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 22 (Xinhua) -- Senior Chinese leader Zhou Yongkang has urged law enforcement departments at all levels to ensure their work practices are just and incorrupt to better solve social conflicts and uphold justice."Currently, our country is experiencing a period when social conflicts are prominent and more and more cases have emerged in the judicial field," Zhou told a plenary meeting for the Political and Legislative Affairs Committee of the CPC Central Committee here Monday."More people are expecting to protect their own rights through judicial channels and they also have a higher requirement for just law enforcement," said Zhou, also a member of the Standing Committee of the Political Bureau of the CPC Central Committee."However, many people's ideas, abilities and working styles in the judiciary who enforced the law still left much to be desired," he said, adding that many proposals raised during the just-concluded annual parliamentary and political advisory sessions were about law enforcement.Zhou urged related departments at all levels to "carefully" study these advices and proposals and investigate and correct mistakes.

BEIJING, Feb. 24 (Xinhua) -- Chinese military and international relations experts on Wednesday said that a recent Pentagon report playing down Taiwan's aerial combat capability was a front for more advanced arms sales to the island, which would seriously violate a Sino-U.S. agreement that Washington endorsed 28 years ago. "Any further arms sales, especially if the U.S. sells F-16 fighters to Taiwan, would increase already strained tensions with China," Prof. Tan Kaijia with the National Defense University of the People's Liberation Army told Xinhua. The report delivered by the Defense Intelligence Agency of the U.S. Department of Defense to the Congress has stressed that many of Taiwan's 400 active combat aircraft were not operationally capable due their age and maintenance problems. It also specified that Taiwan's 60 U.S.-made F-5 fighters have reached the end of their operating life and some of the island's F-16 A/B jet fighters needed improvement to increase combat effectiveness. The Pentagon's report came as Taiwan continued to voice its need for advanced U.S. weaponry such as 66 F-16 C/Ds, a substantial improvement model on Taiwan's current F-16 A/Bs. But the U.S. side excluded the fighters from the latest arms sale package. According to media reports, Taiwan currently operates 60 U.S.-made F-5 fighters, 148 F-16 A/Bs, 56 French-made Mirage 2000-5 fighter jets and 126 locally produced Indigenous Defense Fighter (IDF) aircraft. "If the U.S. equips Taiwan with new F-16s, replacing the second-generation F-5s, it would significantly increase the island's aerial combat effectiveness for F-16's compatibility to other U.S.-made weapon systems such as airborne early warning and control aircraft through Link-16 Multifunctional Information Distribution System," said Prof. Tan. According to the Communique jointly issued by the Chinese and U.S. governments on Aug. 17, 1982, the U.S. side states that "its arms sales to Taiwan will not exceed, either in qualitative or in quantitative terms, the level of those supplied in recent years since the establishment of diplomatic relations between the U.S. and China." "Comprehensive performance of the F-16s is far beyond that of the F-5s and the qualitative parameters of the F-16 C/Ds also exceed those of the F-16 A/Bs," said Tan. Selling such arms would "be an overt offense" against the Aug. 17 Communique, and promoting such a move by an elaborate report would not give any justification for the U.S. since the F-16 C/Ds would not be considered as a defensive weapon in any case, he said. Guo Zhenyuan, a researcher with the prominent thinktank China Institute of International Studies, told Xinhua that previous U.S. arms sales to Taiwan were covered by the front of "providing Taiwan with arms of a defensive character" to ease the backlash to the bilateral relationship from the Chinese side. "The U.S. side should know that the sooner it stops selling arms to Taiwan, the more willing China would be to work with it on global and regional issues," Prof. Jin Canrong with Renmin University of China said.
