"If we fail to stand together, then the NPT [nuclear Non-Proliferation Treaty) and the Security Council will lose credibility, and international law will give way to the law of the jungle."

"Neither America nor Russia would benefit from a nuclear arms race in East Asia or the Middle East... That is why we should be united in opposing North Korea`s efforts to become a nuclear power, and preventing Iran from acquiring a nuclear weapon."

On a key dispute between Moscow and Washington - U.S. plans for a missile shield in Central Europe - Obama said the plans could be scrapped if Iran abandons its military nuclear and missile programs.

"If the threat from Iran`s nuclear and ballistic missile programs is eliminated, the driving force for missile defense in Europe will be eliminated."
