Zarif made the remarks in a meeting with representatives of Iran's Chamber of Commerce, Industries, Mines and Agriculture on Sunday, several weeks after the US move to withdraw from the nuclear agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA). US President Donald Trump has also vowed to re-impose nuclear sanctions on Tehran.

He added that the US is the dominant economic power in the world and its strategic objective is to force Iran to exit the JCPOA.

"Of course, this does not mean that we will never walk away from the JCPOA under any circumstances, but we know the opposite side's goal," the Iranian foreign minister said.
