Russia and China have started making the case at the United Nations against Washington’s claim that it can trigger a return of all sanctions on Iran at the Security Council, with Moscow invoking a 50-year-old international legal opinion to argue against the move. Russian Foreign Minister Sergey Lavrov and the Chinese government’s top diplomat, Wang Yi, both wrote to the 15-member council and U.N. chief Antonio Guterres as the United States threatens to spark a so-called sanctions snapback under the Iran nuclear deal, even though Washington quit the accord in 2018.
