BEIJING, Jan. 26 (Xinhua) -- The Chinese government Wednesday raised the minimum down payment requirement for the purchase of second home to 60 percent of the property's value from 50 percent, to curb property market speculation.The decision was announced in a statement released after an executive meeting of the State Council, China's cabinet, which was presided over by Premier Wen Jiabao.File photo taken on Nov. 14, 2010 shows a newly built residential community in east China's Shanghai Municipality.

KIGALI, Feb. 8 (Xinhua) -- Li Zhaozhuo, vice chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), will head a high-level delegation to Rwanda this month to boost friendly and cooperative ties between the two countries.According to a statement released by Rwanda's Senate on Tuesday, the three-day visit will begin on Feb. 18 and is to strengthen regular contacts between Rwandan and Chinese parliamentary chambers on a number of issues and review bilateral projects.Chinese Ambassador to Rwanda Shu Zhan has confirmed that the official delegation from China is "planning an outreach visit" to Rwanda.After a meeting with the Chinese envoy to Rwanda on Tuesday, the president of Rwanda's Senate, Vincent Biruta, said his country's legislative chambers would continue to promote friendly ties with the CPPCC and play a "constructive role" in promoting bilateral cooperation.Rwanda have received training assistance from China in the applications of information communication technology (ICT) in parliaments.The Central African nation has a long-standing bilateral relationship with China in a number of socio-economic areas such as infrastructure, energy, education, health, agriculture and communications.

JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.

BEIJING, Feb. 3 (Xinhua) -- Chinese Foreign Ministry said here Thursday that almost all Chinese travellers stranded in Egypt had returned home by planes sent by the government.A total of 1,848 Chinese, including those from Hong Kong, Macao and Taiwan, had been flown back by Thursday afternoon, the ministry said in a statement.The Chinese government has organized eight flights from four Chinese airline companies to Egypt since Jan. 31.The last two planes, belonging to China Eastern Airlines, returned to Beijing from Egypt Thursday, bringing back a total of 431 Chinese citizens, according to the ministry.

WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.
