreign exchange reserve. And when it came to how much and when China buys the bonds, the decision should be made taking into account the market and China's need, so as to realize rational deployment of China's foreign exchange property, he said.And on the other hand, the United States should take concrete steps to beef up the international market's confidence in the U.S. dollar, Qin said.The way to view the issue was similar to doing business, he said.
