The US Secretary of State John Kerry said: “Obviously Japan and South Korea, particularly, are deeply concerned because of the neighborhood.
“But I think it’s fair to say China, Russia and the United States, everybody shares concerns about it.
“At the appropriate moment today I’m confident President Obama will address [this] and we will certainly be discussing this in the context of the United Nations, for sure.”
Mr Kerry made his comment during a meeting with Russian Foreign Minister Sergei Lavrov in Geneva, Switzerland, to discuss the crisis in Syria.
Mr Lavrov said: “I’m very much concerned and the resolution of the Security Council must be implemented and we must send this message very strongly.”
