CHONGQING -- A bus fire that killed 27 people in southwest China's Chongqing Municipality on Tuesday had been an arson attack, local police said on Wednesday.Xiao Yonghua, a former employee of the company that operates the ill-fated Yutong bus, hid gasoline in his baggage before he got on the bus that left Wansheng district for downtown Chongqing at around 5:00 pm on Tuesday, said Wang Yunsheng, deputy head of the municipal public security bureau.In less than 20 minutes, the bus carrying 38 people caught fire. The driver pulled over, and the panic-stricken passengers tried to flee. But the flames started in the front of the bus and blocked the exit.Twenty-seven were killed in the accident, including 17 men and 10 women, and the remaining 11 people were injured.One passenger, Zhang Dazhong, said he had to jump out of the window to survive but was injured on the head.Xiao, 50, was sitting with his wife, 38-year-old Zhang Xiaoya, in the first row on the left side of the bus, right behind the driver, said Wang.Both died in the fire.Lab work has confirmed the presence of gasoline traces on their seats.Until September 20, Xiao was deputy manager of the Wansheng branch of the Guanzhong Public Transport Company that owned the bus.He was suspended from his post because of family disputes, and was unhappy with the punishment, the company said.The Ministry of Public Security sent experts to join the investigation in Chongqing.Hospital sources said the 11 injured are out of danger.By 5:00 pm Wednesday, 26 of the dead have been identified by their families.

The U.S. National Academy of Sciences announced on Tuesday the election of 72 new members and 18 foreign associates in recognition of their distinguished and continuing achievements in original research. The election was held this morning during the business session of the 144th annual meeting of the academy, and brought the organization's total number of active members to 2,025. Foreign associates are non-voting members of the academy. The 18 newly elected, from 12 different countries, brought the total number of foreign associates to 387. Two Chinese scientists, Zhang Qifa and Li Aizhen, were among the new foreign associates. Professor Zhang is the director of National Key Laboratory of Crop Genetic Improvement, Huazhong Agricultural University, in central China's Wuhan. Li is from the Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences.

The act calls on the academy to act as an official adviser to the federal government, upon request, in any matter of science or technology

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.

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."
