ADDIS ABABA, Jan. 28 (Xinhua) -- The on-going political crisis in Cote d’Ivoire should be and can be solved peacefully, Chinese Envoy and Assistant Foreign Minister Liu Zhenmin told Xinhua here on Friday, ahead of the 16th African Union (AU) summit scheduled for Jan. 30-31.Liu was in the Ethiopian capital Addis Ababa, the headquarters of the 53-member African bloc, to attend the summit as special envoy of the Chinese government.Cote d'Ivoire has been trapped in a political impasse since the landmark presidential run-off held on Nov. 28. Both incumbent Laurent Gbagbo and opposition leader Alassane Ouattara claimed victory and swore themselves in as president, and formed their respective government.Gbagbo was backed by the country's Constitutional Council, while Ouattara has the support of the electoral commission and the international community including the United Nations (UN), the AU, the Economic Community of West African States (ECOWAS), the United States and France.China hopes various parties and stakeholders in Cote d’Ivoire can resolve their disputes through dialogues and consultations based on the interest of the country and its people, and maintain peace and stability, Liu said.A peaceful solution to the crisis is not only in the interests of the Ivorian people, but of the West African region as a whole, according to Liu.China appreciates the efforts made by the AU and ECOWAS to find a peaceful solution to the crisis, and will continue supporting Africa’s efforts to resolve the crisis peacefully, Liu said.According to the UN, more than 200 people have died from violence during the power struggle between Gbagbo and Ouattara.The 16th AU summit, to be held under the theme “Towards Great Unity and Integration Through Shared Values,” will gather heads of states and government from member states to discuss issues including Africa’s integration, and peace and security in the continent. The situation in Cote d’Ivoire, among others, is expected to top the agenda of the summit.

NEW DELHI, March 5 (Xinhua) -- Doctors in India have claimed to have successfully performed a rare robotic heart surgery on a 23- year-old person at a hospital in the southern Indian city of Chennai, local media reported Saturday.Dr. R. Ravi Kumar, the Director of the Institute of Cardiovascular Disease at the Chettinad Health City, said the robotically assisted procedure involved replacing both the mitral and the aortal valve simultaneously.The surgery carried out on D. Vijayakanth, an auto driver from Vellore, was done by a three armed robot, took four hours and cost 225,000 rupees (4,500 U.S. dollars)."The best part about using a robot in cardiac surgery is that the patient's heart need not be opened and the surgery can be done using a small 4cm incision. This is not possible with normal surgeries without a robot," Dr Ravi Kumar was quoted by local daily The Times of India as saying.Robotic surgery, which is fairly new in the country, can be used for a gamut of medical procedures, said Dr Ravi Kumar."It requires a lot of precision and intense training because though the robotic hands do the surgery, it has to be controlled by a trained surgeon. One of the biggest disadvantages is the lack of sensory perception which is there when the surgeon actually does the surgery himself," he said.

BEIJING, Feb. 2 (Xinhua) -- Two more planes flew 435 more Chinese back home from Egypt Wednesday afternoon.An airliner with 213 Chinese from Cairo landed at the Beijing Capital International Airport at 2:19 p.m., and another with 222 Chinese including many Hong Kong people from Luxor landed at a Hong Kong airport at 3:25 p.m..These flights were another strive of the Chinese government and airline operators to get stranded Chinese nationals out of Egypt, where anti-government demonstrations have led to chaos in several major cities including Cairo.So far, 1371 stranded Chinese had been taken home by six flights.

WASHINGTON, May 2 (Xinhua) -- Rice originated in China, a team of U.S. genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing.Their findings, which appear Monday in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin -- India as well as China.Asian rice, Oryza sativa, is one of world's oldest crop species. It is also a very diverse crop, with tens of thousands of varieties known throughout the world. Two major subspecies of rice -- japonica and indica -- represent most of the world's varieties. Sushi rice, for example, is a type of japonica, while most of the long-grain rice in risottos are indica.Because rice is so diverse, its origins have been the subject of scientific debate. One theory -- a single-origin model -- suggests that indica and japonica were domesticated once from the wild rice O. rufipogon.Another -- a multiple-origin model -- proposes that these two major rice types were domesticated separately and in different parts of Asia. The multiple-origin model has gained currency in recent years as biologists have observed significant genetic differences between indica and japonica, and several studies examining the evolutionary relationships among rice varieties supported more than domestication in both India and China.In the PNAS study, the researchers re-assessed the evolutionary history, or phylogeny, of domesticated rice using previously published datasets, some of which have been used to argue that indica and japonica rice have separate origins. Using more modern computer algorithms, however, the researchers concluded these two species have the same origin because they have a closer genetic relationship to each other than to any wild rice species found in either India or China.In addition, the study's authors examined the phylogeny of domesticated rice by re-sequencing 630 gene fragments on selected chromosomes from a diverse set of wild and domesticated rice varieties. Using new modeling techniques, which had previously been used to look at genomic data in human evolution, their results showed that the gene sequence data was more consistent with a single origin of rice.In the study, the investigators also used a "molecular clock" of rice genes to see when rice evolved. Depending on how the researchers calibrated their clock, they pinpointed the origin of rice at possibly 8,200 years ago, while japonica and indica split apart from each other about 3,900 years ago. The study's authors pointed out that these molecular dates were consistent with archaeological studies.Archaeologists have uncovered evidence in the last decade for rice domestication in the Yangtze Valley beginning approximately 8, 000 to 9,000 years ago while domestication of rice in the India's Ganges region was around about 4,000 years ago."As rice was brought in from China to India by traders and migrant farmers, it likely hybridized extensively with local wild rice," explained New York University biologist Michael Purugganan, one of the study's co-authors. "So domesticated rice that we may have once thought originated in India actually has its beginnings in China."

WASHINGTON, May 27 (Xinhua) -- The U.S. Treasury Department said in a report released on Friday that China was not manipulating its currency."In China, since the authorities decided in June 2010 to allow the exchange rate to appreciate in response to market forces, the renminbi (RMB) has appreciated by a total of 5.1 percent against the dollar in nominal terms through the end of April 2011, or at an annual pace of approximately 6.0 percent," noted the semi- annual report on international economic and exchange rate policies.The Treasury said that as inflation in China is significantly higher than it is in the United States, the renminbi has appreciated more rapidly against the dollar on a real, inflation- adjusted basis, at a rate of around 9 percent per year.The delayed report, which was originally scheduled to be sent to the Congress on April 15, finds "no major trading partner of the United States" manipulated its currency during the period covered in the report.The Treasury added that it will continue to "closely monitor" the renminbi appreciation pace.The report also noted that the U.S. economy is recovering from its deepest recession in the post-war period."While recent growth is encouraging, the economy still faces significant challenges," said the report. The number one challenge is still in the labor market.The U.S. unemployment rate, currently at 9.0 percent, is not expected to fall significantly this year.Besides, housing market and long-term fiscal position are " unsustainable," according to the report.In recent remarks, Treasury Secretary Timothy Geithner stated that China is the fastest growing market for U.S. exports. In 2010, U.S. exports to China grew at a pace that was 50 percent higher than the rest of the world.
