WASHINGTON, Dec. 16 (Xinhua) -- The U.S. International Trade Commission (USITC) Friday launched a probe into certain products from China after several U.S. companies alleged their patents were infringed.The products in question include televisions and Blu-ray players produced by Haier Group of China and Vizio Inc. under Taiwan-based Amtran Technology Company and sold in the U.S. market, the USITC said.` Five U.S. technology companies filed a complaint with USITC last month, saying those products violated Section 337 of the Tariff Act of 1930 by infringing their patents.Meanwhile, they requested the USITC issue an exclusion order and a cease and desist order against those products from China.The trade panel is scheduled to set a target date for completing the investigation within 45 days after institution of the probe. If the complaint is approved, the agency will ban importation of those products.The U.S. move came at a time when protectionism is making a comeback in the United States amid sluggish economic recovery.It is widely believed that such actions would only hurt U.S.- China trade relations that are increasingly critical to global economic recovery.

BEIJING, Jan. 1 (Xinhua) -- State Grid Corporation of China (SGCC), the country's largest power supplier, said Sunday it has put to trial operation a cross-border electricity transmission project in northeastern Heilongjiang province to supply Chinese with Russia's electric power exports.The electric power SGCC purchased from Russia began reaching Chinese customers late Saturday night after the completion of the direct-current back-to-back networking substation, or called "the trans-Amur project" by Russians, SGCC said in a statement on its website.The trial operation will last 168 hours, SGCC said in the statement.With a transmission capacity of 750 mega-watts, the electricity transmission project is China's biggest cross-border power line, according to SGCC."The implementation of the project will gain experience for the expansion of Sino-Russian energy cooperation and help promote the economic development for both countries," SGCC said.The project is also part of the Sino-Russian energy and trade cooperation.Russian Deputy Energy Minister Andrei Shishkin said in June 2011 that the transmission project would increase Russia's power supply to five or six billion kilowatt hours of electricity to China and Russia intended to increase its electricity supply to China in the coming years.Russian companies plan export 60 billion kwh of electricity to China by 2020. Power plants will be built along its border with China to reduce power transmission losses and reduce transportation costs.Also on Sunday, an oil pipeline linking Russia's far east and northeast China witnessed its one year anniversary of operation, as operators announced an accumulated 15 million tonnes of oil had been transported into China in 2011.

BEIJING, Jan. 20 (Xinhua) -- China will regulate the production and sale of cosmetic colored contact lenses by including them in its list of items classified as "medical apparatus."Some people wear such non-corrective colored contacts to change or enhance eye color for cosmetic and fashion purposes.As these contacts are not for vision correction and medication purposes, they are currently off limits to the country's medical administration and regulators, said a statement published on the website of the State Food and Drug Administration on Thursday.However, with the increasingly popular use of cosmetic contacts, safety and quality problems due to the regulation loophole are likely to harm consumers' health, and the administration has decided to expand the current medical regulation on contact lenses to cover cosmetic ones, the statement said.It explained that the administration will soon issue a notice to ban the manufacture and sale of these contacts without proper registration and licenses.The statement also warned consumers of the risks of these contacts and suggested they carefully choose and use such products.

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.

SAN FRANCISCO, Jan. 26 (Xinhua) -- Global tablet shipments reached nearly 27 million units in the fourth quarter of 2011 with Android jumping to a record share of 39 percent, said a new research released on Thursday.According to the research by consulting firm Strategy Analytics, global tablet shipments reached a record high of 26.8 million units in the last quarter of 2011, surging 250 percent from 10.7 million units in the same period a year earlier.Android captured a record 39 percent share of global tablet shipments, rising from 29 percent in the year-ago quarter.Global Android tablet shipments tripled annually to 10.5 million units in the last three months of 2011 and the platform so far is relatively popular with tablet manufacturers, said the research.However, Apple shipped 15.4 million iPads worldwide and maintained its market leadership with 58 percent share during the fourth quarter last year."Apple shrugged off the much-hyped threat from entry-level Android models this quarter," Peter King, director at Strategy Analytics, said in a statement.The research found Microsoft captured a mere 1.5 percent global tablet share in the quarter, noting that "the upcoming release of Windows 8 this year cannot come quickly enough for Microsoft, so its hardware partners can start competing more effectively in the tablet space."In the full year of 2011, global tablet shipments hit 66.9 million units, increasing by 260 percent from 18.6 million units in 2010, according to the research.Consumers are increasingly buying tablets in preference to netbooks and even entry-level notebooks or desktops, said the research.
