European powers are planning on Thursday to reiterate their commitment to the Iran nuclear deal, Reuters reported.

The foreign ministers of Britain, Germany and France, along with Iranian Foreign Minister Mohammad Javad Zarif, are planning to reaffirm their support at a meeting with the European Union’s top diplomat, Federica Mogherini, according to the report.

One diplomat told Reuters the aim is to "send a message to Washington that Iran is complying and that it is better to have the nuclear agreement than to isolate Tehran."

Recertification indicates Iran is living up to its side of the deal to limit its nuclear activities in exchange for sanctions relief by the U.S. and other countries.

Trump refused to make the certification the last time the deadline rolled around, but because it's a requirement of U.S. law, and not the deal itself, that move did not kill the accord.

In the days after Thursday's certification deadline, Trump will also have to decide whether to continue waiving sanctions lifted as part of the deal.
