Iran has proposed paying its overdue United Nations membership fees with its seven billion dollars frozen at two South Korean banks due to U.S. sanctions.

On the Iranian Foreign Ministry website on Sunday, ministry spokesperson Saeed Khatibzadeh said the country's central bank is in the process of the relevant approval and negotiation.

The spokesperson urged the UN to guarantee the safe transfer of payments, demanding that it stop using U.S. banks as an intermediary due to concerns over Washington's ill intent towards Tehran and possible misuse of funds.

In a recent letter to the presidency of the UN General Assembly, Secretary-General Antonio Guterres demanded that voting rights of ten nations, including Iran, be restricted after they failed to make their payments.

Iran reportedly has the largest amount of overdue fees totaling 16-point-25 million dollars.
