BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.

MINSK, Oct. 11 (Xinhua) -- Chinese telecommunications firm Huawei on Tuesday showcased its latest solutions in mobile broadband at an exhibition in Belarus.Focusing on the possibilities of expanding the capacity of mobile operators' networks, the solutions propose to use fourth-generation network standards and introduce elements of intelligent network resources.The exhibition also presented the latest generation of radios, transportation equipment, and terminal solutions."Mobile traffic is constantly increasing, but profit is not growing so fast - about 20 to 30 percent," Xu Zhidong, general director of Bel Huawei Technologies, said during the opening ceremony of the exhibition."We need to provide more services. In addition, the market should be presented by more terminal devices. The decisions, which are displayed at the exposition, will not only increase the volume of Internet traffic, but also increase average profit per subscriber," he added.Lu Guicheng, China's ambassador to Belarus, said Huawei has seen a very successful development, including in the Belarussian market.Huawei, China's largest telecommunications company, which began investing in Belarus in 2003, signed an agreement with the Eastern European nation last month to set up a network technology training center in Belarus for telecommunications technology research and training.It also agreed last month to help more than 300 Belarussian companies with their information technology construction over the next four years.

UNITED NATIONS, Oct. 28 (Xinhua) -- China's progress in meeting a development goal on children's health can serve as an inspiration to other countries working towards the same objective, Dr. Renee Van de Weerdt, chief of maternal, newborn and child health at the UN Children's Fund (UNICEF) told Xinhua in an interview Friday.Van de Weerdt said that "the example of China is very encouraging because it means it can be done, even in a very big country with a very big population."China is on track to meet the fourth Millennium Development Goal (MDG), one of the eight development targets that the international community has pledged to meet by 2015. MDG 4 requires that each country reduce its rate of mortality for children under age five to two-thirds of what it was in 1990.According to Van de Weerdt, most deaths of children under five take place in the first month of life. After the first month, the most prevalent causes of death are pneumonia and diarrhea.ACHIEVING THE GOAL WORLDWIDEThe international community has been doing "relatively well" in working towards achieving MDG 4, Van de Weerdt said.The UN Interagency Group for Child Mortality Estimation (IGME) stated in their 2011 Report on Levels and Trends in Child Mortality that the number of under-five deaths worldwide has dropped from more than 12 million in 1990 to 7.6 million in 2010."We really continue to see progress," Van de Weerdt said. "The number of children that die every year continues to drop so we are really pleased to see that progress. Unfortunately, the progress isn't sufficient to really be able to say that if we continue at this pace we would achieve MDG 4 by 2015."Some regions, according to Van de Weerdt, like Latin America and parts of Asia are making more headway towards the goal than others that are currently lagging behind.

WASHINGTON, Nov. 24 (Xinhua) -- An inexpensive drug that treats Type 2 diabetes has been shown to prevent a number of natural and man-made chemicals from stimulating the growth of breast cancer cells, according to a newly published study by a Michigan State University researcher. The research, led by pediatrics professor James Trosko and colleagues from South Korea's Seoul National University, provides biological evidence for previously reported epidemiological surveys that long-term use of the drug metformin for Type 2 diabetes reduces the risk of diabetes-associated cancers, such as breast cancers.The research appeared online this week in PLoS One.For the study, Trosko and colleagues focused on the concept that cancers originate from adult human stem cells and that there are many natural and man-made chemicals that enhance the growth of breast cancer cells. Using culture dishes, they grew miniature human breast tumors, or mammospheres, that activated a certain stem cell gene. Then the mammospheres were exposed to natural estrogen -- a known growth factor and potential breast tumor promoter -- and man-made chemicals that are known to promote tumors or disrupt the endocrine system.The team found that estrogen and the chemicals caused the mammospheres to increase in numbers and size. However, with metformin added, the numbers and size of the mammospheres were dramatically reduced. While each of the chemicals enhanced growth by different means, metformin seemed to be able to inhibit their stimulated growth in all cases."While future studies are needed to understand the exact mechanism by which metformin works to reduce the growth of breast cancers, this study reveals the need to determine if the drug might be used as a preventive drug and for individuals who have no indication of any existing cancers," Trosko said.

BEIJING, Jan. 1 (Xinhua) -- State Grid Corporation of China (SGCC), the country's largest power supplier, said Sunday it has put to trial operation a cross-border electricity transmission project in northeastern Heilongjiang province to supply Chinese with Russia's electric power exports.The electric power SGCC purchased from Russia began reaching Chinese customers late Saturday night after the completion of the direct-current back-to-back networking substation, or called "the trans-Amur project" by Russians, SGCC said in a statement on its website.The trial operation will last 168 hours, SGCC said in the statement.With a transmission capacity of 750 mega-watts, the electricity transmission project is China's biggest cross-border power line, according to SGCC."The implementation of the project will gain experience for the expansion of Sino-Russian energy cooperation and help promote the economic development for both countries," SGCC said.The project is also part of the Sino-Russian energy and trade cooperation.Russian Deputy Energy Minister Andrei Shishkin said in June 2011 that the transmission project would increase Russia's power supply to five or six billion kilowatt hours of electricity to China and Russia intended to increase its electricity supply to China in the coming years.Russian companies plan export 60 billion kwh of electricity to China by 2020. Power plants will be built along its border with China to reduce power transmission losses and reduce transportation costs.Also on Sunday, an oil pipeline linking Russia's far east and northeast China witnessed its one year anniversary of operation, as operators announced an accumulated 15 million tonnes of oil had been transported into China in 2011.
