BEIJING - New Chinese President Xi Jinping on Thursday pledged that his country will deepen cooperation with the United Nations and shoulder due international obligations.

In a telephone conversation with UN Secretary-General Ban Ki-moon, Xi said that China will work with the United Nations to safeguard international justice and promote international cooperation so as to contribute more to peace and development of the world.

China has always been a staunch supporter and an important partner of the United Nations, Xi told Ban. China has actively advocated and pursued multilateralism, upheld the purposes and principles of the UN Charter and safeguarded the authority of the United Nations and respected its roles in world affairs, Xi added.

The United Nations, in particular, has made important contributions to peace and development in Africa. China is willing to step up cooperation and exchanges with the United Nations to boost peace and development in Africa and in the world at large, said Xi.

Ban congratulated Xi on his election as Chinese president. He expressed the belief that the Chinese people would be able to realize the Chinese dream of great rejuvenation of the Chinese nation under Xi's leadership.

The UN chief thanked China for its strong support for the world body and expressed the belief that cooperation between China and the United Nations would be further expanded.

Ban also wished Xi success in his forthcoming visit to Russia and the three African nations of Tanzania, Congo and South Africa. He also expressed the hope that the BRICS summit in South Africa would produce positive results. The United Nations is willing to strengthen cooperation with China in African affairs, he said.

The United Nations highly appreciates China's adherence to the road of peaceful development and expects China to play a greater and more active role in world affairs, said Ban.

Xi said that China's development is inseparable from that of the outside world and that China stick to the path of peaceful development, continue opening-up policies and promote world peace and development.
