It is also believed that Iranian Foreign Minister Abbas Arakchi was denied a visa.
The main topic of the meeting was compliance with the UN Charter and the strengthening of multilateral cooperation.
Russia's Permanent Representative to the UN, Nebenzia, stated that Alimov, who is responsible for matters related to the United Nations, had been invited by Chinese Foreign Minister Wang Yi. According to him, this is a "flagrant case of disrespect" toward China's presidency of the UN.
During the meeting, he also spoke of the need to "update" the UN Charter amid growing instability and conflict, warning that "the giant ship of global civilization is sailing into dangerous waters."
