Iranian Foreign Minister Mohammad Javad Zarif says Russian officials have told him they will uphold the terms of the Iran nuclear agreement, despite the US pulling out. Zarif is heading from Moscow to Brussels where he'll hold a meeting with European Union officials. He expects to hear a similar message from them. CGTN's Jack Parrock reports from Brussels.

JACK PARROCK BRUSSELS RIA state news agency reports Iranian foreign minister Mohammad Javad Zarif's visit to Moscow has resulted in Russia and Iran saying they're committed to saving the Iran nuclear deal signed back in 2015 which has opened Iran back up to foreign investments.

Last week, U.S. president Donald Trump pulled out of the deal despite the international community insisting Iran has upheld its side of the bargain. President Trump called the Iranian government a "regime of great terror" and insisted the deal didn't tackle the issues of Iran's influence in conflict zones like Syria and Yemen. But here in Brussels, they say those issues should be dealt with outside the deal. While he visits Brussels, Mohammad Javad Zarif will expect a similar show of support for the deal that he saw in Russia and in China before that. The UK, German and French foreign ministers will be in attendance - those countries being signatories to the Iran nuclear deal.

For the EU, supporting the deal is because the Iranian regime is deemed to be fulfilling its promises in backing away from its nuclear program - but it's also for the businesses who've gone in since the deal was struck. Companies like Renault and Total have been investing in Iran but while European politicians will try to persuade them to stay, Donald Trump has threatened sanctions against anyone who doesn't wind down their businesses in Iran. Mohammad Javad Zarif's tour to try and save the deal will ring the right bells with the politicians, but with U.S. sanctions coming back into force, it's going to be much tougher to persuade businesses to stay.
