Chinese Foreign Minister Wang Yi on Tuesday called for renewed commitment to the United Nations Charter and warned against unilateral actions and "double standards", amid growing geopolitical tensions and challenges to multilateralism.

Wang, also a member of the Political Bureau of the Communist Party of China Central Committee, made the remarks while presiding over a Security Council high-level meeting on upholding the purposes and principles of the UN Charter and strengthening the UN-centered international system.

Wang said the current international situation is undergoing the most complex and profound changes seen since the Second World War, stressing that the challenges confronting the world today test the international community's conviction to safeguard peace, its resolve to uphold justice, and its courage to pursue reform and innovation.

"We must unite and take action to uphold, revitalize and strengthen the United Nations," he said.
