Hu added that economies in the Asia-Pacific region, which are diverse and highly complementary to one other, have gained valuable experience in working together to meet the challenges.

President Hu also expounded China's views concerning the economic and social development:

-- Support sound development of the multilateral trading regime with stronger confidence;

China is committed to the establishment of a fair, equitable and non-discriminatory multilateral trading regime and has participated in the Doha Round negotiations with a constructive stance, said Hu.

-- Meet the climate challenge through full cooperation;

The Chinese president said the UN Framework Convention on Climate Change (UNFCCC) and its Kyoto Protocol represent the main channel for the international efforts to meet this challenge.

He said developed countries should continue to take the lead in emissions reduction after 2012 in keeping with the principles set out in the UNFCCC and the requirements made in the "Bali Roadmap."

"They should at the same time provide financial support and technology transfer to developing countries to help them enhance capacity in tackling climate change," he noted.

Developing countries, on their part, should also endeavor to meet the climate challenge by implementing sustainable development strategies, he added. "The Copenhagen Conference is an important meeting for the international community to work together against climate change."

"China will participate in the negotiations with a positive and constructive attitude and would like to work with all other parties for positive outcomes at the conference," Hu told leaders of other APEC member economies.

-- Promote regional economic integration with a multi-pronged approach;

"We should promote regional economic integration at different levels, in various scopes and through multiple channels," said the Chinese president.

"We should enhance connectivity in infrastructure and other areas among member economies," he added.

-- And counter non-traditional security threats through coordination and cooperation.

"We should establish a new energy security concept featuring mutually beneficial cooperation, diverse development and common energy security through coordination to stabilize energy prices, improve energy mix, facilitate transfer of energy technologies and reduce energy poverty," said the Chinese president.

"We should step up coordination in the prevention and control of influenza A (H1N1), continue to deepen cooperation in disaster prevention and reduction," he added.

"China is committed to the path of peaceful development and a win-win strategy of opening-up, and will always pursue development that is peaceful, open and cooperative and making unremitting efforts toward a harmonious world of enduring peace and common prosperity," said Hu who also briefed leaders of other APEC member economies the current situation of China's economy.

Addressing the meeting, other APEC leaders pledged to continue to adopt economic stimulus policies to revive world economy, jointly promote balanced, inclusive and sustainable economic growth, support multilateral trading regime, and advance regional economic integration.

The APEC leaders issued "Singapore Declaration" before the conclusion of the two-day APEC Economic Leaders Meeting.
