"Iran and Europe seek to stabilize the situation in the region and strengthen the Joint Comprehensive Plan of Action. It is very important for us that Europe, China and Russia play their important role in preserving the JCPOA, ensuring the interests of Iran," Rouhani said as quoted on his official website.
The statement comes hours after UK Foreign Secretary Dominic Raab said that he would be looking "hard" at what happens next with the Iranian nuclear deal following Tehran's refusal to comply with the JCPOA.
The country announced that it would now start enriching uranium based on its technical needs and in a "peaceful" manner.
The announcement came amid a severe escalation of tensions in the region after the US assassinated Iranian top military commander Qasem Soleimani.
