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.

China has paid its dues to the UN in time, one of China's representatives to the world body has said."This year, assessed contributions (UN membership dues) and peacekeeping assessments both will go up significantly for China, with the total being 0 million, a 42 percent increase against last year," a member of China's delegation to the Fifth Committee of the 62nd UN General Assembly, Yu Hong, said.Speaking at a conference on "Improving the Financial Situation" of the UN in New York last week, he said China has provided equipment worth more than million to its peacekeeping troops in Sudan and Liberia, too.The country will pay the bulk of its outstanding peacekeeping dues before the end of the year, Yu said."China has a very good reputation in fulfilling its financial promises to the UN," Wu Miaofa, a UN expert with the China Institute for International Studies, said. "China has become an active participant and constructor of the organization."The increase in China's financial contribution and its fulfilment of the promises show that it's willing to shoulder more international responsibility, he said.The UN's financial condition has deteriorated this year because of the rise in unpaid contributions."A sound financial condition is most important for the UN to perform its functions as the most important world body," Wu said, urging all member states to honor their financial obligations in time.

BEIJING -- China has ordered its police to behave well and improve their services to the public as the country marks the one-year countdown to the 2008 Beijing Olympic Games. The Ministry of Public Security has launched a one-year inspection campaign in Beijing and other cities hosting Olympic events as well as major tourist cities to ensure a polite, standard and efficient police services to citizens and foreign visitors. The inspection mainly deals with police who take a bad attitude towards the public and do not wear standard uniforms and insignia. An inspection team will oversee police service departments such as community police stations, traffic police brigades, patrolling cops, border entrance and exit offices, reception rooms for foreigners, border checkpoints, visa application centers and police alarm "110" phones. Police who smoke, chew food, chat or use chilly words in front of the public will be immediately punished by inspectors on the spot, says the ministry, adding the inspection team will find out whether the police can take proper, immediate and effective actions when the public, especially foreigners, ask for help. The campaign, which is a part of the overall Olympic security deployment, is aimed at maintaining a sound order for the upcoming congress of the Communist Party of China and the Olympic Games next August, and setting a good image of the Chinese police, according to the ministry.

Another two closed-end stock funds have received official approval from China's securities regulator, Xinhua learned from a company source here on Friday.     The China Nature Asset Management Co. Ltd's Tianzhi Fund and the Dongwu Fund run by Soochow Asset Management Co., Ltd received regulatory approval from the State Securities Regulatory Commission Friday.     The Tianzhi stock fund will open through China Communication Bank, China Construction Bank, the Agricultural Bank of China, the Industrial Bank Co., Ltd, Shanghai Pudong Development Bank, CITIC Bank, Minsheng Banking Corp., Ltd, and with big brokers.     The Dongwu fund is to be issued by the Industrial and Commercial Bank of China, the Agricultural Bank of China, China Construction Bank, the Postal Savings Bank, Huaxia Bank and qualified individual brokers.     Both companies declined to say how much they expected to reap from the listing.     Four stock funds launched by Bank of China Investment Management Co., Ltd. and AXA SPDB Investment Managers, CCB Principal Asset Management Co. and China Southern Fund Management Co., respectively, received official approval in the first half of February.     Of the four, CCB Principal Asset Management's Jianxin Fund and the Nanfangshengyuan Fund run by China Southern Fund Management Co. made their debut on Feb. 18.     Market analysts said the launch of these funds was expected to bring a new round of fresh capital into the sliding stock market.     China's securities watchdog suspended the launch of new funds late last year in reaction to the surging domestic stock market. The Shanghai Composite Index nearly doubled last year.

The second batch of quotas for qualified foreign institutional investors (QFII), a scheme for foreign players to invest in the A-share market, is likely to be about billion, an industry insider, who declined to be named, told China Daily on Friday. The source said that the second batch of QFII quotas was being discussed, and pending approval by the Chinese government, was likely to be about billion, not exceeding that of the last batch, which was billion. Hu Xiaolian, Deputy Governor of the central bank and Administrator of the State Administration of Foreign Exchange (SAFE), said earlier that related rules on the QFII scheme were being amended and the total QFII quota would certainly see an increase in 2007. However, she declined to give a specific sum. China has so far approved 52 overseas institutions as QFIIs to invest in the A-share market, of which 49 have got a combined investment quota of .995 billion from SAFE, near the upper limit of billion as stipulated previously. Industry insiders said the demand for QFII quotas was strong at present and more should be granted. "Despite the excessive liquidity in the A share market, the Chinese government should grant more quotas to QFIIs. Otherwise, they will find other ways, making it more difficult to supervise," She Minhua, an analyst with CITIC China Securities said. Meanwhile, the booming Chinese stock market is attracting more foreign financial firms to set up joint ventures in the investment sector. The Financial Times on Thursday reported that Nikko Asset Management, a QFII approved in 2003, has become the first Japanese fund firm to acquire a 20 per cent stake in a local firm, the Shenzhen-based Rongtong Fund Management Company. Nikko AM bought the stake from Shaanxi International Trust & Investment (SITI), for 3.8 yuan per share, valued at 475 million yuan, according to a statement by the Shenzhen-listed SITI.

The Chinese government is working on specific regulations for collecting royalties from television, radio stations for using music works, a senior official said in Beijing over the week.However, it has not been decided when the regulations will be publicized, Liu Binjie, director of the General Administration of Press and Publication (GAPP) and the National Copyright Administration (NCA), was quoted as saying.The Chinese government's efforts in combating piracy and protecting intellectual property rights (IPR) have resulted in more shops and restaurants signing up to pay royalties on the ubiquitous background music that had long been used for free.Background music played at department stores or hotels -- also called "muzak"-- received legal protection in China in 2001 under revisions to the Copyright Law. The law states that both live and mechanical performances enjoy the same rights. Up to now, most big hotels, department stores and supermarkets in Beijing and Shanghai have paid fees to the Music Copyright Society of China (MCSC) for using the songs under their administration, according to sources.And Karaoke bars in China's main cities were made to pay 12 yuan (US.50) a day in royalties to music artists for each room, according to a regulation set by China's National Copyright Administration late last year.However, most television and radio stations in China are still using music works without paying any royalties.The Music Copyright Society of China is now negotiating with television and radio stations on copyright fee payments, China Press and Publishing Journal reported.The Music Copyright Society of China is the country's only officially recognized organization for music copyright administration.The association has now administered copyrights for over 14 million music works by 4,000 members.Public venues including hotels, restaurants and department stores are charged with different standards by the society. The usual fee is 2.54 yuan (US.9) per square meter per year for a department store of 10,000 to 20,000 square meters to use the music, the society said.

In the hall of the so-called "Tibetan government in exile" in Dharamsala, India, there is a large map of the supposed "greater Tibet area".The area covers the Tibet Autonomous Region and Qinghai Province, one-fifth of the Xinjiang Uygur Autonomous Region, one-third of Gansu Province, two-thirds of Sichuan Province and one-fourth of Yunnan Province, spanning about 2.4 million sq km and nearly a quarter of China's territory.Holidaymakers take photos with digital cameras near the Potala Palace in Lhasa, the Tibet Autonomous Region. [China Daily] The ** Lama has advocated a "high degree of autonomy" for Tibet in such a geographic scope and made it a preliminary condition for any negotiation with the central government. But such an idea is totally absurd for three major reasons.First, the distribution and the layout of the Tibetan population and the administrative divisions were formed during the long process of historical development; there is no historical basis for an administrative division such as "greater Tibet area".Archaeological excavation and documentation show the Qinghai-Tibet Plateau area has long been inhabited and has a diversified culture.In the Sui Dynasty (AD 581-618) and the Tang Dynasty (AD 618-907), the Qinghai-Tibet Plateau was an area cohabited by different ethnic groups.The regime of Tubo Kingdom (AD 629-840) coexisted with others such as the Tang Dynasty, Uighur and Nanzhao, in a territory cohabited by various ethnic groups and tribes.The headquarters and the main area of jurisdiction of the Tubo Kingdom basically constitutes the Tibet Autonomous Region today while other dependent territory is the region inhabited or cohabited by various ethnic groups.During the Yuan Dynasty (1271-1368), three chief military commands (three Pacification Commissioner's Offices) were established in areas with Tibetan traditions, namely U-Tsang Ngari, Amdo and Lhams, the divisions of which were carried out in the Ming Dynasty (1368-1644) and laid the base for the administrative division of today's Tibet and other Tibetan administrative divisions.The Qing Dynasty (1644-1911) further defined the boundary between Tibet, Sichuan and Yunnan. In 1731 the Qing government divided the border of the areas under the jurisdiction of the grand minister resident of Tibet and the grand minister superintendent of Xining. The administrative division of Tibet has not changed much since.Second, the so-called administrative region of "greater Tibet area" is a historical product of the invasion by imperial powers. From 1913 to 1914, the British-instigated Simla Conference was held, which brought up the concept of the so-called "greater Tibet area" - that the territory of Tibet covers part of Xinjiang to the south of Kunlun Mountains and the Anding Tower, the whole of Qinghai Province, the western areas of Gansu and Sichuan provinces, and Dajianlu and Adunzi in the northwest of Yunnan Province.When this was rejected by the representative of the Chinese government, Britain proposed again to divide the Tibetan-inhabited areas of China into inner Tibet and outer Tibet. The former referred to the small parts in Yunnan, Qinghai and Xikang, where the central government would enjoy dominion; outer Tibet included U-Tsang, Ngari and most of Xikang, which was to be governed by the Tibetans themselves.This shows that from the very beginning, the so-called "greater Tibet area" has been a separatist plot. Even the weak Northern Warlords government of China saw through the imperialist trick to split China and refused to sign the convention. How will Chinese people today allow the government to accept such an imposition?Third, there is no possibility for realization of an administrative region such as "greater Tibet area". Since the New China was founded, the central government, on the one side, has followed historical divisions, and on the other, according to the requirements of the Constitution and the Law of Regional Autonomy for Ethnic Minorities, considered the various factors for the economic, political and cultural development of the Tibetan-inhabited areas to establish eight Tibetan autonomous prefectures, one Mongolian and Tibetan autonomous prefecture, one Tibetan and Qiang autonomous prefecture, two Tibetan autonomous counties and the Tibet Autonomous Region through full discussion of people's representatives from various regions.In the past half-century, as the administrative divisions were well set, the system of regional autonomy for ethnic minorities has been gradually improved and guaranteed the equal rights of Tibetans and other ethnic groups living in the region.It has promoted national unity and social economic development and given full support by the Tibetan people and other ethnic groups.The ** Lama, however, has been insisting on the establishment of a political entity in Tibetan-inhabited areas to build an "alliance" relationship with China, requiring all other ethnic groups to move out of the so-called "greater Tibet area" and millions of people to give up their ancestral homes.This is not only an attempt to change the current relation between the central and the local government, but also a move to implement ethnic discrimination and ethnic cleansing. We must learn from the slaughters and bloodshed caused by ethnic conflicts and disputes the world over.Then why does the ** Lama insist on this groundless and impossible concept of "greater Tibet area"? There are at least two reasons. One is that many of the Tibetan people exiled with the ** Lama in 1959 are from Tibetan areas outside the Tibet Autonomous Region. The ** Lama needs to set a common illusion of "a united, independent and free Tibet" to buy these people's support. The other reason is that the claim was designed by their foreign bosses and they, as their flunkies, dare not disobey it.The ** Lama and his followers in his "government in exile" have often expressed their recognition of the Simla Conference. Therefore, the so-called "greater Tibet area" in essence is "semi-independent" or in "disguised independence", which aims to serve the open and complete "Tibet Independence" and disunite a quarter of China's territory in future.But the ** Lama and his alike do not really understand that the political claims they make against historical development and reality to please their foreign bosses, no matter under what splendid banners, are only "medieval fantasies" that go against the time and the interests of Tibetan people as well as people of all ethnic groups in China. The Chinese government will not be fooled!

CHENGDU - About 3.8 trillion cubic meters of natural gas deposits have been discovered in southwest China's Sichuan Basin, with verified exploitable reserves topping 600 billion cubic meters. The reserves were discovered in Dazhou, a gas-rich city in Sichuan Province. By 2010, the newly found deposits will raise the city's gas output to 24 billion cubic meters and sulphur to more than 4.3 million tons, according to a Dazhou official at the on-going Western China International Economy-Trade Fair on Saturday. China National Petroleum Corporation (CNPC), the country's biggest oil and gas producer, and Sinopec Corporation, China's largest refiner, plan to build five purification plants in Dazhou and are expected to purify a total of 74 million cubic meters of natural gas a day by 2010. Dazhou City, located in eastern Sichuan, covers an area of 16,600 square kilometers with a population of 6.46 million.
