US President Barack Obama has pushed for a “significant regime of sanctions” against Iran unless it accepts international proposals aimed at curbing its nuclear ambitions.
Stepping up the pressure on Iran’s leaders at an impromptu appearance in the White House briefing room, Mr Obama said the United States and five other world powers were “moving along fairly quickly” to tighten the screws on Teheran.
He indicated that his administration had made headway in persuading Russia to overcome its traditional resistance to imposing new sanctions on Iran, even if he was uncertain about whether China would join the other powers.
China now appears to be the sole holdout on sanctions among the five veto-wielding members of the UN Security Council — the other four are the United States, Russia, Britain and France.
