UNITED NATIONS - A Chinese envoy to the UN on Tuesday called on the international community to adhere to the UN charter and solve problems through peaceful means in addressing security threats.

Liu Jieyi, China's permanent representative to the UN, made the call at a meeting of UN General Assembly on the Secretary-General' s report on the work of the organization.

"The United Nations, in particular the Security Council as the core of the collective security mechanism, is duty-bound to maintain the international peace and security," Liu said.

On the issue of Iraq, Liu said China supports Iraq in safeguarding its national sovereignty, independence and territorial integrity, and calls for greater humanitarian aid to Iraq so as to help the Iraqi people.

As for the Syria crisis, he said all parties in Syria must achieve ceasefire as soon as possible and restart talks to work out a solution that accommodates the interests of all parties.

"China firmly opposes all forms of terrorism," he said. "We support the international community to implement Security Council resolutions and on the basis of respecting the purposes and principles of the UN Charter and basic norms governing international relations, coordinate the efforts to address threats of terrorist forces."

Highlighting the significance of the post-2015 development agenda, Liu said it should achieve three goals of improving people 's well-being, advancing inclusiveness and focusing on implementation of its targets.

"The international community must demonstrate the spirit of mutual interests, win-win and cooperation, jointly develop a fair, inclusive and sustainable post-2015 development agenda," he said.

Liu also commended the results of the UN Climate Change Summit held last month, saying it has injected "fresh political momentum" into international cooperation in climate change.

"We hope the international community, on the basis of common but differentiated responsibilities, fairness and respect capabilities, will complete by 2015 the negotiations on a post- 2020 new regime to address climate change, and make more just, rational and effective arrangements for international cooperation on climate change," he said.
