The United States lost a bid on Friday to extend a UN arms embargo on Iran as Russian President Vladimir Putin proposed a summit of world leaders to avoid “confrontation” over a U.S. threat to trigger a return of all UN sanctions on Tehran, Reuters reports.

In a UN Security Council vote, Russia and China opposed extending the weapons ban, which is due to expire in October under a 2015 nuclear deal between Iran and world powers. Eleven members abstained, including France, Germany and Britain, while Washington and the Dominican Republic were the only yes votes.

“The Security Council’s failure to act decisively in defense of international peace and security is inexcusable,” U.S. Secretary of State Mike Pompeo said in a statement.

China’s UN Ambassador Zhang Jun said in a statement after the vote that the result “once again shows that unilateralism receives no support and bullying will fail.”

The United States could now follow through on a threat to trigger a return of all UN sanctions on Iran using a provision in the nuclear deal, known as snapback, even though President Donald Trump abandoned the accord in 2018. Diplomats have said the United States could do this as early as next week, but would face a tough, messy battle.
