China's President Hu Jintao is to elaborate the country's stance on various current issues, ranging from climate change and nuclear disarmament to economic recovery and trade protectionism, to United Nations and G20 summits next week.

"Hu will call for stronger international efforts on climate change and introduce new measures that China is taking," China's Vice Foreign Minister He Yafei said at a press briefing Tuesday.

The briefing outlined Hu's attendance at the summits in the United States next week.

Invited by UN Secretary General Ban Ki-moon, Hu will address the opening session of a UN climate change summit on Sept. 22.

"He will fully elaborate China's stance and proposals on climate change and what China is doing about it," He said.

He said the UN summit was expected to "inject a political impetus" into the Copenhagen conference in December, which will attempt to formulate a post-Kyoto deal on climate change.

He reaffirmed "common but differentiated principles" and called for developed nations to share technology and funding with developing ones.

"We hope the summit will send a positive signal," He said, emphasizing joint efforts to make the Copenhagen conference a success.

Hu will also deliver a speech at the 64th annual general debate of the UN General Assembly, outlining China's ideas about how to safeguard world peace, boost common development, promote mutual benefit and seek harmonious co-existence.

Talking about Hu's attendance at the G20 financial summit in Pittsburgh, He said the summit would held against a "special background."

He said China expects the summit to achieve positive results in macro-economic policy coordination, reform of international financial organization, development and measures against protectionism.

He said China hoped the summit would agree on further strengthening coordination on macro-economic policy so as to promote recovery of the world's economy.

He called for the summit to actively advance reform of governance of international financial institutions by giving a greater say and representation to developing countries and emerging economies.

The summit should promote common development and pay attention to development of developing countries, especially the least developed ones, He said.

He proposed the summit adopt a clear position on opposing trade protectionism by pushing forward the Doha Round talks to achieve comprehensive, balanced results at the earliest possible date.

He said the previous two summits had achieved important results and reached a great deal of consensus.

"Through the previous two summits, people realized that G20 leaders' gathering and discussion of major international economic and financial issues have become an effective platform for the international community to seek a collaborative response to financial crisis and reform, and strengthen global economic governance," He said.

At the invitation of President Barack Obama, President Hu will attend the nuclear non-proliferation and disarmament summit of the Security Council to be held at UN headquarters on Sept. 24.

The president will elaborate China's ideas of realizing common security through a win-win approach to mutual benefits. Hu will put forward China's propositions on nuclear non-proliferation and disarmament, peaceful use of nuclear power, nuclear security and other issues concerning the international community.

"The summit, which is being specially convened to discuss nuclear non-proliferation and disarmament, will be the first of its kind in the history of the UN Security Council," He said.

The summit is of great significance, He said, expressing the wish it will further gauge the consensus of the international community and explore effective ways in the process of advancing nuclear non-proliferation, disarmament and peaceful use of nuclear power.

He said the summit will discuss major issues concerning peace and security, including arms control and nuclear disarmament, the international mechanism of nuclear non-proliferation, prevention of illegal nuclear material trafficking and security of nuclear materials.

He said the international community held a broad consensus on nuclear non-proliferation and has expanded cooperation in this area.

But He said implied in the issue were many complicated and uncertain factors.

In the area of nuclear arms control and disarmament, He said the international community unanimously wanted to advance the process of nuclear disarmament and realize the peaceful goal of non-existence of nuclear weapons.

Regarding outstanding energy problems around the globe and greater priority of nuclear power by various countries, the international community faced the common issue of strengthening cooperation in effective and peaceful use of nuclear power, He said.

Security of nuclear materials and combating nuclear terrorism were among the issues concerning all countries.

The Security Council meeting would listen to opinions of all its members, especially the developing countries.

"We think this meeting should both reflect the authoritative role of the Security Council in maintaining international security and support other international and multilateral organizations within the UN framework to carry out active and effective work," He said.

President Hu will also meet leaders of other countries on the sidelines of the UN and G20 summits.
