WASHINGTON -- The special US envoy on Sudan affairs said Wednesday that important progress has been made toward peace talks on Darfur and China plays a "constructive" role in facilitating such progress."I am very happy with the role the Chinese are playing," Andrew Natsios said in a speech at the Center for Strategic and International Studies, a Washington-based think tank."It is a constructive role," Natsios said. "I think the Chinese are like a locomotive that is speeding up."With mediation by China, he said, the Sudanese government has accepted a UN Security Council resolution adopted in July to authorize a hybrid UN-African Union peacekeeping force for the Darfur region.He said the major obstacles to the peace talks now come from the rebel groups rather than the Sudanese government.In a related development, China's Special Representative on African Affairs Liu Guijin said in Beijing on Tuesday that China will send a military liaison officer to Sudan's Darfur.Liu, who has just wrapped up a seven-day visit to the United States and the United Nations, said China has informed the UN of its decision.China also pledged to send a 315-member multi-functional engineering unit to Darfur in early October, which would be the first batch of UN-AU peacekeepers in place, and China will stick to its commitment, Liu said.Liu reiterated China's constructive and unique role in finding a solution to the Darfur issue, saying China has provided much aid and help with regard to the reconstruction and development of Darfur."The US and UN both hold positive views on China's role in resolving the Darfur issue, and hope China will play a bigger role in this regard," said Liu.

WASHINGTON - Post-menopausal Chinese women who eat a Western-style diet heavy in meat and sweets face a higher risk of breast cancer than their counterparts who stick to a typical Chinese diet loaded with vegetables and soy, a study found. The researchers, writing on Tuesday in the journal Cancer Epidemiology, Biomarkers & Prevention, tracked about 3,000 women in Shanghai, about half of whom were diagnosed with breast cancer. Post-menopausal women who ate a Western-style diet -- beef, pork, shrimp, chicken, candy, desserts and dairy products -- were 60 percent more likely to develop breast cancer than those eating a diet based on vegetables and soy, the study found. The study found the increased risk most acute for cancer involving so-called estrogen-receptor positive tumors. The post-menopausal women with the Western-style diet experienced a 90 percent increased risk for this type of breast cancer. One of the researchers, Marilyn Tseng of the Fox Chase Cancer Center in Philadelphia, said the study detected a much smaller increased breast cancer risk among younger women on a Western-style diet which was not statistically significant. Tseng noted that breast cancer rates among Asian women traditionally have been low but have been rising in recent years. Some experts have suspected that the adoption of a more Western diet may be at least partly to blame. "The increase in risk did appear to be due to the increase in red-meat intake," Tseng said in a telephone interview. "But we didn't do specific analyses to see if it could have been due to other parts of a western diet, like the high intake of desserts or high intake of dairy." The findings also suggested such a diet may increase breast cancer likelihood by increasing obesity, the researchers said. "We are the first to find evidence for an increased risk of breast cancer for a Western-style dietary pattern in an Asian population," the researchers wrote. They detected two dietary patterns in the women, who were diagnosed with their cancer from 1996 to 1998 and were subsequently interviewed about what they ate. One was a "vegetable-soy" pattern based on tofu, cauliflower, beans, bean sprouts and green leafy vegetables, with not much meat. The other was a "meat-sweet" pattern among women gravitating away from typical Chinese fare in favor of more Western foods. "Most studies have tended to look at single dietary factors. And what was unique about this study is that we tried to describe patterns of intake -- foods that go together, that seem to occur together in the diet," Tseng said.

TAIYUAN -- Fifteen miners have been confirmed dead following Saturday's gas explosion in a coal mine in Linfen City, north China's Shanxi Province, rescuers said on Sunday. Rescue operation is still going on. The gas blast occurred around 1:50 p.m. on Saturday at Pudeng Coal Mine in Kecheng Township of Puxian County. About 30 miners were trapped underground, according to preliminary estimates. "The exact number of miners trapped underground is yet to be affirmed," said a spokesman for Shanxi Provincial Bureau of Coal Mine Safety Supervision. The cause of the gas explosion is being investigated. Pudeng Coal Mine, which is in operation with permits, produces 150,000 tons of coal a year. Zhao Tiechui, director of the State Administration for Coal Mine Safety Supervision, together with local officials have rushed to the accident site to direct rescue efforts.

Beijing's top official on cross-Straits affairs Monday condemned a referendum pushed by Taiwan leader Chen Shui-bian as a move that is threatening to drag ties into a "high-risk period".Chen Yunlin, minister of the Taiwan Affairs Office of the State Council, called the referendum to join the United Nations under the name of Taiwan as a "scheme" aimed at de jure independence for the island.The Taiwan authorities led by Chen Shui-bian are "attempting to change the cross-Straits status quo that both the mainland and Taiwan belong to one China " Chen Yunlin said in a signed article published Monday in the latest issue of Qiushi (Seeking Truth) journal, a publication of the Central Committee of the Communist Party of China.The article came amid mounting concerns from across the Straits and international community over the proposed referendum, which is expected to strain cross-Straits relations and threaten regional stability.In an interview with a German newspaper published Monday, Chen Shui-bian insisted the referendum for Taiwan's admission to the UN will be slated for March as scheduled, along with the island's "presidential" elections.The Taiwan leader was quoted as saying he has no rights to "veto the referendum".Raymond Burghardt, chairman of the American Institute in Taiwan, rapped Chen Shui-bian in a meeting in Taipei last week, saying the United States is greatly concerned about the referendum and hopes it will be scrapped.He said his remarks represented views from the "highest level in Washington".Once Chen Shui-bian's plot materializes, "it will bring serious consequences cross-Straits relations and peace", Chen Yunlin warned in the article.The minister said the fight against pro-independence forces is becoming more and more intense as their secessionist activities are being intensified.He stressed that "China's sovereignty and territorial integrity brook no division, and any matter in this regard must be decided by the entire Chinese people including our Taiwan compatriots"."The 1.3 billion Chinese people will never swallow the bitter fruit of 'Taiwan independence'," Chen Yunlin said.He reiterated that Beijing will stay on high alert of any desperate moves of the secessionist forces of Taiwan.In the event that "Taiwan independence" secessionist forces should act under any name or by any means to cause Taiwan's secession from China, or that major incidents entailing Taiwan's secession from China should occur, we shall resort to necessary measures without hesitation to safeguard national sovereignty and territorial integrity, our core national interests," he said.
