Marco Rubio said the new memorandum differs fundamentally from the JCPOA. He claimed the JCPOA was a real agreement with specific obligations and a defined framework.

According to Rubio, the new text is effectively nothing more than a signed piece of paper and merely says the parties will talk again about continuing the talks.

His remarks came as no further details about the nature or content of this memorandum have been specified in the published text.
