Zarif and British Foreign Secretary Dominic Raab held a telephone conversation on Monday.
In the phone call, the two senior diplomats conferred on bilateral cooperation between Tehran and London within the framework of the Joint Comprehensive Plan of Action (JCPOA).
They also exchanged views on other issues of mutual interest, including the bilateral relations and certain humanitarian issues.
The Iranian administration has repeatedly called on the three European parties to the JCPOA –the UK, France and Germany- to honor their commitments and facilitate Iran’s foreign trade, as stipulated by the agreement.
