Speaking at the Asia-Pacific leaders’ summit, US President Obama has said that China, Russia and the US are united over the need to prevent Iran from obtaining nuclear arms.
The talks with his counterparts resulted in an agreement on a major objective.
"All three of us entirely agree on the objective, which is making sure that Iran does not weaponize nuclear power and that we don't trigger a nuclear arms race in region," he said.
He added that the three countries will work closely together to explore available options to exert pressure on Iran and resolve the issue diplomatically.
He however stressed that no options are taboo regarding Iran’s nuclear ambition, indicating that the US will not rule out the use of force to stop Iran acquiring nuclear weapons.
