DOHA, Jan. 19 (Xinhua) -- Visiting Chinese Premier Wen Jiabao met here Wednesday with Qatari Emir Sheikh Hamad bin Khalifa al-Thani over bilateral ties.During the meeting, Wen said China-Qatar relations have seen rapid development although diplomatic ties between the two countries are young.Both countries have adhered to the principles of respecting each other and treating each other as equals, the premier noted.The Chinese and Qatari economies are highly complementary, and China is ready to work with Qatar to push bilateral political relations and pragmatic cooperation to higher levels from a strategic perspective, said Wen.Chinese Premier Wen Jiabao (L) meets with Sheikh Hamad bin Khalifa al Thani (R), the emir of Qatar, in Doha, capital of Qatar, Jan. 18, 2012.He said he has deeply felt the Arab people's friendship toward the Chinese people during his ongoing Gulf tour, which had taken him to Saudi Arabia and the United Arab Emirates before he arrived in Doha earlier Wednesday.The development of the China-Arab relations has a solid political foundation and enjoys extensive public support, Wen said, adding that both sides hope to intensify pragmatic cooperation so as to promote their socioeconomic development and bring tangible benefits to their peoples.The Chinese premier said he is confident in the future of the China-Arab relations.Noting that profound and complicated changes are taking place across West Asia and North Africa, Wen said China believes that countries in the region can solve their own problems by themselves.China supports the efforts made by Qatar and other Gulf nations in maintaining regional stability, he said, adding that the international community should play a constructive role in this regard and that China is ready to enhance communication and coordination with Qatar.The emir, for his part, said Wen's visit has yielded fruitful results and greatly improved bilateral relations.He said Qatar is committed to pushing forward friendly cooperation with China in various areas, carrying out Qatar-China cooperation projects and stepping up coordination and collaboration with China on regional and world affairs so as to lift the bilateral relations to higher levels.

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

BEIJING, Oct. 24 (Xinhuanet) -- The average global land temperature has increased by around one degree Cetigrade since the mid-1950s, American scientists announced last week after reviewing historical temperature records to date.According to media reports, the scientists of the Berkeley Earth project have studied more than a billion temperature records dating back to the 1800s from 15 sources around the world.And the result is in line with the estimate made by major institutions which keep official records on the global climate, including the Nasa's Goddard Institute for Space Studies in the US and the Met Office's Hadley Centre in Britain.Meanwhile, the scientists established an open database for the climate records so that skeptics on climate change can assess climage change on their own.Nevertheless, the finding of the scientists at the University of California, Berkeley did not convince climate change skeptics, according to a New York Times report.Anthony Watts, one prominent US skeptics, claimed the study's "methodology was flawed". He also noted that the finding was submitted to journal Geophysical Research Letters before being peer-reviewed.Richard Muller, a physicist and head of the project, argued that the decision to circulate the papers before publication was part a long-standing academic tradition of sanity-checking results with colleagues.He added, cited by the Guardian, "We will get much more feedback from making these papers public before publication."

SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.

UNITED NATIONS, Nov. 1 (Xinhua) -- China on Tuesday urged the International Atomic Energy Agency (IAEA) to further strengthen its leading role in enhancing global nuclear safety and promoting relevant international cooperation.Wang Min, Chinese deputy representative to the United Nations, made the remarks at an open meeting of the 66th session of UN General Assembly on the IAEA report.IAEA shoulders important responsibilities in promoting peaceful uses of nuclear energy and preventing nuclear proliferation, Wang said, adding that it needs to further summarize experiences and lessons of the Fukushima nuclear accident, assisting member states to enhance nuclear safety and emergency response capabilities.Wang urged the IAEA to "increase technical assistance to developing countries, improve newcomer's national nuclear infrastructure and promote the safe, secure and sustainable development of nuclear energy."The IAEA was also asked to strengthen nuclear safeguards regime, effectively prevent nuclear proliferation, and maintain an objective and impartial stand on sensitive and hot nuclear issues.China has always adhered to the principle of "safety first", he said. "China has established a rather comprehensive legal and standards system on nuclear safety, put in place an independent and effective supervision and regulatory framework, set up a comprehensive emergency response mechanism, and keep a good safety record in general."China has decided to contribute 200,000 U.S. dollars to the Nuclear Security Fund of the IAEA for the purpose of enhancing nuclear security capability of the Asia-Pacific Region, Wang added.
