China urges parties to uphold ceasefire, advance talks on Iran nuclear issue

China on Friday called for efforts to preserve the ceasefire and prevent further escalation in the Middle East, stressing that dialogue and diplomacy remain the only viable path to resolving the Iran nuclear issue.

Speaking at an open meeting of the UN Security Council on the Iran nuclear issue on Friday, Sun Lei, China's deputy permanent representative to the United Nations, said tensions in the region had eased temporarily after the United States and Iran signed a memorandum of understanding (MoU), but the ceasefire situation has since faced setbacks and prospects for negotiations remain complicated.

"The proper resolution of the Iran nuclear issue bears on whether the Middle East can return to peace and stability, as well as the common interests of the international community," Sun said.

He urged all relevant parties to advance negotiations with a rational and pragmatic approach.

Sun noted that under the MoU, the United States and Iran committed to respecting each other's sovereignty and territorial integrity, permanently halting military activities on all fronts, and establishing a roadmap for negotiations and sanctions relief.

China called on all parties to remove obstacles, refrain from resorting to force or threatening the use of force, and uphold and implement the outcomes of the MoU, Sun said. He also urged efforts to reach a solution that addresses the concerns of all sides, lift sanctions against Iran as soon as possible, and make substantive progress toward a political settlement.

Sun stressed that resolving the Iran nuclear issue requires respecting the legitimate concerns and lawful rights of all parties.

"Iran should continue to uphold its commitment not to develop nuclear weapons, while its legitimate right to the peaceful use of nuclear energy should be respected," he said.

Sun called on the United States to take concrete actions to create conditions for a political solution, adding that the Security Council's immediate priority should be to maintain an objective and impartial stance, provide time and space for diplomatic efforts, and create a favorable environment for negotiations.

He stressed that the UN Security Council should not become a tool for individual countries to advance their political agendas or exert pressure.

Before the meeting began, the Russian representative said that the UN Security Council Resolution 2231, which endorsed the Joint Comprehensive Plan of Action (JCPOA) on Iran's nuclear program, had expired and that the Iran nuclear issue had been removed from the Council's agenda.

Russia requested a procedural vote on whether to proceed with the meeting. Sun later spoke in support of Russia's position.

Sun said China has repeatedly stated that Resolution 2231 expired on October 18, 2025, after which the Security Council terminated its consideration of the Iran nuclear issue and the UN secretary-general should stop submitting related reports.

"The current situation in the Middle East and the Iran nuclear issue are at a critical juncture. The Security Council should play a constructive role in promoting negotiations and easing tensions," Sun said.

He expressed concern that some Security Council members had insisted on holding a meeting under an agenda item that had already been terminated, claiming to support diplomatic efforts.

Such actions, he said, would not only deepen divisions within the Security Council, but also undermine the atmosphere for negotiations and seriously hinder a political resolution of the Iran nuclear issue.

China urged relevant countries to stop political manipulation at the Security Council, implement the termination provisions of Resolution 2231, safeguard the authority of the Council and the credibility of multilateral diplomacy, and create favorable conditions for a political settlement.

China voted against the procedural motion on the meeting agenda.
