WINDHOEK, Nov. 29 (Xinhua) -- An agreement on Economic and Technical Co-operation was signed here on Tuesday between the Chinese and Namibian governments.The agreement was signed after Namibian Cabinet ministers and officials from various ministries held talks with Chinese State Councilor Liu Yandong, who arrived in Namibia on Tuesday for a three-day official visit.Minister of Presidential Affairs Albert Kawana, who is the Acting Director-General (DG) of the National Planning Commission (NPC), and Ambassador of China to Namibia Wei Ruixing signed the agreement.The two also exchanged letters on the provision of office supplies and solar energy equipment to the Namibian government by the Chinese government.During their talks, Liu highly spoke of the steady, healthy development of the relations between the two countries.She said the substantial cooperation have been obtained on agriculture, mining and human resources. Great achievements have been made in exchanges of culture and education.The state councilor also said China would like to work together with all African countries including Namibia to promote the development of people-to-people exchanges.Namibia's Deputy Prime Minister Marco Hausiku proposed future cooperation with China in visual and performing arts.He said the Directorate of Arts in the Ministry of Youth, National Service, Sports and Culture is keen to develop future relationships that will lead to bilateral exchanges in arts education, assistance in the development of small arts businesses, the promotion of arts through the exchange of information on arts and participation in events in the respective countries."This can be achieved through the development of ties between the relevant institutions responsible for these areas, such as the line ministries responsible for arts, arts education colleges, performance theaters, art galleries and organizers of events such as festivals and expos," he noted.He also encouraged exchanges between musicians in the sphere of composition, conducting, and instrumental playing in both folklore and symphonic genres, and therefore invited China in the development of Namibia's National Symphony Orchestra.Hausiku also proposed for scholarships in information and communication technology (ICT), particularly policy development and regulatory framework, and linkages with Chinese ICT institutions for exchange purposes.

BEIJING, Dec. 28 (Xinhuanet) -- China started to run its own satellite positioning system, Beidou, on Tuesday as the country climbed the global tech ladder and challenged the monopoly of the West. Beidou, or Big Dipper, the domestic version of the US Global Positioning System (GPS), started providing navigation, positioning and timing data on a pilot basis to China and the neighboring area for free on Tuesday, Ran Chengqi, director of the China Satellite Navigation Office, said. The system, with 10 orbiting satellites, covers an area from Australia in the south to Russia in the north. Signals can reach the Xinjiang Uygur autonomous region in the west and the Pacific Ocean in the east, Ran said. With six more satellites to be launched next year, the system will cover a wider area and eventually the entire globe by 2020 with a constellation of 35 satellites, he said. The accuracy of the positioning service will also improve as more satellites orbit. During the trial run Beidou can offer positioning to within 25 meters but when the system is officially launched next year accuracy will be enhanced to within 10 meters, he said. With the system operational China is the third member of an elite group, along with the US and Russia, to develop a satellite navigation system. The US spent 20 years and more than billion on the GPS. Completed in 1994, the system has 24 navigation satellites and is widely used around the world. Beidou has its own unique features, Ran said. "It not only tells users where they are and what time it is but also allows users to tell others the information through short messages," Ran said, adding that this feature is being considered by other systems. Russia's Glonass system achieved a 24-satellite constellation in 1996 but succumbed to funding problems. The rebuilding of the Glonass system is almost finished and Russian media reported that the system resumed service earlier this month. The European Union and the European Space Agency are building the Galileo satellite navigation system. Japan and India also intend to build independent regional navigation systems. "Countries build their own systems because owning an independent satellite navigation system is important to economic development and national security," said Pang Zhihao, deputy editor-in-chief of the monthly publication Space International. There have long been concerns that the US might take its dominant GPS offline in certain international emergencies. Ran said that the Beidou system will be "helpful" to national defense. An "independent and controllable" satellite navigation system can guarantee national economic development as well as scientific and industrial strength, he said. China started to reduce its reliance on the GPS in 2000, when it sent an experimental pair of positioning satellites into orbit. But Ran stressed that Beidou is "built for the world", as the compatibility of various systems enhances reliability for users. "If you only use GPS there will be blind spots. But from demonstrations I saw recently, receivers that are compatible with Beidou will overcome these problems," he said. He encouraged enterprises at home and abroad to join the research and development of application terminals compatible with Beidou. The office put a test version of the system's Interface Control Document online on Tuesday, which is a technical document vital for the manufacturing and development of receivers and chips. The prospects for the country's satellite navigation industry look bright, experts said. Analysts estimated that around 2020 the industry's output will reach 0 billion globally, including 400 billion yuan ( billion) to 500 billion yuan from China. According to the 2011 Report on Application of Geosaptial Information in China released on Monday, the number of satellite navigation application terminals in China has grown from less than 100,000 in 2000 to more than 10 million in 2009. The number is expected to reach 340 million by 2015. An insider said a compatible receiver for car use costs 1,600 yuan to 3,000 yuan, higher than a GPS receiver. "Chips supporting both GPS and Beidou systems have been developed, and terminals have been produced. There are no technical hurdles for the industry," said Han Shaowei, CEO of Beijing-based Unicore Communications Inc, a major navigation chip and core component provider. Beidou application terminals have been put into use in vehicles, such as government cars in Guangdong province. Ran said that private terminal makers in Guangdong are testing their receivers on the road, and the products seem stable. "The price of the compatible terminals is expected to be slashed next year," he said.

BEIJING, Nov. 25 (Xinhua) -- The BRICS members should make joint efforts to help ease tension in the Middle East and support the region's countries in carrying out political transition and social reconstruction on their own, Chinese Foreign Ministry spokesman Liu Weimin said Friday.Liu made the remarks at a daily press briefing, after Vice Foreign Minister Zhai Jun attended a deputy foreign ministers' conference of the BRICS in the Russian capital of Moscow on Thursday.The BRICS countries' enhanced communication and coordination, joint maintenance of the basic principles of international law, and opposition to foreign armed interference in the region are in line with the common interests of Middle East countries and the international community, Liu said."China will make concerted efforts with the international society, including BRICS members, to make constructive contribution to the Middle East's peace, stability and development," Liu said.The spokesman quoted Zhai Jun as saying at the Moscow conference that the Middle East's situation has a significant impact on international politics, economy and security in addition to the impact on the political and social situations in the region.It conforms with the common interests of the region's countries and the international community for the Middle East to be politically open and inclusive, independent in foreign policy, sustainable in economic development, and peaceful and stable in security matters, Zhai was quoted as saying.Liu Weimin said a joint communique was issued at the Moscow conference. The communique called on various parties to respect the state sovereignty and territorial integrity of the Middle East countries, have extensive dialogues by peaceful means, and make active efforts to seek solutions to the crisis.The BRICS members oppose the interference in the Middle East countries' internal affairs by foreign forces, advocate the positive role of the United Nations Security Council, and urge various parties to strictly observe the authorization of the UN Security Council, according to Liu.BRICS is an acronym for Brazil, Russia, India, China and South Africa.

WASHINGTON, Nov. 7 (Xinhua) -- U.S. researchers have demonstrated for the first time that the brain is a key player in regulating glucose (sugar) metabolism in humans.The findings, published Monday in the online edition of the Journal of Clinical Investigation, suggest that drugs targeting the brain and central nervous system could be a novel approach to treating diabetes."The brain is the body's only organ that needs a constant supply of glucose to survive, so it makes sense that it would have some say over how much glucose is produced," said study leader Meredith Hawkins, professor of medicine and director of the Global Diabetes Initiative at Yeshiva University, in a statement. "This role for the brain was demonstrated in earlier studies in rodents, but there was considerable controversy over whether the results could be applied to humans. We hope this study helps to settle the matter."In an earlier study in rodents, researchers showed that activation of potassium channels in the brain's hypothalamus sends signals to the liver that dampen its production of glucose. Those findings, published in Nature in 2005, challenged the conventional thinking that blood sugar production by the liver (the body's glucose factory) is regulated only by the pancreas (which makes insulin to metabolize glucose). But carefully performed studies on dogs, conducted at Vanderbilt University, failed to replicate the results, suggesting the Einstein findings in rodents might not be relevant to higher mammals, including humans.The current study, involving people, was aimed at resolving this controversy. Ten nondiabetic subjects were given oral diazoxide, a drug that activates potassium channels in the hypothalamus. (The drug is not used to treat diabetes.) Hormone secretion by the pancreas was controlled to ensure that any change in sugar production would only have occurred through the drug's effect on the brain. After the researchers administered the drug, blood tests revealed that patients' livers were producing significantly less glucose than before.Hawkins and her team then repeated this in rats, again giving diazoxide orally, achieving similar results. They confirmed that sufficient amounts of diazoxide crossed the blood-brain barrier to affect potassium channels in the hypothalamus. Additional experiments confirmed that diazoxide was working through the brain. Specifically, the researchers were able to completely block the effects of diazoxide by infusing a specific potassium channel blocker directly into the brain."This study confirms that the brain plays a significant role in regulating glucose production by the liver," said lead author Preeti Kishore, assistant professor of medicine. "We are now investigating whether this 'brain-to-liver' pathway is impaired in people with diabetes. If so, we may be able to restore normal glucose regulation by targeting potassium channels in the brain."

CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao met here Wednesday his French counterpart Nicolas Sarkozy on bilateral ties and other issues of common concern, including the Group of 20 summit scheduled for Thursday and Friday.Hu pointed out that since the global economic recovery is now burdened by quite a few instable and uncertain factors, the international community has great expectations of the G20 Summit in Cannes."The Chinese side actively supports the French side to host the summit," Hu said, emphasizing that the G20 should continue to uphold the spirit of cooperation and send a clear and definite signal of securing growth and promoting stability to the international community through this summit.Hu expressed the hope that all relevant parties should jointly endeavor to make the Cannes summit a conference of solidarity and win-win cooperation.Sarkozy expressed his appreciation of the effort China has made to prepare for the G20 summit. He said the French side was ready to strengthen coordination and cooperation with the Chinese side and work with all other parties to push for positive results at the summit.Hu said Europe is the largest economy in the world, and there will be no global economic recovery without a recovery of the European economy.He pointed out that the package deal that the European Union (EU) struck lately demonstrates its will and determination to resolve Europe's debt problem. He hoped that the implementation of the package deal would help overcome the difficulties facing Europe and be conducive to the recovery and growth of the European economy."It is mainly up to Europe to resolve the European debt problem," Hu said."We believe that Europe has all the wisdom and capability to resolve the debt problem," he added.Sarkozy said Europe is committed to resolving the debt crisis by making its own effort and strengthening cooperation with the international community. Hu said China wants to see Europe prosper.Noting that it was the third time for him to meet Sarkozy so far this year, Hu said the two sides had a frank and in-depth exchange of views on bilateral links, world economic situation, G20 affairs and major international issues and reached many important consensuses.The development of China-France relations has maintained good momentum recently. President Hu paid a state visit to France in November last year and met Sarkozy in March and August this year when the French president visited China.Hu said China places importance on developing its relations with France and the EU. He also thanked Sarkozy for France's meticulous preparation for the G20 summit and its hospitality to global leaders.France values China's role and appreciates its focus on major international issues, Sarkozy said, adding that his country is willing to maintain close communication and consultation with China.
