RIYADH, Jan. 15 (Xinhua) -- Visiting Chinese Premier Wen Jiabao and Saudi Arabia's King and Prime Minister Abdullah bin Abdul-Aziz agreed on Sunday to make concerted efforts to enhance bilateral relations under a strategic framework.In their meeting, Premier Wen said Saudi Arabia is a major country in the Arab and Islamic world, which plays a significant role in regional and international affairs.He said China respects Saudi Arabia's political system, development mode as well as its culture and traditions, and is grateful for Saudi Arabia's understanding of and support for China regarding the latter's core interests and major concerns.As the world is undergoing profound changes, China is willing to strengthen coordination with Saudi Arabia on major issues, develop an all-around cooperative partnership in the energy sector, expand cooperation in trade, investment, infrastructure, high-tech, finance, security and law enforcement, so as to enrich the contents of the bilateral relations, he added.King Abdullah said that the government and people of Saudi Arabia cherish friendly feelings for China, and that he believes the strengthening of bilateral cooperation will benefit peoples of both countries.The Saudi king proposed setting up a Saudi Arabia-China high level committee to supervise the two countries' cooperation in the political, economic, cultural and security sectors. Premier Wen agreed with this proposal.On the situation in West Asia and North Africa, the visiting Chinese premier said China respect the choice of the peoples in those countries, understand and support their appeal for reforms, and back the role of regional bodies like the Arab League in maintaining stability.For his part, King Abdullah noted it was the objective of Saudi Arabia's foreign policy to maintain regional peace and stability. Saudi Arabia and China enjoy a high level of mutual trust and share similar views on many issues, he said, adding that the Saudi side wishes to step up consultation and coordination with China.Premier Wen has also met with top Saudi leaders, Secretary General of the Organization of Islamic Cooperation Ekmeleddin Ihsanoglu, and Secretary General of the Gulf Cooperation Council Abdullatif al-Zayani.In a joint statement, the two sides hailed Premier Wen's visit to Saudi Arabia as a complete success, which will contribute to their long-term friendly cooperative relations.The statement said both countries were satisfied with the progress made in bilateral cooperation, and pledged to further enhance relations within the framework of strategic relationship, so as to benefit the two peoples and contribute to regional and world peace, stability and development.The two countries agreed in the document to conduct more high-level exchanges of visits, and to expand trade, investment and cooperation in a wide range of areas. The Saudi side also reiterated its adherence to the one-China policy.Wen arrived in Saudi Arabia Saturday evening after an official visit to Nepal.After his stay in Saudi Arabia, the Chinese leader will continue his visit to the United Arab Emirates and Qatar.

BEIJING, Oct. 6 (Xinhua) -- China's first space lab module were in good condition and all tests went on "smoothly" during the past week, according to a statement issued by the country's space project authorities Thursday.The unmanned module, Tiangong-1, or Heavenly Palace-1, blasted off on Sept. 29 from Jiuquan Satellite Launch Center in northwest China's desert area.Tiangong-1 switched to the orbit of 362 kilometers high and had orbited the Earth for 109 times by 6:00 p.m. Thursday, the statement said.Tests on the module's remote control system, video/audio equipments, temperature/humidity sensors, docking facilities and other functions had been conducted successfully, it added.It also revealed that the Jiuquan Launch Center and other units were preparing for the launch of the Shenzhou-8 unmanned spacecraft, which is scheduled to join the Tiangong-1 later this year.Shenzhou-8 and Tiangong-1 are expected to perform China's first space docking at a height of 340 kilometers above the earth's surface.

WASHINGTON, Dec. 22 (Xinhua) -- The journal Science on Thursday chose the HPTN 052 clinical trial, an international HIV prevention trial as the 2011 Breakthrough of the Year.The study found that if HIV-infected heterosexual individuals begin taking anti-retroviral medicines when their immune systems are relatively healthy as opposed to delaying therapy until the disease has advanced, they are 96 percent less likely to transmit the virus to their uninfected partners. Findings from the trial, first announced in May, were published in the New England Journal of Medicine in August.The study was funded by the U.S. National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health."The HPTN 052 study convincingly demonstrated that anti- retroviral medications can not only treat but also prevent the transmission of HIV infection among heterosexual individuals," said NIAID Director Anthony Fauci in a statement. "We are pleased that Science recognized the extraordinary public health significance of these study results."Science's list of nine other ground-breaking scientific achievements from 2011 include:The Hayabusa Mission: After some near-disastrous technical difficulties and a stunningly successful recovery, Japan's Hayabusa spacecraft returned to Earth with dust from the surface of a large, S-type asteroid. This asteroid dust represented the first direct sampling of a planetary body in 35 years, and analysis of the grains confirmed that the most common meteorites found on Earth, known as ordinary chondrules, are born from these much larger, S-type asteroids.Unraveling Human Origins: Studying the genetic code of both ancient and modern human beings, researchers discovered that many humans still carry DNA variants inherited from archaic humans, such as the mysterious Denisovans in Asia and still-unidentified ancestors in Africa. One study this year revealed how archaic humans likely shaped our modern immune systems, and an analysis of Australopithecus sediba fossils in South Africa showed that the ancient hominin possessed both primitive and Homo-like traits.Capturing a Photosynthetic Protein: In vivid detail, researchers in Japan have mapped the structure of the Photosystem II, or PSII, protein that plants use to split water into hydrogen and oxygen atoms. The crystal-clear image shows off the protein's catalytic core and reveals the specific orientation of atoms within. Now, scientists have access to this catalytic structure that is essential for life on Earth -- one that may also hold the key to a powerful source of clean energy.Pristine Gas in Space: Astronomers using the Keck telescope in Hawaii to probe the faraway universe wound up discovering two clouds of hydrogen gas that seem to have maintained their original chemistry for two billion years after the big bang. Other researchers identified a star that is almost completely devoid of metals, just as the universe's earliest stars must have been, but that formed much later. The discoveries show that pockets of matter persisted unscathed amid eons of cosmic violence.

BEIJING, Oct. 18 (Xinhuanet) -- Some seaweeds can kill the reef-building corals around them by emitting anti-coral chemicals, a new study found.The study was published Monday in the online edition of the journal Proceedings of the U.S. National Academy of Sciences (PNAS).The researchers investigated the interactions between eight different species of seaweed and three species of coral growing in the waters nearby the Fiji Islands, and identified a class of anti-coral organic compounds known as terpenes.These chemicals, found on the surfaces of several species of seaweed, can kill the coral by suppressing its photosynthesis.The finding suggests that the living space competition with seaweeds could be a factor of the coral's worldwide decline.Plant-eating fish normally controls seaweed growth on coral reefs, but the populations of these consumers are declining by the overfishing, which eventually resulted in the seaweed's dominant position, according to the researchers.Despite overfishing, pollution and warming oceans are also the contributors to coral's worldwide decline, said Jennifer Smith, a marine ecologist at the University of California, San Diego.

JINAN, Oct. 24 (Xinhua) -- Chinese scientists have made a breakthrough that could lead to more effective treatments for leprosy.A team from Shandong Provincial Institute of Dermatology and Venereology in east China has identified two new risk variants near IL23R and RAB 32 genes that are responsible for the disease, according to a report published online Monday in the scientific journal Nature Genetics.Knowing that the two gene variants influence susceptibility to leprosy could allow doctors to diagnose the disease in sufferers earlier in its outset, as well as to develop new treatments. A genetic database could now be built up to predict those people particularly susceptible to leprosy, said Zhang Furen, the leader of the research team.The study involved more than 10,000 samples being taken from leprosy sufferers and healthy test subjects and analysed.Leprosy is a chronic nerve-killing disease that leads to problems with patients' skin, feet, hands, legs and eyes. More than 200,000 newly-contracted leprosy cases are reported worldwide every year, and China has around one tenth of the world's sufferers.
