BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

BEIJING, May 21 (Xinhua) -- China may see increased planting acre of early rice this year, though drought has not been relieved in some areas, said a statement on the website of the Ministry of Agriculture on Saturday.China is expected to plant 88.5 million Mu (5.87 million hectares) of early rice this year, about 1.6 million Mu more than the previous year, thanks to soaring rice prices and policy incentives, the statement said.However, drought continues in Hubei Province, Poyang Lake areas in Jiangxi Province, Dongting Lake areas in Hunan Province and Leizhou Peninsular in Guangdong Province, the statement said.The drought has affected about 3 million Mu of paddies in Hubei in the middle reaches of the Yangtze River, the statement said.The statement urged local agricultural departments to help facilitate paddy management, as strong rains were forecast for southern China from Friday to next Tuesday.The middle and lower reaches of the Yangtze River received about 40 to 60 percent less rain this year than in previous years -- this year being the least amount of rain in the past 50 years, said the State Flood Control and Drought Relief Headquarters.

LOS ANGELES, March 27 (Xinhua) -- Walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut, U.S. researchers have found.Study findings were presented on Sunday at the 241st National Meeting & Exposition of the American Chemical Society (ACS) in Anaheim, Southern California.Nuts contain plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free, ACS researchers said in the study.Moreover, nuts contain healthful polyunsaturated and monosaturated fats rather than artery-clogging saturated fat, according to the study.The researchers based their conclusion on analysis of antioxidants in nine different types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias and pecans.They found that walnuts have the highest levels of antioxidants, with plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free.The latest study adds more evidence that walnuts are top nuts for heart-healthy antioxidants, the researchers said.Previous studies showed that regular consumption of small amounts of nuts or peanut butter can decrease the risk of heart disease, certain kinds of cancer, gallstones, Type 2 diabetes, and other health problems.But the latest study is the first to compare both the amount and quality of antioxidants found in different nuts."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who led the latest study."A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."

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."

MOSCOW, May 13 (Xinhua) -- The main and backup crews that will fly to the International Space Station in June have passed preflight tests and are ready for space travel, the Russian Cosmonauts Training Center said Friday.The main crew includes Russian cosmonaut Sergei Volkov, Japanese astronaut Satoshi Furukawa and American astronaut Michael Fossuma.A Russian spaceship Soyuz TMA-02M will send the crew to the space station on June 8, Interfax news agency reported.The backup crew includes members from Russia, the Netherlands and the United States.The crews were tested on the various emergency situations they could face during the flight.Next Monday, the commission will make a final choice of crewmembers for the launch.The crew will spend 161 days in orbit and conduct three space walks.
