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, Feb.1 (Xinhua) -- Chinese Vice President Xi Jinping on Monday urged all localities and departments to earnestly summarize experiences of the study and implementation of the Scientific Outlook on Development and make full use of its positive outcomes.Xi, also a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, made the remarks when he chaired a seminar held Monday in Beijing on the sum-up of the study and implementation of the theory, which emphasized the well-being of people and comprehensive, coordinated and sustainable development. Chinese Vice President Xi Jinping (C), who is also a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, addresses at a seminar in Beijing, capital of China, Feb. 1, 2010. Xi Jinping urged all localities and departments to earnestly summarize experiences of the study and implementation of the Scientific Outlook on Development and make full use of its positive outcomes in the seminar.He called for efforts to continue the study and research on the scientific outlook on development and well implement the theory, so as to accumulate new experiences.The CPC launched the campaign to study and implement the theory in September 2008, embracing a wide participation of more than 75 million CPC members.The campaign was scheduled to end at the end of this month, but Xi said, the implementation of the theory was a long-term mission and must be continued.

BEIJING, Jan. 8 (Xinhua) -- The move by the United States of selling arms to Taiwan brings chilly air to the warming China-U.S. relationship as well as military exchanges.The U.S. government on Friday announced the plans to sell a package of arms to Taiwan, which include Patriot missiles, Black Hawk helicopters and minesweepers. China immediately expressed strong indignation about the sale after the U.S. government notified the U.S. Congress of the plans.China slammed the U.S. move, pointing out it has violated the three Sino-US joint communiques, especially the principles established in the Joint Communique on Aug. 17, 1982, which stated that the U.S. would not seek to carry out a long-term policy of arms sales to Taiwan, and intended to gradually reduce arms sale.According to a press release of the Foreign Ministry, China has decided to partially halt the exchange programs between the militaries of the two countries, as well as the vice-ministerial consultation on strategic security, arms control and anti-proliferation, which was originally scheduled to be held soon.The two militaries had been expected to launch more exchanges in 2010, which include U.S. Defense Secretary Robert Gates' visit to China and mutual visits of warships.Qian Lihua, director of the Defense Ministry's Foreign Affairs Office, on Saturday summoned the defense attache of the U.S. Embassy in Beijing to lodge a stern protest."We reserve the right of taking further actions," he noted.The U.S. move cast a shadow over the military ties between China and the Untied States, which have seen a warming trend since U.S. President Barack Obama took office.The two countries held the latest round of defense consultations in Beijing in June, which were suspended for 18 months after the then outgoing Bush administration announced a 6.5-billion-U.S.-dollar arms package for Taiwan.At the first U.S.-China Strategic and Economic Dialogue held in Washington D.C. in July, the two countries agreed to expand military exchanges at various levels.Vice Chairman of China's Central Military Commission (CMC) Xu Caihou visited the United States from Oct. 24 to Nov. 3, the first senior Chinese military leader to visit the country since Obama assumed the presidency.These hard-won rising military exchanges resulted from consensus reached by the two heads of state on a sound and healthy development of bilateral ties, but at the same time they require cautiously handling of the sensitive issues like arms sale to Taiwan, the first and foremost obstacle of military ties.When U.S. President Barack Obama visited Beijing in November, China and the United States issued a joint statement, pledging that the two countries would "take concrete steps" to advance "sustained and reliable" military-to-military relations."I am very pleased with the reduction of tensions and improvement of the cross-strait relations," said Obama during a dialogue with Chinese youth in Shanghai.However, the arms sale deal apparently runs counter to the commitments the U.S. side have made.As one of the most important bilateral relationships in the world, a sound China-U.S. relationship not only conforms to the fundamental interests of the two peoples, but is also conducive to peace, stability and prosperity in the Asia-Pacific region and the world at large.Now the U.S. side should take the responsibility for the halt of military exchanges between the two countries, which may subsequently deal a blow to bilateral ties.

BRUSSELS, March 22 (Xinhua) -- China welcomes the latest document issued by the European Union (EU) on climate change, but insists that the EU should raise its emission cut target to 30 percent by 2020, a visiting Chinese official said on Monday.Su Wei,chief negotiator of China for climate change talks in Copenhagen, told a press briefing here that China welcomed the communication the EU issued in earlier March,which elaborated the bloc's standpoints on climate change for the first time following the Copenhagen talks in December."China welcomed in general the EU's latest positions," which among others reaffirmed the principle of "common but differentiated responsibilities" undertaken by developing and developed countries in dealing with climate change, the Chinese official said.In the communication issued on March 9, the EU expresses its willingness to continue to play a leading role in fighting against climate change and reaffirms its commitment to reduce its greenhouse gases emissions by 20 percent by 2020 and to increase this reduction to 30 percent if "the conditions are right."However, Su told reporters that EU should and could raise its emission cut target to 30 percent by 2020 on the basis of 1990 if the bloc wanted to play a leading role in dealing with climate change.The move would put more pressure on the United States to put forward ambitious goals, the chief negotiator said.Su said he was visiting the EU headquarters with a Chinese delegation led by Xie Zhenhua, vice minister of the National Development and Reform Commission, to exchange views with his EU counterparts on climate change.China and the EU shared many common goals and interests, the two sides should work together to boost international negotiations on climate change, he said.World leaders are scheduled to meet later this year in the Mexican resort town of Cancun for another go at inking a legally- binding global accord on emission reductions after 2012.Su said that China hoped the meeting in Cancun can achieve positive and meaningful results and make further progress on the basis of the Copenhagen talks.
