SHANGHAI, Nov. 16 (Xinhua) -- U.S. President Barack Obama on Monday called on the Chinese and U.S. governments to strengthen cooperation in dealing with such global challenges as climate change.     "There are very few global challenges that can be solved unless China and the United States agree," he stressed while answering a question at a town hall with Chinese students in Shanghai, the first stop of his four-day China tour.     As the world's two largest greenhouse gas emitters, the United States and China should assume the responsibility to curb greenhouse gas emissions, he said.     "Unless both of our countries are willing to take critical steps in dealing with this issue, we will not be able to resolve it," Obama said.     The president called on world leaders to strike a deal at the December Copenhagen conference during which they would make differentiated commitments to reducing greenhouse gas emissions.     China should not take the same obligations as the United States since it has a much larger population living in poverty, he said.     Climate change is expected to be one of the main topics at the upcoming meeting between Obama and Chinese President Hu Jintao.     President Hu promised at a September UN climate summit in New York that China would cut carbon dioxide emissions per unit of gross domestic product by "a notable margin" by 2020 from the 2005level.     Obama has said he wants to cut U.S. emissions back to 1990 levels by 2020 and 80 percent further by 2050, but the U.S. Congress was unlikely to complete climate legislation by the time of Copenhagen, due to great political challenges in the midst of a recession with high unemployment and other domestic priorities.     According to U.S. top negotiator Jonathan Pershing, it would be difficult for the U.S. to pledge an emissions target without legislation by Congress, therefore a new pact to combat global warming is a forlorn hope for Copenhagen.     The Dec. 7-18 Copenhagen meeting, which is expected to bring together leaders from 190 countries, aims to renew greenhouse gas emissions reduction targets set by the Kyoto Protocol, due to expire in 2012. 

BEIJING, Dec. 27 (Xinhua) -- China would not yield to pressure for the appreciation of its currency yuan, or renminbi, in any form, Chinese Premier Wen Jiabao said Sunday.     "A stable Chinese currency is conducive to the international community," Wen told Xinhua in an exclusive interview.

BEIJING, Dec. 18 (Xinhua) -- Chinese President Hu Jintao recently called for the whole nation to make further advancement in reform of the cadre and personnel system.     Vice President Xi Jinping, also a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, made the indications on the issue as well, noting that more achievement should be made in building a scientific cadre's selection and appointment system.     The CPC central committee has approved the outline of deepening the reform of cadre and personnel system (2010-2020) and it has been formally released. The plan put forward the goal and major tasks of the reform in next ten years.     The plan stressed the importance in dealing key issues concerning leadership and cadre cultivation, in making correct standard of cadre appointment and in improving the public credibility of cadre selection.

BEIJING, Oct. 29 (Xinhua) -- Sino-U.S. ties have been warmed up for U.S. President Barack Obama's upcoming China visit by frequent contacts between high-level officials from both sides, Chinese experts said Thursday.     The 20th meeting of China-U.S. Joint Commission on Commerce and Trade (JCCT) was officially convened on Thursday morning in China's eastern city of Hangzhou.     This year's JCCT talks, highlighted by U.S. Commerce Secretary Gary Locke, Trade Representative Ron Kirk and Agriculture Secretary Tom Vilsack, were widely seen as part of preparations for the presidential summit next month.     "Today's JCCT meeting laid a solid groundwork and made full preparations for President Obama's visit in two weeks, which will help build the positive, cooperative and comprehensive China-U.S. relations toward the 21st century," China's Minister of Commerce Chen Deming said at the end of talks.     In the meantime, Xu Caihou, vice chairman of China's Central Military Commission, was paying his first visit to the United States under the Obama administration.     During his talks with U.S. Secretary of Defense Robert Gates, Xu and Gates explored ways to further military-to-military cooperation and reached agreement on seven points, which included Gates' visit to China in 2010 and mutual visits of warships.     The agreement on conducting joint maritime searches and rescue exercises has already had the embryonic form of crisis management mechanism, said Ding Xinghao, president of the Shanghai Association of American Studies.     During the 11-day visit, the Chinese general was also invited to visit some sensitive military sites, including the Strategic Command Headquarter, which was in charge of nuclear weapons and cyber war.     Xu's visits to the sensitive military sites showed the U.S. military's willingness to promote mutual trust with the Chinese military, said Fu Mengzi, a researcher with the China Institute of Contemporary International Relations.     Since the Obama administration took office, Sino-U.S. relations have witnessed a smooth transition and maintained a good momentum of development.     In June 2009, the defense ministries of China and the United States held the 10th defense consultation. In July, the two countries held their first round strategic and economic dialogue. In August, the two militaries held the maritime military security consultation.     In addition, Obama issued a "presidential determination" On Sept. 29 that shifted authority for approving sales to China of missile and space technology from the White House to the Commerce Department, a move viewed by experts as Washington's delivery of goodwill to Beijing.     It was also noteworthy that U.S. Deputy Secretary of State James B. Steinberg proposed a new term to describe U.S.-China relations in his keynote address entitled "Administration's Vision of the U.S.-China Relationship" at the Center for a New American Security in Washington on Sept. 24.     "Strategic reassurance", as Steinberg noted, means that "just as we and our allies must make clear that we are prepared to welcome China's 'arrival'...China must reassure the rest of the world that its development and growing global role will not come at the expense of security and well-being of others."     This term captured the crux of Sino-U.S. ties, said Niu Xinchun, vice director of the Center for American Studies at the China Institute of Contemporary International Relations. "It is aimed at realizing the strategic mutual trust between the two countries."     The foundation for the sustained and stable development of bilateral ties lies in mutual trust, he said, but trade frictions between the two nations show that mutual trust still needs to be strengthened.     Obama announced in September to impose 35 percent punitive tariffs on all car and light truck tires from China for three years.     Just on Tuesday, the U.S. Department of Commerce announced preliminary determination that intended to impose a tariff up to 12 percent on the steel grafting and steel strand imported from China, valued 269 million U.S. dollars.     In addition, China and the United States still have differences on some issues concerning China's core interests, such as U.S. arms sales to Taiwan and Tibet-related issues.     Although both sides have the willingness to enhance mutual trust, it is still difficult for them to fulfill the goal, said Fu Mengzi, adding it needs sustained efforts from both sides.     "Sino-U.S. relations are now standing at a new historical starting point," said Chinese Vice Premier Wang Qishan at the opening ceremony of the 20th JCCT meeting. "President Obama's first China visit will surely provide new opportunities for bilateral cooperation."

SHANGHAI, Nov. 16 (Xinhua) -- Visiting U.S. President Barack Obama said Monday that different countries should learn from each other to diversify cultures in the world.     "Each country in this interconnecting world has its own culture, its own history, and its own traditions," Obama said during a dialogue with Chinese students in the Shanghai Science and Technology Museum.     "It is very important for the United States not to assume what is good for us is automatically good for somebody else," he said when responding to a question raised by a Shanghai college student about how to promote cultural exchanges between different countries. U.S. President Barack Obama gestures as he delivers a speech at a dialogue with Chinese youth at the Shanghai Science and Technology Museum during his four-day state visit to China, Nov. 16, 2009    Obama said one of the U.S. strengths is the country has a very diverse culture, and has people coming from all around the world. "There is no one definition of what America looks like," he added.     He cited his family as an example of diverse cultures, saying the family is like "the United Nations" as his father was from Kenya, his mother from Kansas of the U.S. Midwest, while his sister was a half-Indonesian married to "a Chinese person from Canada."     Obama flew into Shanghai from Singapore on Sunday night to kickoff his four-day visit to China, his first trip to the Asian country since taking office in January.     Later Monday, he will fly to Beijing, where he will hold talks with Chinese President Hu Jintao and meet with other Chinese leaders.
