China and Iran agreed on Wednesday to uphold the effectiveness of the Joint Comprehensive Plan of Action and the authority of the United Nations Security Council Resolution 2231, and reject any practice to break the agreement.

The pledge was made at a videoconference between State Councilor and Foreign Minister Wang Yi and Iranian Foreign Minister Mohammad Javad Zarif.

The two countries have always understood and supported each other on issues concerning each other's core interests, and jointly safeguard international justice, Wang said.

The state councilor recently wrote to the UN secretary-general and the rotating president of the Security Council to stress that the Joint Comprehensive Plan of Action, endorsed by Security Council Resolution 2231, is an important outcome of multilateral diplomacy and a key element in the international nuclear non-proliferation system, according to the Foreign Ministry.

China would like to work with the international community, including Iran, to uphold multilateralism and the authority of the UN, Wang said.

Wang said that in light of the change in the COVID-19 situation, China is willing to study possible ways to gradually resume personnel exchanges and promote cooperation with Iran.

Some countries have politicized the epidemic and stigmatized other countries, which is detrimental to anti-epidemic efforts and international credibility, and has disturbed international anti-epidemic cooperation, he said.

The epidemic will end, and all unreasonable unilateral and bullying practices will be abandoned by history, he added.

Zarif said Iran welcomes the initiative proposed by China to build the Silk Road of Health, and is willing to participate in relevant cooperation.

Iran opposes relevant countries using the epidemic for purpose of politicization or stigmatization, he said.

He added that the country also opposes the United States' interfere in China's domestic affairs, including Hong Kong affairs.
