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 7 (Xinhua) -- President Hu Jintao on Sunday urged the Chinese women to contribute more to the country's development and modernization on the eve of the 100th anniversary of the International Women's Day.Addressing a gathering marking at  the event the Great Hall of the People, Hu said Party committees and governments at all levels should resolutely carry out the basic state policy of equality between men and women, eliminate discrimination against women, and crack down on violations of women's rights in light with law.Hu stressed that women's equal rights of political participation, equal participation in economic and social development, and equal access to benefits brought by economic development must be protected. Chinese President Hu Jintao, who is also General Secretary of the Central Committee of the Communist Party of China (CPC) and Chairman of the Central Military Commission, shakes hands with female representatives before a meeting which marks the 100th anniversary of the International Women's Day at the Great Hall of the People in Beijing, China, March 7, 2010Noting that the Chinese women have made great contributions in process of building the New China and realizing the Chinese nation's rejuvenation, Hu also called on the women to play a bigger role in carrying forward the country's modernization drive.Hu expressed his festival greetings to the women and extended thanks to international organizations and friends for their support to the development of the Chinese women's undertakings.Other Chinese leaders including top legislator Wu Bangguo and Premier Wen Jiabao also attended the gathering.

TAIPEI, Feb. 15 (Xinhua) -- Taiwan leader Ma Ying-jeou said Monday that the Economic Cooperation Framework Agreement (ECFA) with the mainland is aimed to help Taiwanese people to do business and boost the island's competitiveness.Ma made the remarks in Taoyuan, a northwestern county of the island, at a gathering to mark the Chinese Spring Festival, or Lunar New Year.The ECFA is a wide-ranging economic pact for further normalizing trade and investment ties across the Taiwan Strait, which Ma hopes to sign with the mainland this year to help fuel Taiwan's economic revival.Tariff reduction would promote the sales of goods from Taiwan to the mainland, which will benefit both the Taiwanese businesses and the foreign-funded businesses in Taiwan, Ma said.This will help Taiwan to introduce more foreign investment and grant the island an opportunity to become a hub of economy and trade in the Asia-Pacific region, he said.As the mainland is Taiwan's biggest trade partner, the pact will certainly do more good than harm, Ma said.Ma also attended an ancestor worship ceremony in Majiazhuang, Miaoli County on Monday and said that the ancestors of him and local residents moved from Fufengtang, northwest China's Shaanxi Province, to the island some 2,000 years ago.He also spoke optimistically of the economy situation and expected an economic growth of 4 percent in Taiwan this year.

BEIJING, Feb. 5 (Xinhua) -- The State Council of China Friday issued an urgent notice urging relevant departments and local authorities to settle pay disputes involving migrant workers as millions of them are heading home for lunar new year reunion.The notice asked local governments and relevant departments to prioritize in their work the settlement of migrant workers' back pay dispute with their employers.It underlined the construction industry where back pay disputes often happen.It also ordered local governments to improve the emergency management system to respond to possible mass incidents caused by pay disputes.Two migrant workers were stabbed to death by their employer over a pay dispute Wednesday in central China's Henan Province.The two men asked for wages on behalf of 17 fellow workers and got into a fight with their labor contractor after being told that their monthly payment had been docked by over 100 yuan (about 14.6 U.S. dollars), and then were stabbed in the neck with a fruit knife by the contractor.In China, millions of migrant workers from the countryside make their living in booming cities. Back pay to migrant workers has affected the income of the rural population for a long time and is considered a "chronic illness" undermining social stability.

SHANGHAI, March 23 (Xinhua) -- There has been no timetable for the construction of a maglev line project between Hangzhou and Shanghai, a spokesman of the Shanghai municipal government said Monday.The project is still undergoing feasibility studies, the official said when responding to media reports last week which said the construction is expected to start this year.The proposal of the ultra-high-speed maglev line, with an estimated cost of 22 billion yuan (3.22 billion U.S. dollars), was approved by the National Development and Reform Commission in 2006.When completed, the line is expected to cut the travel time between Shanghai and Hangzhou, capital of the neighboring Zhejiang Province, to half an hour from the current 2.5 hours.
