WASHINGTON, April 13 (Xinhua) -- Chinese President Hu Jintao on Tuesday called for concerted action by all countries to enhance nuclear security while stressing the need to properly address the challenge."The potential threat of nuclear terrorism cannot be neglected and the risk of nuclear material diversion and illicit trafficking is on the rise," Hu said in a speech delivered at the Nuclear Security Summit here.In the speech, Hu put forward five proposals on ways to strengthen nuclear security.First, the Chinese president said, all countries need to honor their commitments and responsibilities by adopting effective measures to secure nuclear materials and facilities.Chinese President Hu Jintao attends the first plenary session of the Nuclear Security Summit at the Washington Convention Center in Washington, April 13, 2010.Second, Hu said, they should consolidate the existing international legal framework on nuclear security, which consists of the Convention on the Physical Protection of Nuclear Material and International Convention for the Suppression of Acts of Nuclear Terrorism.Hu's third proposal is to strengthen international cooperation by sharing experience, exchanging information and cooperating on law enforcement.Fourth, he said, there is a need to help developing countries enhance their nuclear security capacity. Therefore he called for the International Atomic Energy Agency (IAEA) and the developed countries to offer greater assistance to developing countries in that respect.Finally, the president said that all countries should properly handle the relationship between nuclear security and the peaceful use of nuclear energy.

Taipei, April 25 (Xinhua) -- Signing the cross-Strait economic and trade pact, ECFA, will benefit Taiwan, Taiwan leader Ma Ying-jeou said here Sunday in a television debate.Ma debated with the Democratic Progressive Party (DPP) Chairwoman Tsai Ing-wen during a two-hour televised debate over the economic cooperation framework agreement (ECFA), a free trade agreement the Taiwan authority intends to sign with the Chinese mainland.Taiwan urgently needs a trade pact with China to usher in a golden decade of economic boom, Ma said, accusing DPP of exaggerating the adverse effects of ECFA and manipulating public fear.Lee Tung-Hao, a professor with the National Chengchi University, said there are different voices over ECFA because of public misunderstanding of the pact, but the debate will help build consensus.The ECFA, a priority in cross-Strait relations, is aimed at institutionalizing economic cooperation between the mainland and Taiwan and facilitating and regularizing economic and trade exchanges.

BEIJING, May 10 (Xinhua) -- China will conduct consultations with the European Union on the steel fastener trade dispute in line with the rules of the World Trade Organization's disputes settlement system, said an official with the Ministry of Commerce Monday.China's anti-dumping investigation into carbon-steel fastener imports from the EU was based on Chinese regulations and the assessment of the harm to the domestic industry, said the official.The remarks came after the EU filed a complaint Sunday against China at the World Trade Organization over Beijing's decision to impose anti-dumping measures against carbon-steel fastener imports, which included self-tapping screws, bolts and gaskets.Chinese fastener importers were required to pay a deposit to customs based on the margins -- ranging from 16.8 to 24.6 percent -- between the normal value of the products and the alleged dumping price since Dec. 28, 2009.Initial investigations by the Chinese authorities showed the EU had allegedly dumped carbon-steel fasteners on the Chinese market, which caused substantial damage to the local industry.The temporary anti-dumping measures were adopted to safeguard the legitimate rights and interests of the domestic producers, the official said.China started an anti-dumping probe into EU carbon steel fasteners on Dec. 29, 2008, after an application for a probe by the fastener branch of the China General Machine Components Industry Association on behalf of Chinese fastener producers.

And we never received a report of a school attack," said a spokesman with the Beijing Municipal Public Security Bureau Thursday afternoon.The police have launched an investigation into the source of the rumor, said the spokesman.The rumor came after a series of recent school attacks in China's Fujian, Guangdong, Jiangsu and Shandong provinces.

SUZHOU, April 3 (Xinhua) -- China's police chief Meng Jianzhu Saturday called for nationwide coordination to beef up security for the Shanghai World Expo, which runs from May 1 to Oct. 31.Meng, a State Councilor and Minister of Public Security, made the call in a inspection tour to Suzhou city in Shanghai's neighboring province Jiangsu, where he urged police in Shanghai and its adjoining provinces to execute more security efforts.He asked the police in Shanghai, the provinces of Jiangsu and Zhejiang to fully recognize the challenge and complexity of the security work, and to speed up the building of a coordination mechanism among them.Security departments must step up efforts to detect and remove all kinds of security threats, be fully prepared for challenges, and minimize the affect of the security work on people's lives, he said.
