BEIJING, Sept. 30 (Xinhuanet) -- Tobacco companies concealed the knowledge of radioactive substance in cigarettes from public for over four decades, a new study revealed.The revelation was made by a research team from the University of California, Los Angeles, published on Thursday in the online edition of the U.S. medical journal Nicotine and Tobacco Research.The researchers analyzed 27 timeworn documents and discovered that tobacco companies had knew the existence of polonium-210, a hazardous radioactive substance, in the tobacco since 1959.The companies studied polonium-210 throughout the 1960s, and concealed their findings about the carcinogenic potential of the radioactive substance.Hrayr Karagueuzian, the study's lead author, said the tobacco companies' deception surprised him.According to the revelation, the companies had knew the "cancerous growths" in the lungs of smokers, and even calculated how much radiation a regular smoker would inhale over 20 years.Karagueuzian and his team conducted again the study recorded in the tobacco documents and found that the radiation in cigarettes would cause up to 138 deaths for every 1,000 smokers over a period of 25 years.However, tobacco manufacturer denied that they had concealed the facts from the public.David Sutton, spokesman of Philip Morris, the largest U.S. tobacco company, said the polonium-210 was a "naturally occurring element in the air" and had been widely discussed by the public health community for years.

BEIJING, Dec. 12 (Xinhua) -- A Foreign Ministry spokesman said on Monday that China welcomes the EU's new measures for coping with the European sovereign debt crisis worked out at the recently-concluded EU summit."We hope relevant measures can help stabilize the market, boost confidence in the market, stop the crisis from worsening, promote employment and economic growth, and push forward European integration," Foreign Ministry Spokesman Liu Weimin said at a routine press briefing.Last Friday at the summit in Brussels, EU leaders agreed on establishing a new "fiscal compact" based on inter-governmental treaties rather than the expected EU treaty changes. Britain opted out of the compact.Under the fiscal compact, member states will have to submit their draft budgetary plans to the European Commission, the EU's executive arm.As world's largest economy, the stable and healthy growth of the European Union and the Eurozone will be crucial to maintaining the momentum of recovery in the world economy, Liu said.China will maintain its support for EU integration, and continue to back the EU's efforts in combating the debt crisis in various ways, so as to jointly promote the stability of the international financial market and the recovery and growth of the world economy, he said."We are confident in Europe and the Eurozone, and believe that the EU has the ability and wisdom to resolve the sovereign debt crisis," Liu said.

BEIJING, Jan. 12 (Xinhua) -- China's consumer price index (CPI), a main gauge of inflation, rose 4.1 percent year-on-year in December, down 0.1 percentage point from November on falling non-food prices, the National Bureau of Statistics (NBS) said Thursday.The CPI was up 5.4 percent in 2011 from the previous year, well above the government's full-year inflation control target of 4 percent, the NBS said in a statement on its website.The inflation rate in December marked a five-straight-month decline after hitting a 37-month high of 6.5 percent in July amid government tightening measures, according to the NBS data.On a monthly basis, the cost of living dipped 0.2 percent in December, while prices of entertainment, educational and cultural articles and services dropped 0.3 percent, the NBS said.Food prices, which account for nearly one third of the basket of goods in the nation's CPI calculation, went up 9.1 percent year-on-year in December and 1.2 percent month-on-month, the NBS said.The December inflation figure was in line with the market expectation, as many economists forecast that the CPI would grow around 4 percent year-on-year in December.China's Producer Price Index (PPI), a major measure of inflation at the wholesale level, rose 1.7 percent in December year-on-year, further weakening from 2.7 a month earlier.China has made controlling prices a top priority last year and implemented a series of measures to address the issue, including tightening monetary policy, cracking down on speculation, increasing food supplies and reducing circulation costs.

BEIJING, Dec. 4 (Xinhua) -- Chinese President Hu Jintao sent a message to Venezuelan President Hugo Chavez and Chilean President Sebastian Pinera on Friday to congratulate the founding of the Community of Latin American and Caribbean States (CELAC).In his message, Hu said that the establishment of CELAC is a major milestone in regional integration and that China appreciates the positive role of Latin American and Caribbean countries in international and regional affairs.China believes that the establishment of the community will make important contributions to unity and coordination in the region as well as joint efforts to counter global challenges, Hu said.China and Latin America are geographically apart, but their peoples enjoy traditional friendship, Hu said.In the 21st century, relations between China and Latin America have seen all-round and fast development with the expansion of mutually beneficial cooperation, Hu said.China has always treated its relations with Latin America from a strategic perspective and China is willing to work with CELAC and other countries in the region to build and develop a comprehensive cooperative partnership of mutual benefit and common development through the strengthening of dialogue, communication and cooperation, said Hu.The idea of CELAC was initiated in February 2010 at a regional summit in the Mexican resort of Cancun. The new grouping represents all countries in the Americas except Canada and the United States.

SEOUL, Nov. 8 (Xinhua) -- Samsung Electronics, the world's largest flat screen TV vendor, said Tuesday that it has suspended its plan to develop active shutter three-dimensional (3D) TVs with RealD, the U.S.-based 3D technology supplier."Samsung has decided to focus on our own initiatives of 3D technology, and continues to research and develop next-generation 3D display technologies, including a glasses-free 3D solution for the home," the tech firm said in an e-mailed statement.The active shutter 3D technology drew public attention after Samsung reached a deal with RealD earlier this year to jointly develop such technology, aiming to unveil 3D TVs based on the technology early next year.The active shutter is a next generation 3D technology that incorporates merits from both shutter-glass (SG) technology, which Samsung adopted, and film patterned retarder (FPR) technology, which LG introduced in December last year.The SG technology has been touted as better picture quality and deeper 3D images, but the eyewear is heavier because it requires batteries and chips to work. The active shutter 3D technology moved its function of 3D image creation from eyewear to flat panel, making the eyewear lighter.Despite the upgraded technology and its convenience, Samsung decided to focus on its existing SG technology as the global TV market is grappling with weak demand. The penetration rate, which gauges the ratio of 3D sets against the total flat screen TVs, was expected to rise to 9.9 percent by year-end from the 3 percent a year earlier, according to Woori Investment & Securities, a local securities firm.
