UNITED NATIONS, Jan. 19 (Xinhua) -- China's Permanent Representative to the UN Li Baodong said here Thursday that caution should be called for in metering out sanctions in international affairs.Li made the remarks when addressing a Security Council open debate on the question of justice and rule of law."We are in favor of improving the UN sanction regime on the basis of extensive consultations so as to improve its credibility, procedures and establishing effective monitoring mechanisms and to establish strict criteria, define timelines, " Li said."Sanctions should be only carried out on basis of facts and evidence. Double standards must be avoided. Impacts against civilian lives and social economic development must be minimized," the ambassador said.Stressing that the UN chart and the fundamental principles of international law as established in it should be upheld, Li said rule of law in international relations should be strengthened.The Charter as well as principles of international law established in it constitute the call of rule of law in international relations and represents the bedrock for developing rule of law in international relations, he said."In the conduct of international relations and international affairs, adherence to the Charter and other fundamental principles of international law, such as respect for national sovereignty, non-interference in internal affairs, fulfillment in international obligation in real earnest is the essence of promotion of international rule of law," said Li.According to the Charter, UN Security Council resolutions constitute the integral part of international rule of law. Promotion of international rule of law requires strict implementation of the Security Council resolutions by member states, he added.

VIENNA, Nov. 25 (Xinhua) -- China is to further help the least developed countries (LDCs) in their development effort through zero-tariff treatment and other measures, Yu Jianhua, China's Assistant Commerce Minister said here Friday.Addressing a LDCs Ministerial Meeting in Vienna, Yu said China will focus on six concrete measures to advance the implementation of the Programme of Action (IPoA), adopted by the Fourth United Nations Conference on LDCs in Istanbul in May.First, as announced by Chinese president Hu Jintao during the G20 summit in Cannes, China would, in the context of South-South cooperation, give zero-tariff treatment to 97 percent of the tariff items of exports to China from the LDCs that have diplomatic relations with China.Second, tilt foreign aid further to the LDCs.Third, carry out cooperation in livelihood projects in the LDCs, including hospital, school, domestic water use and clear energy.Fourth, strengthen agricultural cooperation with the LDCs, including the increase of food aid, dispatching agricultural and technical experts.Fifth, strengthen personnel education in the LDCs to build capacity for self-development.Sixth, continuously promote the establishment of economic and trade cooperation zone in the LDCs by Chinese companies.Yu said that debt crisis in some countries, turmoil in financial markets, inflation pressure in emerging countries; extreme weather and recurrent natural disasters have brought enormous harm to the economies of the LDCs.In this situation, the global community should stand united to give more supports to the LDCs, he stressed.For a long time, China has actively supported the LDCs, under the framework of the South-South Cooperation, through economic and technical aids, debt reduction and personnel training and increase of imports from these countries, he said.Meanwhile, Yu praised the unique role of the UN Industrial Development Organization (UNIDO) in implementing the IPoA, helping structural transformation in the LDCs and promoting the sustainable development.He also said that the Chinese government would continue to support the UNIDO and help the LDCs develop their economies in an all-round way.

WASHINGTON, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.

YICHANG, Oct. 30 (Xinhua) -- China's Three Gorges Dam on Sunday reached its designed highest mark, the second time for the world's largest water control and hydropower project to run at full capacity.The water level hit 175 meters at 5 p.m. after storing water for nearly two months from the water level of 152 meters, said an official with the China Three Gorges Project Corporation (CTGPC), the developer of the project.A dozen hydropower turbo-generator units started operation on Sunday, generating power capacity of 8.2 million kw, said the official.The dam in central China's Hubei Province completed its first full-capacity test last October.Operating at full capacity should give full play to the dam's functions of generating hydroelectric power, delivering water to the lower reaches to alleviate spring droughts, and containing water from summer flooding, as required by the State Flood Control and Drought Relief Headquarters.The Three Gorges Project was launched in 1993 with a budget equivalent to 22.5 billion U.S. dollars.So far, monitoring shows the dam is operating smoothly.
