China supports rational and necessary reform of the United Nations Security Council (UNSC), a foreign ministry spokesman said Tuesday.

China maintains that increasing the representativeness of developing countries at the UNSC should be prioritized, Hong Lei said at a press conference.

China hopes that all parties could act democratically and negotiate patiently to reach a consensus on the UNSC reform-related issues, Hong said.

Hong stressed that negotiations should serve the goal of narrowing differences, maintaining solidarity and bringing mutual benefits.

China is willing to maintain contacts and negotiate with other UN member states including India on the UN and UNSC reform, Hong said.

China values the role India plays in international affairs, and China understands and supports India's willingness to play a bigger role at the UN, Hong added.

Responding to a question about a new nuclear energy pact between India and the United States, the spokesman said China hopes international cooperation could favor regional peace, stability and development, and it should also help maintain the integrity and effectiveness of the international non-proliferation system.

China holds that all countries have rights to peacefully use nuclear power under the precondition of fulfilling nuclear non-proliferation obligations, Hong said.

India and the United States on Monday inked a pact to set up a Global Center for Nuclear Energy Partnership in the northern state of Haryana to promote research and development as well as to strengthen global nuclear security.
