Chinese President Hu Jintao will attend the Nuclear Security Summit on April 12 and 13 in Washington, Foreign Ministry spokesman Qin Gang said Thursday.

"China attaches importance to nuclear security, opposes nuclear proliferation and nuclear terrorism, and supports international cooperation," Qin said at a regular press briefing in Beijing.

Leaders and representatives from more than 40 countries and some regional and international organizations, such as the European Union and the International Atomic Energy Agency, will take part in the conference.

"We hope the summit will achieve a consensus by all countries on nuclear security and yield positive results," Qin said.

After the meeting, Hu will pay a state visit to Brazil and attend the second summit of the BRIC nations -- Brazil, Russia, India and China -- in Brasilia from April 14 to 17, Qin said.

Hu will also pay a state visit to Venezuela on April 17 and 18, and make a working visit to Chile on April 18, Qin said.

During Hu's meeting with leaders of Brazil, Russia and India, they will discuss the global economy and financial situation, issues related to G20, reform of the international financial system, climate change and cooperation among the four countries, he said.

China hoped the summit participants could discuss global issues in spirit of mutual benefit, so as to facilitate the recovery of world economy, safeguard the four nations' common interests and advance cooperation, Qin said.

China always adopted a "positive, pragmatic, open and transparent" attitude towards cooperation with other BRIC nations, Qin said.

Closer cooperation and exchanges between the four nations would be conducive to increasing the influence of emerging and developing countries, and promoting the development of multilateralism, he said.

Qin said the Latin American tour was aimed at seeking common development and deepening friendship as well as mutual trust.

The visit will be of great significance to cementing friendship between China and the three countries and pushing forward the China-Latin America relationship.

China's relations with Latin American nations were enjoying a rapid and comprehensive momentum of development, and "China believes the upcoming visit will be a success," Qin said.
