WASHINGTON - China warned the United States on Thursday against "groundless smear attacks" against Chinese products and said it was working responsibly to address concerns over a spate of recent food safety scares. "The Chinese Government has not turned a blind eye or tried to cover up. We have taken this matter very seriously, acted responsibly and immediately adopted forceful measures," said a statement by China's embassy in Washington. "Blowing up, complicating or politicizing a problem are irresponsible actions and do not help in its solution," the Chinese mission said in a rare policy pronouncement. "It is even more unacceptable for some to launch groundless smear attacks on China at the excuse of food and drug safety problems," it said. Echoing the Beijing government's complaints about US media reports, the embassy said food safety concerns were not unique to China, 99.2 percent of whose food exports to the United States in 2006 met quality standards. Problematic US imports from China -- including toxic ingredients mixed into pet food and recalls of toy trains and toothpaste -- were isolated cases and "hardly avoidable" amid huge and rapidly growing bilateral trade, the statement said. "It is unfair and irresponsible for the US media to single China out, play up China's food safety problems and mislead the US consumers," it added. Appealing for strengthened cooperation between Chinese and US food inspection authorities, the statement urged Americans to "respect science and treat China's food and drug exports fairly."

President Hu Jintao will "elaborate on China's position and propositions on climate change" at the upcoming summit of industrialized nations which features a session on global warming. Assistant Foreign Minister Cui Tiankai told a news briefing yesterday: "China's population is one-fifth of the global population, which means one out of five of the world's people affected by climate change will be in China. "That is why the Chinese government takes this issue very seriously... We need to base our development on energy that is secure and sustainable." Hu will attend an expanded summit of the Group of Eight (G8) in Germany from tomorrow to Friday. The meeting at the Baltic Sea resort of Heiligendamm will bring together leaders of the United States, Britain, Canada, Germany, France, Italy, Russia, and Japan. German Chancellor Angela Merkel is pushing for countries to commit to concrete reductions in the emissions of greenhouse gases believed to cause global warming, and for a 2 C limit on further increases in average temperature. Efforts to stop uranium enrichment by Iran, aid to Africa, currency exchange rates and global growth are also on the agenda. Apart from China, the other developing countries attending the dialogue are India, Brazil, South Africa and Mexico. It will be the fourth time Hu is attending the G8 outreach session since 2003. The earlier three were in France, Britain and Russia. Coinciding with Hu's visit, the Chinese government yesterday released its position paper for the G8 meetings, outlining Beijing's policy on climate change, energy, IPR protection, investment liberalization and African development. Cui reiterated China's long-time and traditional friendship with African countries. "China and African countries have had a very friendly, brotherly partnership since the establishment of New China, since the 1950s, and that has continued up to now," he said. "It can be said that this has been widely praised around the globe," he added. "In this world, there will always be people willing to criticise others. If they want to say something, then that's their business. Whether or not it's true, is another matter." He said China also wants the United Nations to be more involved in preventing conflict. "China maintains that the United Nations has a bigger role to play in conflict prevention and settlement and post-conflict reconstruction in Africa," the paper said. UN Secretary-General Ban Ki-moon on Friday praised China's "helpful" role in Sudan. "The Chinese government has been exerting its utmost efforts (on Darfur), as I understand, and appreciate," he said. After Germany, Hu begins a three-day state visit to Sweden, the first by a Chinese head of state in 57 years since the two countries established diplomatic ties. Agencies contributed to the story

Five needy college students in Central China's Hubei Province are being denied further financial aid because they never expressed their thanks to the benefactors who helped them pay their bills last year.The beneficiaries, in Xiangfan, were said to have been indifferent to their sponsors because they never called, wrote or even thanked them for the financial support they had received, local media reported.Sina.com asked more than 200,000 people what they thought of the subject Wednesday, and more than 83 percent of respondents said they thought it was right to cut off the financial aid to the students. Roughly 9 percent said they did not agree and the rest said no comment.Under the aid program, organized by the Xiangfan Federation of Trade Unions and Xiangfan Women Entrepreneurs Association last August, 19 businesswomen offered financial support to 22 needy college students.Each benefactor promised to give 1,000-3,000 yuan (0-400) every year to each student for the next four years.The federation sent letters to the students and their families before they enrolled in college, suggesting they occasionally write letters to their sponsors to brief them on their studies. However, two-thirds of the students failed to do so.Some of the businesswomen refused to sponsor the students this year because they said "some students were cold-blooded"."The situation is embarrassing. Most of the students have a strong sense of pride. They lack a proper and optimistic attitude toward others and society. Maybe, some of them took the sponsorships for granted because they thought they were good students and deserved the support. That's why they didn't think to say 'thank you'."Zhou Ping, deputy chairperson of Xiangfan Federation of Trade Unions"We cannot refrain from eating for fear of choking on the food. It will not help these disadvantaged students to cut off their support. If they have faults, they should get help correcting them. Financial aid and other kinds of charity should focus on helping escape their difficulties, both spiritually and materially. "Zhou Xiaozheng, a professor of Renmin University of China in Beijing"Financial resources are limited, and many students are waiting to share them, so there is no room for ungrateful citizens who might have no will to repay society. There are many examples of impoverished students who spend their financial aid on luxury products, which discourages others from offering them donations."Li Chengpeng, a media commentator"I support cutting off the aid. The benefactors do not feel the value of their good deed and the beneficiaries do not feel grateful for the help. If the relationship is to be maintained, it might be harmful to both sides."Zhu Jun, a lawyer

Chinese photographers said the South China tiger on digital pictures, released by forestry authorities and widely discussed on the Internet, is a fake.A preparatory digital picture appraisal center under the China Photographers Society, released the results on Sunday after a team of photographic experts assessed the 40 digital pictures provided by NetEase, a Chinese Internet company.The State Forestry Administration, however, on Tuesday refused to comment on the authenticity of these pictures, saying its responsibility is to protect the wildlife.Cao Qingyao, SFA spokesman, did cite previous investigation resultsat a press conference in Beijing, saying the investigators found some traces of South China tigers in Shaanxi, and said a new investigation in the area is under way, and the results will be announced as soon as possible. The center said technological analysis from last Tuesday through Sunday showed the South China tiger on the 40 pictures was not real and could not serve as evidence for the existence of the wild animal.The pictures must have been taken by people with photographic experience or under guidance and could not be done independently by a person without any photographic experience, claimed experts.The digital picture, purporting to be a wild South China tiger crouching in the midst of green bushes, was released by the Forestry Department of northwest China's Shaanxi Province at a news conference on October12.Zhou Zhenglong, 52, a farmer and former hunter in Chengguan Township of Shaanxi's Zhenping County, photographed the tiger with a digital camera and on film on the afternoon of October 3, a department spokesman said.The Shaanxi forestry department said it had confirmed the 40 digital pictures and 31 film photographs were genuine.But the pictures released were not the original ones and they underwent modifications, such as time and signal, according to experts.Bao Kun, an expert who participated in the appraisal by the center, told Xinhua they announced the results out of "a citizen's sense of social responsibility."A detailed report concerning the appraisal would be announced in about a week, Bao added.In response to the appraisal results, the Shaanxi provincial forestry department said in a written statement to media that they had already "showed their attitude toward the South China tiger issue and would continue to pay attention to the matter.""We thank netizens and media for your care of the South China tiger and of the wildlife protection cause," the statement said, offering no direct comment on the appraisal results."In a statement on November 23 the department said: "We firmly believe this basic fact: That wild South China tigers exist in Zhenping county of Shaanxi Province."The South China tiger, from which other sub-species such as the Siberian tiger evolved, is listed as one of the world's ten most endangered animals.It is the only tiger subspecies native to China's central and southern areas. In the early 1950s, its population was 4,000 across the country. Since 1964, no sightings of wild tigers have been reported in Shaanxi.Its former habitats were in Guangdong Province, Guangxi Zhuang Autonomous Region and the central provinces of Hunan and Jiangxi.

BEIJING - State Forestry Administration investigators found more than 100 suspected footprints of a South China tiger on Friday in Shaanxi Province, where photos of the big cat taken by a farmer have caused a national controversy over their authenticity.A South China tiger [File photo] The Beijing Morning Post reported on Monday that Zhang Bin, a local forestry official who accompanied the investigators, said the team also found a skeleton suspected to belong to a young tiger."It's like the skeleton of a cat," said Zhang, adding the bones had been sent to Beijing for DNA testing. "But experts said with a length of 50 centimeters, a cat would have grown tooth bones. This skeleton hasn't (teeth), it's like a cub feline.""The experts said there is a great probability that it belongs to a South China tiger cub."He said the footprints found in Zhenping County ranged from 12 to 16 cm, with toes. "To my experience in investigating the wild, they are tiger footprints. They belong to more than one tiger."Zhang said the experts had also developed rubbings of the footprints for further analysis.In October, a farmer in Zhenping County, in the northern Shaanxi Province, claimed he snapped photos of a tiger in the forest near his home. The provincial forestry bureau later cited experts as verifying it was a South China tiger. The subspecies was believed to have been extinct in the wild for more than three decades.However, many scientists and Internet users have denounced the pictures as fake. In November, one netizen posted an on-line picture of a tiger from a new year calendar and claimed the two tigers were identical.Despite this, the provincial forestry department insisted the tiger in the photo existed in Zhenping County. The Beijing-based China Photographers Society, however, confirmed the images were not real.Last month, the State Forestry Administration dispatched an expert panel to Zhenping to carry out a field investigation. It hoped to find concrete evidence on whether the tiger existed.The photo taken by Zhou Zhenglong, a farmer in Zhenping County of Northwest China's Shaanxi Province. Zhou claimed he snapped photos of a South China tiger in the forest near his home.
