Chinese Premier Wen Jiabao 's upcoming UN visit shows China's full support to the world body as well as the country's firm commitment to tackle global threats and challenges, said Chinese UN ambassador Wednesday.

"This has been Premier Wen's second visit to the United Nations since 2008 and the third consecutive year that top Chinese leaders attend UN conferences," Li Baodong, permanent representative of Chinese mission to the UN, told reporters at the residence of the mission.

Calling the upcoming visit "an all-around, multi-level diplomatic event," Li said it fully embodies the great importance China has attached to the multi-lateral diplomacy and its firm support to the United Nations.

Besides, the visit will help to build the confidence of the international community to address the unexpected global threats including the issues of traditional and non-traditional security, imbalance on development and the not-yet-stable recovery situation of world economy, Li said.

"Premier Wen will help promote all sides to show political will and firm resolution, jointly gasping chances and meeting challenges, in a bid to build a world of lasting peace and common prosperity," the ambassador said.

Wen's UN trip, slated for Sept. 21 to 23, includes a UN summit on the Millennium Development Goals (MDG) and the general debate of the 65th session of the UN General Assembly.

During his whirlwind stay in New York, Wen would also meet with U.S. President Barack Obama, UN Secretary-General Ban Ki-moon, and attend a meeting of leaders from the UN Security Council member states, a discussion panel on the MDG and HIV/AIDS.

Li said Wen's visit will also help to enhance UN's role on international affairs.

This year marks the 65th anniversary of the founding of the United Nations. Though facing with various new problems and challenges, the United Nations has remained to be the most universal, representative and authoritative inter-governmental organization; the UN Charter has remained to be the foundation of international law and order and the expectations of the international community of the UN has not changed, Li said.

"Premier Wen's visit will further promote UN's core role in the process of implementing multilateralism and make the world body become an envoy of safeguarding world peace as well as a drive to boost common prosperity," Li said.
