ADDIS ABABA, Dec. 2 (Xinhua) -- Xie Xiaoyan, the newly appointed Chinese ambassador to Ethiopia and the African Union (AU) on Friday presented his letter of credence to Jean Ping, chairperson of the AU Commission (AUC) at his office in Addis Ababa, Ethiopia.After presenting the credential letter to Ping at the AU headquarters, Ambassador Xie held talks with the AUC chief on the relations and cooperation between China and the union of 54 member countries.The Chinese government has constructed a state-of-the-art office complex and conference hall for the AU with an outlay of around 125 million U.S. dollars, a project that demonstrates the friendship between China and Africa.

WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

BEIJING, Oct. 28 (Xinhuanet) -- Taking aspirin everyday may lower the risk of developing colon cancer for people with the cancer-causing genes, researchers found.The finding was published on Friday in the British medical journal "Lancet".The researchers followed 508 patients with Lynch syndrome, an inherited disorder which increases the risk of developing colon and other cancers.These patients were divided into two groups: members in one group took 600 mg aspirins everyday; another group took only the dummy pills.After 4 years, 10 colon cancer cases were reported among 258 patients who took daily aspirins for at least two years, comparing with 23 cases among 250 patients on dummy pills."This is good news for a very specific population," said Asad Umar, a cancer prevention expert at the U.S. National Cancer Institute.However, the finding doesn't apply to the general public, suggested the lead author of the study John Burn, a geneticist at Newcastle University in England.Only those who are at risk of such diseases should consider taking aspirin regularly, such as people having a family history of colon cancer, he added.

BEIJING, Oct. 26 (Xinhua) -- The central government allocated 935 million yuan (147 million U.S. dollars) Wednesday to areas hit by rain-triggered floods, the Ministry of Civil Affairs (MCA) said.The relief funds, jointly allocated by the MCA and the Ministry of Finance, will be used for disaster survivors to relocate, rebuild houses and buy daily necessities.The funds will also be delivered to the family members of the victims, according to the ministry.The funds will go to the flood-hit provinces of Shanxi, Henan, Hubei, Sichuan, Shanxi and Guangxi Zhuang Autonomous Region.The government already allocated 132 million yuan (20.6 million U.S. dollars) to disaster hit areas immediately after the floods happened in September.Rain-triggered floods and disasters left 97 people dead, 21 missing and 1.23 million affected in September in China's 11 provincial-level regions, and a total of 1.93 million people were relocated urgently to avoid further casualties.The disasters also caused an estimated 21 billion yuan (3.29 billion U.S. dollars) in direct economic losses, according to official data.

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.
