BEIJING, Jan. 21 (Xinhua) -- A senior official with China's central bank Wednesday called on lenders to balance their lending this year and to avoid abrupt loan fluctuations.The People's Bank of China (PBOC) will continue to optimize the lending structure and properly manage the pace of credit growth while ensuring sufficient loans for economic recovery, said Zhang Tao, head of the bank's financial survey and statistics department.The PBOC will continue its moderately loose monetary policy this year, he added.Premier Wen Jiabao on Tuesday urged the government to optimize credit structure and maintain a proper pace of credit supply to guard against financial risks.China's top banking regulator Liu Mingkang told the Asia Financial Forum held in Hong Kong Wednesday that China's overall credit growth will be scaled down to 7.5 trillion yuan (1.1 trillion U.S.dollars) in 2010, compared with last year's lending spree of 9.59 trillion yuan.To help soak up extra cash flow, the central bank raised the reserve requirements on banks by 0.5 percentage points on Monday, the first increase in 18 months, which analysts forecast would help freeze 250 billion yuan of liquidity.

BEIJING, March 16 (Xinhua)-- The China "Summer Davos" summit, due to be held in September in the north China city of Tianjin, will again focus on sustainability and the green economy, said Andre Schneider, managing director of the World Economic Forum (WEF), Tuesday.The detailed agenda would be designed to meet the changing new growth context with more discussion of new business models and technical innovations, Schneider said in a press briefing in Beijing.The "Summer Davos" 2010, or the fourth Annual Meeting of the New Champions, would be a continuation of the third-round meeting last year, which had focused on the way out of crisis, said Schneider.With the theme, "Driving Growth Through Sustainability," this year's summit, from Sept. 13 to 15, is expected to attract more than 1,500 participants, including business executives, politicians, economists and scientists from about 90 countries.On the global economy picture, Schneider said the deep financial and structural roots of the "Great Recession" made it difficult to predict the shape of future growth.Schneider said the future also remained unclear for advanced economies, which the Organization for Economic Cooperation and Development forecast, would see a possible 10-percent unemployment rate in the second half of this year.Though the emerging and developing economies accounted for almost 50 percent of global GDP, their growth was not decoupled from the rest of the world, said Schneider.

BEIJING, Feb. 7 (Xinhua) -- China and Russia would strengthen coordination to better implement the regional cooperation program approved by state leaders last year, officials from the two countries said here on Sunday.The statement was made by Zhang Guobao, head of the National Energy Administration and vice minister of the National Development and Reform Commission, and representatives of the Russian government, at the China-Russian regional cooperation symposium.In September 2009, Chinese President Hu Jintao and his Russian counterpart Dmitry Medvedev approved the cooperation program between northeast China and Russia's far east and east Siberian region.Zhang said the cooperation program, covering many fields, included more than 300 key projects in local cooperation and infrastructure construction and transformation.The symposium is the first bilateral meeting aimed at promoting China-Russian regional cooperation since the approval of the cooperation program.

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.
