BEIJING, Dec. 11 (Xinhua) -- China is faced with severe challenges in collecting enough blood plasma to produce medicines, Health Minister Chen Zhu said Sunday.Chen called on the public to join blood donation after donating blood plasma at the Beijing Red Cross Blood Center on Sunday, the fifth time since he took office in 2007.Blood plasma is needed to make blood products like prothrombin complex which is vital for hemophiliacs.The total volume of blood plasma collected last year was 4,180 tonnes, while the volume needed to produce enough medicines was 8,000 tonnes, said a statement from the ministry. The situation became even worse this year.Donations of blood plasma in China fell dramatically in recent years, as a result of safety concerns from donors and the government's efforts to regulate blood collection after contamination triggered HIV infection scandals.In an overhaul of plasma collection services in 2004, the ministry closed 262 donation centers, leaving only 138 in operation, resulting in the plasma donations falling at least one-third from 5,000 tonnes in 2003.Blood plasma are currently collected at 144 designed stations across the mainland. The stations, as requested by law, are all owned by major manufacturers of blood products.Chen promised to encourage qualified drug makers to set up more collection stations in the next five years.He also assured the public the safety of blood donation at authorized stations.

SAN FRANCISCO, Dec. 2 (Xinhua) -- Only two weeks after its shipment, Amazon's Kindle Fire has already shown the momentum to grab the second place in global tablet computer market, research firm IHS predicted on Friday.Amazon is expected to ship 3.9 million Kindle Fire tablets during the last three months of 2011, the first quarter the product goes on sale, according to preliminary projection from IHS.The number will give Amazon a 13.8-percent share of global tablet market in the fourth quarter, surpassing the 4.8 percent held by No. 3 player Samsung, and second only to Apple's commanding 65.6 percent market share."Nearly two years after Apple Inc. rolled out the iPad, a competitor has finally developed an alternative which looks like it might have enough of Apple's secret sauce to succeed," Rhoda Alexander, senior manager of tablet and monitor research for IHS, said in a statement."Initial market response strongly suggests that Amazon, with the Kindle Fire, has found the right combination of savvy pricing, astute marketing, accessible content and an appropriate business model, positioning the Kindle Fire to appeal to a brand-new set of media tablet buyers," she added.IHS analysts noted that with a price tag of 199 U.S. dollars, the Kindle Fire has set a new bar for pricing, bringing the tablet within reach of a larger portion of the buying public.IHS expects Kindle Fire's rapid ascent to help fuel the expansion of the entire tablet market, now predicting that 64.7 million tablets will be shipped in 2011, higher than its previous forecast of 60 million issued in August.The total tablet shipment number this year will represent a 273- percent growth from 17.4 million units in 2010, said IHS, which has also increased its longer-term projection of global tablet shipment in 2015 to 287.2 million units.

WASHINGTON, Nov. 29 (Xinhua) -- China and the United States on Tuesday held high-level talks on enhancing cooperation on anti- monopoly and anti-trust enforcement, with an aim to strengthen the bilateral economic and trade relations.This was the first time that the two sides held such meeting since they signed in last July a memorandum of understanding (MOU) on anti-monopoly and anti-trust enforcement cooperation by related enforcement agencies from the two countries.Gao Hucheng, China's International Trade Representative and Vice Minister of the Ministry of Commerce, led the Chinese delegation to the talks with the U.S. delegation headed by Jon Leibowitz, chairman of the U.S. Federal Trade Commission, and Sharis Pozen, acting Assistant Attorney General of the Department of Justice in charge of anti-trust affairs.The two sides briefed each other on the latest developments on the anti-monopoly and anti-trust policies and their enforcement in own country, while discussing ways to further strengthen anti- monopoly and anti-trust enforcement in related industries, during a time of economic downturn.They also reached an agreement on the guidelines of cooperation on pursuing anti-monopoly and anti-trust enforcement in individual cases, such as mergers of corporations, after reviewing the bilateral exchanges and cooperation in this field.It was agreed that the China-U.S. economic and trade relations are the cornerstone of the overall bilateral relationship, and the enforcement of anti-monopoly and anti-trust laws can help secure the smooth development of their economies, to the benefits of both countries and peoples.Such talks are conducive to enhancing mutual understanding of each other's practices in formulating and enforcing anti-monopoly and anti-trust policies, through sharing experiences and increased cooperation, the two sides agreed.In July, three Chinese anti-monopoly law enforcement agencies, the National Development and Reform Commission, Ministry of Commerce and State Administration for Industry and Commerce, signed the MOU on cooperation in anti-monopoly and anti-trust enforcement, with the U.S. Department of Justice and Federal Trade Commission.The document is a long-term framework between China's anti- monopoly enforcement agencies and their U.S. counterparts, designed to promote better enforcement of competition laws and regulations of the two countries. Under the MOU, the two sides will hold high-level consultations, exchange of information on law enforcement and policies, as well as cooperation on specific cases, mainly for mergers.
