Iran's Foreign Minister Javad Zarif is heading to Beijing, Moscow and Brussels over the next few days in a bid to save the Iran nuclear deal after the US withdrawal. Zarif's mission will be to safeguard the deal's economic benefits in exchange for Iran's continued compliance. But the U.S. is vowing to isolate any company both domestic and foreign that continues to deal with Iran. CGTN's Nathan King has the latest from the White House.  

Starting Saturday, Iran's foreign minister is set to visit China, Russia and the headquarters of the European Union in Brussels. His talks could mean the difference between the Iran nuclear deal continuing or totally collapsing. Meanwhile, Europe continues to react angrily to the U.S. threat to impose sanctions on any businesses that continue to deal with Iran. France's finance minister accused the U.S. of interfering in national sovereignty.

BRUNO LE MAIRE FRENCH FINANCE MINISTER "I think there is a true realization. A realization among all European states that we cannot keep going in the direction we are headed today whereby we submit, we submit to American decisions. Do we want to submit or do we prefer becoming independent and sovereign?" 

On the streets of Tehran more protests against Washington's unilateral withdrawal from the 2015 accord.

Iran was in full compliance with the agreement which saw over 95% of its nuclear fuel shipped out of the country and thousands of centrifuges shut down. But the Trump administration says the Iran deal did not fulfill its promise of bringing Iran back into the international community.

National Security Adviser John Bolton wrote this week: "Rather than focusing on behaving responsibly, Tehran has poured billions of dollars into military adventures abroad, spreading an arc of death and destruction across the Middle East from Yemen to Syria."

But, every other signatory says the agreement is working and was only meant to cover Iran's nuclear activities-nothing else.

The Iranian foreign minister's shuttle diplomacy is aimed at convincing Europe, Russia and China to stay invested in Iran-despite U.S. pressure.
