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.

National guidelines on economically affordable housing were released on Friday night along with new State measures on housing for low-income families, which come into effect on Saturday.Economically affordable houses ought to be around 60 sq m per unit, said the guidelines jointly released by the Ministry of Construction, the National Development and Reform Commission, and five other ministries.It said eligible purchasers will "have limited property rights", and that the apartments can only be directly sold after five years.Moreover, the document limited fundraising for cooperative housing units to independent mining corporations on the outskirts of cities and enterprises with a significant number of employees with housing problems, while stressing that they must do so with their own properties.Eligible applicants of the Measure on Low-rent Housing Security, meanwhile, are no longer limited to city households with the lowest income, but will also include all lower-income urban families with housing issues.Government subsidies, the usual means of securing housing for these social groups, are to be gathered from rental fees on low-rent housing, credit risk reserves, housing provident funds, social donations and security funds. Local governments must also spend 10 per-cent of the local land-use fees on developing low-rent housing, said the measure, released by nine ministries on Monday.Because situations vary across the 656 cities that had adopted the mechanism as of October, the measure allows special funds to be allocated to central and western regions that find it financially difficult to support the construction of low-rent homes.Additionally, the construction area of these apartments, limited to 50 sq m per unit, should be granted preferential status on a stand-alone basis in land supply schemes and annual land-use applications.Months earlier, the central government urged local governments to reserve at least 70 percent of the land designated for residential construction for units under 90 sq m. But since the housing security system is expected to cover all low-income Chinese families by 2010, implementation of the new measure and relevant policies has a long way to go.Figures from the Ministry of Construction show that nearly 10 million households still live in a housing space, per capita, of less than 10 sq m. Up to the end of 2006, only 268,000 families, or 6.7 percent of all households living on a minimum allowance, and 2.7 percent of all low-income households in China, had benefited from low-rent housing policies.Despite a record 7.04 billion yuan (.52 million) of central government investment in low-income housing so far this year, 50 billion yuan is needed every year for the next five years to continue to broaden coverage, the People's Daily reported.To address the housing problems of urban low-income families, for example, Shanghai is to pour in a total of 2 billion yuan in providing 500,000 sq m of low-rent apartments by the end of this year, Shanghai's Jiefang Daily reported on Friday.The money will come from the 8.3 billion yuan coffers of the Shanghai public housing reserve fund.Cong Chen, a staffer at the Department of Policy and Regulation of Shanghai Provident Fund Management Center, confirmed the information.The project, launched last month, has already secured 150,000 sq m of land in Jiading, Baoshan and several other districts in Shanghai, 70 percent of which are completed flats.These flats are said to be lo-cated in areas with comparatively mature transportation and living facilities, such as metro stations and bus stops, for the convenience of low-income tenants, the Jiefang Daily said.

Major travel agencies had cut prices of domestic group tours by an average 30 percent as of yesterday, as the weeklong National Day holiday approaches its conclusion.The discount trips cover some top attractions, including Jiuzhaigou in Sichuan Province, Lijiang in Yunnan Province, Zhangjiajie in Hunan Province and some spots in the Xinjiang Uygur Autonomous Region.Costs for outbound tours have also been cut.The prices of tours to Japan and the Republic of Korea have fallen by as much as 1,000 yuan (3), according to www.ctrip.com, a travel service company.The country's tourism market saw a peak yesterday, the National Holiday Office said in a statement.More than 90 percent of the hotel rooms in most tourist destinations were booked, the statement said.The office said the 119 scenic spots in its nationwide monitoring system had received 3.28 million tourists on Wednesday and 3.07 million yesterday.Beijing's mass transit railway system carried 3.74 million people during the first two days of the weeklong holiday, according to municipal metro authorities.The number was almost double the amount on a normal day.An official with the Beijing environmental sanitation group said tourists had left about a third of the garbage at Tian'anmen Square each day that they did last year.Sanitation workers cleared 26.6 tons of garbage from the square in the first two days of the holiday, compared with 80 tons last year.

The highly anticipated Beijing-Shanghai high-speed railway will begin construction next month, a Ministry of Railways official said.The ministry source, who did not want to be named, confirmed in a phone interview yesterday that preparations are now being made for a ceremony to commence construction of the system.Based on that timeframe, the railway will be completed by 2013. Trains running on the 1,318 km railway will then be able to travel at speeds of up to 350 kph and will cut travel time between the two cities from the current 10 hours to less than five.The project involves one of the largest amounts of investment on railways. Industry sources say it will cost more than 200 billion yuan ( billion), more than the 180 billion yuan needed for the Three Gorges Project.Officials say the project will also employ a set of locally developed high-speed railway technology for the first time.The country is said to have already mastered the technologies needed to lay high-speed rail tracks and trains.The first homegrown train able to reach 300 kph rolled off the production line over the weekend, marking China's entry into "an elite club that includes Japan, France and Germany to become the fourth country capable of making such trains", Wang Yongping, Ministry of Railways spokesman said.Officials added that the railway still relies on foreign companies, such as the Germany-based Siemens, to build its signal network and other systems.China has been upgrading the scale and speed of its railway network in the past decade, and the 11th Five Year Plan period (2006-10) is regarded as a critical period for building high-speed railways that can travel at speeds of 200 kph as part of an extensive transport network.At least eight express passenger railways were being constructed as of last year.Xinhua contributed to the story

BEIJING - China's currency, the yuan, hit a new high against the US dollar on Thursday, following an overnight key interest rate cut in the United States.The yuan, also known as the renminbi, went up 145 basis points from the previous day to a central parity rate of 7.1853 yuan to one dollar, breaking the 7.19 mark.The Federal Reserve on Wednesday cut US interest rates by a bold half-percentage point as part of its efforts to shore up economic growth.The move came just eight days after the US central bank slashed rates by three quarters of a percentage point, leading the dollar to weaken against other major world currencies.The Chinese currency had appreciated against the greenback by about 12 percent since a new currency regime was imposed in July 2005 to revalue and de-peg it from the dollar.It had climbed 6.9 percent against the dollar in the past year, but some US critics say it remains undervalued, giving Chinese exporters an unfair advantage and resulting in the massive trade imbalance between the two countries.China was not against revaluation of the yuan, but opposed "excessively rapid" appreciation that was inappropriate to its national conditions, Commerce Minister Chen Deming said last month.Premier Wen Jiabao also said China would improve the yuan's exchange rate mechanism in a controllable and gradual manner, let the market play a bigger role in the mechanism and enhance the currency's flexibility.
