Iran → accord → cent
Iran's UN mission thanked China and Russia for vetoing the resolution, saying on social media that the countries “prevented yet another cynical attempt by the United States and its allies to abuse the Security Council for their political purposes.”

U.S. Deputy Ambassador to the UN Jennifer Locetta said the United States wasn't surprised by the vetoes because the experts “would have shined the light" on prohibited cooperation between Iran and its partners.

Locetta → lose → measures
Russian UN Ambassador Vassily Nebenzia reiterated Moscow's claim that the “snapback” of sanctions against Iran was illegal, and therefore the resolution to extend the mandate of the panel of experts “was deeply flawed and did not have any legal basis.
uncertain
resolution → reiterate → basis
Russia and China had strongly urged the U.S. and its allies not to put the resolution to a vote, which would only increase tensions in the council, Nebenzia said, but Washington “decided to opt for confrontation.”
asserted
Washington → urge → confrontation
