SHENZHEN -- Construction began Saturday on an experimental facility which will offer a platform for Chinese and foreign scientists to work together for discovering a new kind of neutrino oscillation in Shenzhen, South China's Guangdong Province.It was the second biggest cooperation program Chinese high energy scientists ever conducted with other foreign counterparts since October 1988 when the positive-negative electron collider was built in Beijing.Through the collider, scientists from China and the United States have cooperated and carried out legions of scientific research.Saturday's construction commencement function was attended by more than 100 people, including government officials and foreign diplomats, such as Dr. Robin Staffin, Associate Director of Science in the US Department of Energy.Neutrino Oscillation is an intriguing behavior of a sub-atomic particle called neutrino.And the new facility is being built in the mountain near Daya Nuclear Power Plant, which has four reactors with a combined thermal output of 11.6 million kw in operation, and Ling'ao nuclear power plant is not far away. Both nuke power plants will serve as sources of anti-neutrinos for the experiments when the facility is finished.Workers will build three underground experimental halls which will be connected by long tunnels in the mountain that shields the experiment from unwanted cosmic radiation.Each hall will feature a 10-m deep water-pool within which eight anti-neutrino detectors will be deployed. The water protects the detectors from nearby radiation that interferes with the measurement, and helps identify surviving cosmic radiation.And the first experimental hall is expected to be ready by the end of 2008. Commissioning of the detectors in this hall will take place in 2009.Civil engineering construction is anticipated to last about two years, with installation of the last detector scheduled for 2010.Upon completion of the new facility, more than 190 scientists from six countries and regions including the Chinese mainland, Hong Kong, Taiwan Province, the United States and Russia will come over to do research work, according to Chen Hesheng, Chief of the Institute of High Energy Physics with the Chinese Academy of Sciences (CAS).The facility will have a budget of 250 million yuan (US.25 million). And China will be responsible for infrastructure construction and making of four detectors. And the United States will be responsible for making of the rest of the detectors.Wang Yifang, chief scientist on the experiment, said he was confident that the program would make an important contribution to finding a new breakthrough in China's research efforts in particle physics, starting a new horizon in world's neutrino research, and to improving the overall strength of China in science and technology.

China will undertake nearly 10 percent of an international fusion-research project to be implemented this year.The project is called ITER and wants to demonstrate the scientific and technical feasibility of fusion power - the energy of the sun or hydrogen bomb - for peaceful use."The project aims to find a shortcut to solve our energy shortage," Luo Delong, deputy director of the ITER China Office, said at the Oriental Science and Technology Forum held in Shanghai over the weekend.He said Chinese researchers will be in charge of producing various components of the project and escorting them into Cadarache in the south of France where the ITER's key equipment will be constructed.China will inject about one billion yuan (US7.5 million) into the project, accounting for nearly 10 percent of the overall ITER investment, officials said.Other partners in the project include the European Union, the United States, Japan, India and Russia.According to Zhang Jie, a fusion-power scientist of Jiao Tong University, researchers of universities in Shanghai, including Fudan and Donghua, are conducting fusion-related studies.China will further enhance its education in the area to lift the country's overall research power.The long-term objective of the research is to harness fusion nuclear energy to help meet the future energy needs of mankind, project officials said.The aim of ITER is to show fusion can be used to generate electrical power and do the preparation work to build and operate an electricity-producing plant.The key part of the project is to develop a viable fusion-power reactor.Scientists of ITER will test a number of key technologies, including the heating, control, diagnostic and remote maintenance that will be needed for a real fusion-power station, officials said.Local experts said fusion may produce dozens of times more energy than fission, which now directs most of the world's nuclear-power plants.Fission can only be caused by uranium. However, the resource to trigger fusion can be found in ordinary substances from the sea, they said.According to the Website of ITER, the overall construction cost of ITER is estimated at five billion euros (US.37 billion) over 10 years and another five billion euros are earmarked for the 20-year operation period.The ITER organization owns the ITER device and is responsible for all aspects of the project, such as licensing procedures, hardware procurements and operation.

Thirty-five years ago when Henry Kissinger was the US secretary of state, the rationale behind the detente between Beijing and Washington seemed simple: to overcome ideological barriers and parry common threat.The world has undergone a lot of changes since then. The Cold War is now part of history and the leaderships on both sides belong to another generation. But the 85-year-old US diplomatic policy expert believes cooperation between China and the US remains the key to solving many international issues.The two countries should work together on vital issues such as the denuclearization of the Korean Peninsula, nuclear non-proliferation, climate change and energy, Kissinger told China Daily on Sunday."Progress in the Democratic People's Republic of Korea (DPRK) depends on close cooperation between China and the US because we have learned (it) affects the security and the well-being of our country," Kissinger said.He supports the visit of the New York Philharmonic Orchestra to Pyongyang, which he compares to the Philadelphia Orchestra's tour to China in 1973."I also think we have to continue the Six-Party Talks in order to come up with a solution to the nuclear problem," he said.But will Beijing and Washington keep working together closely, given the uncertainties of the US presidential campaigns? Kissinger shrugs off the worries. "In a political campaign, many things are said but they don't last."We have had seven American presidents since the normalization (of ties between China and the US), and no matter what was said in the campaigns, they all have come back to the theme of the beginning of the relations."Beijing-Washington ties will keep moving forward - not always smoothly but positively - somehow like a long-term stock market curve "but without those big fluctuations", Kissinger said.He is certain that the two sides will keep cooperating on China's core concern, the Taiwan issue, to ensure that there is no showdown in the Taiwan Straits."I think Beijing and Washington will cooperate and really pressure Taipei that if they do not pull back it could look extremely unfavorable," he said. "I believe that we will avoid a crisis in the Taiwan Straits."Kissinger has met with every generation of the leadership since the establishment of the People's Republic of China, and hence is familiar with them. And he believes the present leadership can tackle complicated issues."Each generation has its own characteristics. Deng Xiaoping is an enormous figure for his vision and courage in guiding China on the road to market reforms. But every generation of leaders has made some significant contributions," he said."This generation is educated in universities and has more technical knowledge than the first generation. It has handled very complicated situations with considerable wisdom and skill."Kissinger visited China last week at the invitation of the Chinese People's Institute of Foreign Affairs. He has visited the country more than 50 times, and is impressed by the tremendous progress it has made, enabling it to navigate the changes in the world."I see tremendous vitality in the Chinese people and the people I talked with are also ambitious to study and to do something. I identify China with tremendous capacity to grow, and great opportunities with these people."His last visit to China was in a totally different scenario compared to his first few trips when there was no diplomatic or trade link between Beijing and Washington. More than three decades after his ice-breaking visit, Kissinger remains proud of what he did to "open" China."I consider that the single most important thing I did in government and the one that had the best permanent effect."Rice on vital visitUS Secretary of State Condoleezza Rice will arrive in Beijing today amid the heated presidential campaign in her country and some disturbing developments in the Taiwan Straits.Rice has a very busy schedule in Beijing, holding talks with Foreign Minister Yang Jiechi today. She flies to Japan tomorrow morning on the final stop of her Asia tour.This could be Rice's last visit to Beijing, and offers a chance for high-level policymakers on both sides to address issues of mutual concern, ranging from Taiwan to denuclearization of the Korean Peninsula and from Kosovo declaring independence to Sudan."The annual National People's Congress session will begin soon, while US politics is getting more and more focused on the presidential election. So this could be an important chance for high-level talks," said Yuan Peng, a senior American studies researcher with the China Institute of Contemporary International Relations.Yuan said the Taiwan question is likely to be a key topic during Rice's talks with Chinese leaders because neither side wants to see a conflict across the Straits. The Democratic People's Republic of Korea is another issue important to the two sides. 

The country's fast-developing tourism industry is expected to boost the hotel sector, a senior official has said.About 200,000 new hotels, resorts and guesthouses are likely to be built by 2015, head of China National Tourism Administration (CNTA) Shao Qiwei said on Thursday.Addressing a seminar on domestic and international hotels' groups, he said the new structures will include about 10,000 star-rated hotels. The number of five-star hotels in the country is expected to rise from 361 to 500."The World Tourism Organization has forecast that China will grow into a huge tourism market, and have 100 million each of inbound and outbound visitors and 2.8 billion domestic tourists by 2015," he said.The booming tourism market has created the need for new hotels and other infrastructure facilities, he said.The Shangri-La Hotels and Resorts plan to open five new facilities in the country this year, and at least 13 more in big cities such Beijing, Shanghai and Xi'an in the near future, the general manager of Traders Hotel at China World Trade Center in Beijing, Xin Tao, said.In fact, the group plans to open at least 40 new hotels in the country by 2011."The Olympic Games has brought us unlimited business opportunities and the increase of leisure, as well as business, travel in China will add to the appeal of hotel operators," she said.Investment from home and abroad into hotels will hit 340 billion yuan (.14 billion) between 2006 and 2010, the CNTA has forecast.The hotel sector was one of the first to be opened up in China, with Jianguo Hotel in Beijing being the first foreign-invested hotel to be approved by the State Council in 1979.Since then, 67 hotel brands of 41 international groups have entered the country and are managing 516 hotels at present, according to CNTA statistics.The hotel business has been expanding over the past three decades, and by the end of last year there were more than 14,000 star-rated hotels, 100 times more than in 1978.

The highly anticipated Beijing-Shanghai high-speed railway will begin construction next month, a Ministry of Railways official said.The ministry source, who did not want to be named, confirmed in a phone interview yesterday that preparations are now being made for a ceremony to commence construction of the system.Based on that timeframe, the railway will be completed by 2013. Trains running on the 1,318 km railway will then be able to travel at speeds of up to 350 kph and will cut travel time between the two cities from the current 10 hours to less than five.The project involves one of the largest amounts of investment on railways. Industry sources say it will cost more than 200 billion yuan ( billion), more than the 180 billion yuan needed for the Three Gorges Project.Officials say the project will also employ a set of locally developed high-speed railway technology for the first time.The country is said to have already mastered the technologies needed to lay high-speed rail tracks and trains.The first homegrown train able to reach 300 kph rolled off the production line over the weekend, marking China's entry into "an elite club that includes Japan, France and Germany to become the fourth country capable of making such trains", Wang Yongping, Ministry of Railways spokesman said.Officials added that the railway still relies on foreign companies, such as the Germany-based Siemens, to build its signal network and other systems.China has been upgrading the scale and speed of its railway network in the past decade, and the 11th Five Year Plan period (2006-10) is regarded as a critical period for building high-speed railways that can travel at speeds of 200 kph as part of an extensive transport network.At least eight express passenger railways were being constructed as of last year.Xinhua contributed to the story
