The two countries have had warm relations and both took part in a joint naval exercise in 2019 with Russia in the northern Indian Ocean. China and Iran expected to sign 25-year accord, Iranian state media says Trade between Iran and China has been worth some US$20 billion annually in recent years, down from nearly US$52 billion in 2014 because of US sanctions imposed in 2018 after Donald Trump unilaterally pulled the US out of a nuclear deal between Tehran and world powers, saying it needed to be renegotiated. Iran has pulled away from restrictions imposed under the deal under those sanctions to put pressure on the other signatories – Germany, France, Britain, Russia and China – to provide new economic incentives to offset US sanctions.
