Obama committed to 'diplomacy' on Iran

US President Barack Obama says Washington is committed to a "diplomatic solution" to Iran's standoff with the West over its nuclear case, Press TV reported.

"We remain committed to a diplomatic solution. But the Iranian government must understand that the path of defiance will only bring more pressure and more isolation," Obama said in a joint news conference with British Prime Minister David Cameron in Washington on Tuesday.

"The Iranian government must fulfill its international obligations," Obama stated, adding that "the new sanctions imposed by the United Nations Security Council, the United States and other countries are putting unprecedented pressure on the Iranian government."

"I thanked David [Cameron] for Great Britain's efforts to ensure strong European Union sanctions in the coming days," the US president said.

Cameron, for his part, called on Tehran to resume talks with the "international community" on its nuclear program.

"It is not too late," Cameron added. "American and Britain, with our partners, stand ready to negotiate and to do so in good faith. But in the absence of a willing partner, we will implement with vigor the sanctions package agreed by the United Nations Security Council."

The UN Security Council imposed a fourth round of sanctions on Iran on June 9 over its disputed nuclear program, while the United States and the European Union have imposed additional sanctions of their own.
