JIUQUAN/BEIJING, Nov. 1 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced early Tuesday that the launch of Shenzhou-8 unmanned spacecraft was successful.The spacecraft was sent into the designated orbit after the blastoff at 5:58 a.m. from the Jiuquan Satellite Launch Center in northwest Gobi desert, carried by an upgraded Long March-2F rocket.It is heading for rendezvous with Tiangong-1, or "the Heavenly Palace" that was put into space on Sept. 29 for the country's first space docking.The move, if successful, will pave the way for China to operate a permanent space station around 2020 and make the nation the world's third to do so.The combined photo taken on Nov. 1, 2011 shows the blast-off of a modified model of the Long March CZ-2F rocket carrying the unmanned spacecraft Shenzhou-8 at the Jiuquan Satellite Launch Center in northwest China's Gansu Province. Commander-in-chief of China's manned space program Chang Wanquan announced that the launch of the spacecraft was successful.Chinese Vice Premier Zhang Dejiang viewed the launch at the Jiuquan center. The launch was also observed on site by senior officials from the European Space Agency and the German Aerospace Center.The docking is scheduled to occur within two days after the launch of Shenzhou-8 and at a height of 343 km above the Earth's surface. It will return to the Earth after two docking tryouts.Chinese and German scientists will conduct 17 life science space experiments on the Chinese spacecraft Shenzhou-8, Wu Ping, spokeswoman for China's manned space program, said Monday.To ensure the success of the mission, Chinese space engineers have made "considerable modifications" on Shenzhou-8 to previous versions of the spacecraft.Shenzhou-8, with a length of nine meters and a maximum diameter of 2.8 meters, has a liftoff weight of 8.082 tonnes."More than half of the 600 or so sets of equipment have been modified, while newly designed devices account for about 15 percent of the total," Wu said.The modifications were mainly aimed at arming the spacecraft with automatic and manual rendezvous and docking capacities, and enhancing the vehicle's performance, safety and reliability, Wu said."After the improvements, the spacecraft will be able to connect with the target spacecraft Tiangong-1 for 180 days," Wu said.The unmanned spacecraft is also equipped with devices for recording real images and mechanical parameters during its flight, to test the space docking before a manned attempt.Once China has mastered the technologies of rendezvous and docking, it will be equipped with the basic technologies and capacity required for building a space station, said Zhou Jianping, chief designer of China's manned space program.Tuesday's mission will be followed by launches of spaceships Shenzhou-9 and -10 in 2012, which are also expected to dock with Tiangong-1. "At least one mission of the two will be manned," Wu said.The crew members, including probably two female astronauts, have already been selected for the possible manual space docking mission in 2012 and are being trained for manual docking skills.The space docking tests and experiments will provide crucial experience of China's construction of a 60-tonne permanent manned space station around 2020 when Chinese astronauts are expected to operate more research projects in space."It will make it possible for China to carry out space exploration of a larger scale," Zhou said.

SUVA, Dec. 18 (Xinhua) -- There are 60 typhoid cases in Nanoko, with 29 already hospitalized, according to Fiji's Health Ministry.Senior Health Inspector Paula Laqere said Sunday that the increas means that people are not practicing proper hygiene standards. Laqere said most of the communities in Fiji have a really low level of good hygiene practices.The other problem is that some communities in Fiji have very poor sources of clean and safe water and this is what Fijian guests need to be cautious of."Typhoid is basically spread through contaminated water and our hygiene practices. It's an indicator that the sanitation level of any community is really low."A 30 day public health emergency is in place for the village, effective from Dec. 12 to Jan. 12.Recently, Fiji recorded rates of high typhoid fever in the world, said WHO South Pacific Communicable Disease Surveillance and Response Team leader doctor Jacob Kool.Kool said typhoid fever was difficult to diagnose and could be fatal in 10-20 percent of untreated patients.Recent studies showed that infants are commonly affected and are extremely vulnerable to the disease. Outbreaks occur regularly in areas with poor hygiene and sanitation including urban slums, he said.Kool said the only reliable symptom was prolonged fever and blood and stool culture are still the best available diagnostic tests but have a high rate of false negative results. He said therefore suspected typhoid cases should be treated regardless of the result of lab tests and ciprofloxacin was the recommended therapy for all age groups.Last year AusAID, WHO and UNICEF launched a typhoid fever vaccination campaign in Fiji.

BEIJING, Oct. 29 (Xinhua) -- Chinese Premier Wen Jiabao and Chairman of the Central Military Commission Hu Jintao Saturday issued an order to publicize the Regulations on Resettlement of Ex-Servicemen, which will take effect from Nov. 1.Formulated with an aim to protect the legitimate rights and interests of ex-servicemen, the 53-article document highlights a series of initiatives designed for the appropriate placement of veterans.State organs, social groups, enterprises and public institutions should give preferential treatment to ex-servicemen while recruiting staff members or contract workers, according to the regulations.The regulations provide that demobilized soldiers who register for a civil servant examination or apply for a position in government institutions will be given preference.Those companies or organizations which recruit retired soldiers will enjoy favorable policies prescribed by current laws and regulations.

CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao on Thursday urged the world's major economies to work together to promote growth and financial stability."It is imperative that we stand on a higher plane, transcend differences on specific issues, move beyond short-term considerations, and jointly seek ways to overcome the crisis and sustain development," Hu told the Group of 20 (G20) summit here."At this critical moment, the G20 must work to address the key problems, boost market confidence, defuse risks and meet challenges and promote global economic growth and financial stability," said Hu.As the premier forum for international economic cooperation, the G20 must continue to demonstrate the spirit of standing together in times of adversity and pursuing win-win cooperation, he said.The Chinese president said "the current world economic situation deserves our high attention," cautioning the global recovery is fraught with instability and uncertainty and faces growing risks and challenges.Some major economies are experiencing economic slowdown and some countries are facing acute sovereign debt problems, said Hu.He also cited volatility in the international financial markets, and high inflationary pressure in emerging markets.Hu put forward a five-point proposal on what G20 nations need to do to tide over the crisis.First, the countries should ensure growth while paying attention to balance. Given the serious risks facing the global economy and continued market volatility, ensuring growth and promoting stability should be the top priority, he said."We should introduce new and strong measures to ensure that fiscal and monetary policies are fully implemented and that funding is channeled into the real economy to boost production and employment."Second, the G20 nations should strengthen unity and send a strong signal to the world as there is widespread panic and acute lack of confidence in the markets, said Hu.He urged G20 members to strengthen consultation and coordination, tackle sovereign debt risks, regulate cross-border capital flow, put the fluctuation of commodity prices under control, mitigate global inflationary pressure and make sure that the economic policies pursued by various countries do not offset each other.Third, global economic governance should be improved through reform, Hu said.The international financial crisis has highlighted the deficiencies in the global economic governance system, said Hu."Major efforts should be made to reform and improve the international monetary system, international trading system and commodity pricing mechanism," said the Chinese president.

BEIJING, Oct. 10 (Xinhua) -- The State Council, or China's cabinet, announced on Monday it will tax all resource products starting Nov. 1, extending the resource tax on domestic sales of crude oil and natural gas from some regions to the entire country.The list of taxable resources widened from crude oil and natural gas to coal, rare earth, salt and metal from Nov. 1, according to the country's revised resource tax regulations.The expansion of the resource tax is part of China's efforts to encourage energy conservancy and limit environmental damage.Sales of crude oil and natural gas nationwide will be taxed at a rate between five and 10 percent of their sales value, according to the revised regulations.The regulations impose a sales tax ranging from eight (1.25 U.S. dollars) to 20 yuan per metric ton on coking coal and from 0.40 to 60 yuan per metric ton on rare earth ore.Taxes on other types of coal stood unchanged at 0.30 to five yuan per metric ton.The tax rate for other non-ferrous metals is set between 0.4 to 30 yuan per metric ton. Ferrous metals will be taxed at two to 30 yuan per metric ton.Taxes on precious non-metallic ore will be between 0.5 to 20 yuan per kg or per carat, while taxes on cheap non-metallic ore are set between 0.5to 20 yuan per metric or per cubic meter.China's current resource tax is levied based on production volume instead of sales value, thus preventing the government from benefiting from energy and commodity price increases.Nonetheless, energy giants and mining companies such as PetroChina and Sinopec have enjoyed large profit margins on the sale of resources under the current tax scheme.A resource tax on oil and natural gas was introduced at a rate of five percent in northwest China's Xinjiang Uygur Autonomous Region on June 1, 2010 before being extended to 11 other provinces in December last year.
