BEIJING, March 21 (Xinhua) -- Renowned Chinese liquor producer Kweichow Moutai Co., Ltd. announced Monday its annual net profit in 2010 rose 17.13 percent year on year on strong market demand.Its net profit hit 5.05 billion yuan (769.17 million U.S. dollars), the Guizhou-based firm said in its 2010 annual report filed to Shanghai Stock Exchange.The company's annual business revenue increased 20.3 percent from one year earlier to 11.63 billion yuan while earnings per share stood at 5.35 yuan.The economic rebound accelerated the development of liquor industry despite rising raw material prices, said the report.The A-share price of the upmarket distiller opened down 0.70 percent from the previous close to 189.8 yuan Monday.

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."

BEIJING, May 5 (Xinhua) -- A Chinese official has vowed to take every possible measure to ensure food safety in the country, saying the government has decided to launch national overhauls this year on sectors including milk products, cooking oil, health foods, meat and alcohol.Zhang Yong, director of the executive office of the food safety commission under the State Council, or Cabinet, said in an interview with Xinhua that the food and drinks in these five sectors are consumed in enormous quantities each day and they will do great harm and have an extensive social impact if a problem arises.Through special campaigns to overhaul these five sectors and by solving the most prominent problems, the government aims to accumulate experiences and create administrative systems in a bid to prevent food safety incidents and raise the overall level of food safety, Zhang said.The central government initiated a prolonged and stringent fight against the illegal use of additives in food last month, detailing measures to intensify supervision, upgrade safety limits, and increase penalties for violators.Vice Premier Li Keqiang warned of the great harm from illegal additives in food at a high-profile national meeting last month, promising a "firm attitude, iron-hand measures and more efforts" in dealing with the problem.Zhang Yong admitted "China is in a period when food safety incidents are likely to arise" since the country's food industry is on a fast track for development and a large number of food producers and catering operators are running their businesses in a small-scale or scattered way."It makes it more difficult for the government departments to conduct supervision on food quality and safety," Zhang said."We will take every possible measure to consolidate the feeble foundation to ensure food safety and curb food safety incidents as soon as possible," he said.According to Zhang, the government will also make efforts to improve supervision and emergency handling capabilities, raise the credibility and personnel quality of the involved enterprises, and severely punish violators.The Chinese government made the moves after a series of food safety scandals emerged despite the authorities' efforts to revamp the country's food industry. They included steamed buns dyed with unidentified chemicals, the use of "lean meat powder", also known as clenbuterol, a kind of fat-burning drug, as well as the use of illegal cooking oil known as "gutter oil."

CAPE TOWN, April 30 (Xinhua) -- The World Economic Forum on Africa, scheduled on May 2-4 in Cape Town, South Africa, will see participants exchange views on how the continent can turn to the next chapter of development.The meeting, expected to gather a record 900 participants from over 60 countries, will be held under the theme "From Vision to Action, Africa's Next Chapter," organizers said."We chose this theme because we feel it is very relevant for the events that are taking place on this continent, and the opportunity for growth and investment that the international and African communities are seeing," said Katherine Tweedie, head of Africa for the World Economic Forum.Seven of the fastest growing economies in the world in the next five years will be in sub-Saharan Africa, Tweedie noted, saying that a lot of discussion will be devoted to explore drivers behind this growth.Africa's economic growth in recent years have impressed the world. Though being the most underdeveloped continent, Africa have been more resilient than expected during the global economic crisis.The International Monetary Fund (IMF) have predicted that the continent's growth in 2011 will reach 5.3 percent.Under one of the three thematic pillars, "Shaping Africa's Role in the New Reality," the meeting will explore how Africa can take on a leadership role in the new reality and guard against newly emerging global and regional risks. Participants will look at how Africa can strengthen its representation and negotiation capacity on global platforms such as COP 17 and the G20.Meanwhile, the meeting will look into Africa's industrial diversification, which is widely considered as an effective way to increase competitiveness. Discussions under the thematic pillar of "Fostering Africa's News Champions of Growth" will focus on what innovative and entrepreneurial lessons drive Africa's fastest- growing companies, and how can Africa's emerging economies build capacity in science, technology and innovation to move up the value chain.Another topic expected to attract much attention is Africa's inclusive development. In recent years, African decision makers have been looking for ways to attain inclusive development by translating economic growth into better lives for the people.Marcus Courage, managing director of consulting group Africapractice, said ahead of the meeting that Africa must start measuring its economic growth in terms of job creation and progress of value addition of what it produces, rather than the gross domestic product (GDP), if it has to move from vision to action."One of the challenges is that we measure economic success in therms of GDP. That is not fair reflection of action," he told Xinhua.Under the thematic pillar of "Building Partnership for Inclusive Development," participants will debate on how can inclusive growth be put at the heart of a sustainable development agenda for Africa, and how can government of African countries work together with the business sector to distribute more equitably the benefits from the wealth in natural resources, among others.Regarding the highlight of this year's meeting, Tweedie said there will be a strong focus on green growth and the environment agenda, working closely with the South African government, given that South Africa will be hosting the COP 17 meetings in December.The meeting will also have very strong representation from Francophone west Africa for the first time. As a result a good part of the discussions will be focusing on issues taking place in this part of Africa, she added.Although South Africa has hosted the World Economic Forum on Africa for a number of times, this year the host is attracting particular attention.South Africa has joined the BRICS group of countries which also include Brazil, Russia, India and China, becoming the only African member in the grouping. It is also the only country from Africa in G20. In November this year, South African city of Durban will host the 17th Conference of the Parties (COP 17) to the UN Framework Convention on Climate Change.How can the country speak for Africa in the international arena, and what role can it play in facilitating closer cooperation between developing countries is also expected to draw in-depth discussions at the meeting.Meanwhile, participants are also expected to exchange views on issues including Africa's agriculture development, infrastructure construction, China-Africa cooperation, impact of political situation in North African and the Middle East on Africa's economic development, among others.

BEIJING, Feb. 5 (Xinhua) -- China's meteorological authority said Saturday that a cold snap would sweep north China over the next few days, bringing down temperatures and carrying gusty winds.Temperatures in some parts of Xinjiang Uygur Autonomous Region, Inner Mongolia Autonomous Region and northeast China will drop 4 to 6 degrees Celsius over the weekend, the National Meteorological Center (NMC) said in a statement on its website.In most areas north to the Huaihe River, the temperatures will go down 4 to 6 degrees Celsius, or even 8 to 10 degrees Celsius in some parts of the areas between Monday and Tuesday.The cold front would then move southward to affect more areas in the eastern and southern parts of the country.The NMC said some areas in northern and western Xinjiang Uygur Autonomous Region, the eastern part of Inner Mongolia, Sichuan Basin and most of the northeast China, the western parts of the areas south to the Yangtze River will see light to moderate snow or sleet in the forthcoming three days.Fog continued to shroud south China Saturday, reducing visibility to less than 200 meters in parts of Hunan, Hubei, Jiangxi, Sichuan and Fujian provinces, as well as Chongqing City.
