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. 4 (Xinhua) -- Chinese Premier Wen Jiabao on Thursday urged to boost development of social undertakings and improvement of people's livelihoods while pushing forward the transformation of economic growth mode.Speaking to a seminar for provincial and ministerial level officials presided over by Vice Premier Li Keqiang and attended by Vice President Xi Jinping, Wen said development of science, education and culture was key to the transformation of China's economic growth mode and its sustainable development.He urged that plans should be made to forge a number of emerging strategic industries as the mainstay of China's economy as soon as possible, and that traditional industries should be upgraded with the latest technologies to enhance their efficiency and competitiveness. Chinese Premier Wen Jiabao (C) speaks as Chinese Vice President Xi Jinping(R) and Vice Premier Li Keqiang (L) listen in a seminar on the implementation of the Scientific Outlook on Development and the transformation of the mode of economic development in Beijing, capital of China, Feb. 4, 2010. The seminar, attended by the country's provincial and ministerial chiefs, opened on Wednesday at the Party School of the Communist Party of China(CPC) Central Committee in BeijingHe also called for stepped-up efforts in technological self-innovation, the creation and protection of intellectual properties.Reforms in China's education system must also be carried forward so as to promote quality education and to give the schools more say in their operation, the Premier said.Authorities must ensure free access to the nine-year compulsory education for all children, and to bridge the gap of imbalanced educational resources between urban and rural areas and between different regions and schools, Wen said.Vocational education should also be improved, he added.Noting that culture was an important factor in boosting the country's development and the revitalization of the nation, Wen said policies to support the development of cultural industries and innovations should be perfected.In addition, he stressed that boosting employment should be given top priority in China's social and economic development.Authorities should increase employment by maintaining stable and relatively fast economic growth, fueling the development of the service industry, labor and knowledge-intensive industries, and supporting the development of small and medium-sized enterprises and the non-public sectors, he said.They should also provide more training for people having difficulties in finding jobs, Wen said.The Premier also said the country's income distribution system should be perfected so that all 1.3 billion Chinese could enjoy the fruit of the country's reform and opening up drive.Authorities should make special efforts to raise the payment for people with modest or low incomes in both urban and rural areas in the country, especially farmers and migrant workers, he said, adding that tax tools should be better employed to adjust the income distribution.He also urged that the country's social security system should be perfected.A nationwide social security network should be set up, and medical reforms should be deepened in the country to provide the public with easy and equal access to medical services.The public should be fully motivated to contribute to the development of social undertakings, in order to improve the quality and efficiency of public services, Wen said.

HANGZHOU, Feb. 13 (Xinhua) -- Days before its 4,000 employees, mostly migrants, started off upon their annual trips home for the Chinese Lunar New Year, Tiansheng Group, a textile company in the eastern Zhejiang Province, promised pay rises hoping workers would all come back after the holiday."We are expecting a severe shortage of skilled workers this year," said Wei Guoliang, president of the company's trade union. "We'll be short of at least 1,000 workers in Spring."Lu Laofa (R), a 40-year-old migrant worker from southwest China's Guizhou Province, and his children make a free phone call with their relatives at the railway station of Hangzhou, capital of east China's Zhejiang Province, Jan. 31, 2010Located in Shaoxing County, Asia's biggest textile base, Tiansheng Group relies mostly on migrant workers from Anhui, Henan and Sichuan provinces for production.Fearing it might lose some of its best employees, the company's management offered an average 15-percent pay rise for all workers, plus higher meal allowances and better medical insurance starting on March 1.The offer was printed out and posted at the company's main entrance to catch the workers' attention."We don't know if it will work," said Wei. "But we do hope the workers will come back after the Spring Festival."Two farmer migrant workers who returned home for the Spring Festival take part in a lathe-hand technical training at Juye County, east China's Shandong Province, Feb. 5, 2010.While the Spring Festival falls Sunday, most migrants would stay home for about two weeks for the most important Chinese holiday.For years, migrant workers are the mainstay of labor forces in China's leading manufacturing bases in the Shanghai-centered Yangtze River Delta and the Guangzhou-centered Pearl River Delta.Yiwu City in Zhejiang Province, known for its small commodities including the world's biggest supply of toys and Christmas gifts, is also feeling the pinch of worker scarcity.After a recruitment tour to underdeveloped western provinces of Guizhou, Shaanxi and Yunnan last year, Huang Yunlong, head of the city's labor management bureau, said the situation would be tough for local employers this year.Migrant workers gesture on their chartered flight at the airport in Hangzhou, capital of east China's Zhejiang Province, Feb. 4, 2010In a recent survey in Lishui, a manufacturing town close to Yiwu, 4,000 of the 6,000 migrants who were heading home for the new year said they would stay in their hometowns for jobs or do farmwork after the holiday.Hoping to ease the labor shortage, Red Leaf Umbrella Co. encourages its employees to introduce new workers and offers a 600 yuan cash reward for each new recruit."The worker shortage is a result of the fast economic recovery, as well as the new policies by central and local governments to stimulate growth in the central and western regions," said Zhuo Yongliang, a researcher with Zhejiang Provincial Institute of Development and Reform.Amid the economic recovery, a Yiwu-based restaurant consumes 600 packs of wet tissues a day, as against 400 packs during the international financial crisis last year."The worker shortage, as well as the heavier workload for individual employees, have forced employers to offer better pays and compensation packages -- it's a good thing to this end," said Prof. Wu Jinliang with the Zhejiang Provincial Party School. "But it also eats way the competitive edge of thousands of small businesses that used to rely on cheap labor."Besides the worker scarcity, many entrepreneurs are also worrying about the skills and overall quality of their employees.Zhou Xiaoguang, president of a Yiwu-based decoration firm, remembers the dainty products he saw at an exposition in Europe. "Why can't we produce stuff like that? We can spend heavily to buy better equipment and hire better designers, but we don't have high-caliber workers at our production lines."Langsha Group, China's leading producer of socks and stockings, dropped a procurement plan last year for an Italian-made automatic packing machine that could spare the manual work of 30 workers and improve quality."No one is able to run the machine or fix it if it breaks down," said the group's president Weng Rongdi. "Our lack of training for the workers is a big problem.""Like all other Chinese manufacturing companies, we need high-caliber workers if we want to make further breakthroughs," he said.

BEIJING, Feb. 25 (Xinhua) -- Presidents of China and Zambia on Thursday pledged joint efforts to bringing bilateral relationship to a new high.The pledge came out of their hour-long summit talks in Beijing as China rolled out the red carpet for Rupiah Banda, who was on his first state visit to the country since becoming Zambian President in 2008.Banda was welcomed by Chinese President Hu Jintao at the Great Hall of the People in downtown Beijing.Chinese President Hu Jintao (R) holds a welcoming ceremony for visiting Zambian President Rupiah Banda in Beijing, China, Feb. 25, 2010.

China and Zambia forged diplomatic ties in October 1964.Banda highlighted "the sacrifices many young Chinese made in order to construct the first railway line connecting Tanzania and Zambia."The about-1,860-kilometer railway, one of the largest foreign-aid project undertaken by China, was financed and built by China in 1970s. More than 60 Chinese died in constructing the railway.
