The chancellor of the University of California, Los Angeles, expressed "fundamental disagreements" with Students for Justice in Palestine (SJP), but said.
He made the remark in a meeting with former French Prime Minister Dominique de Villepin at the venue of the Embassy of Iran in France on November 12 and urged European Union to abide by their commitments within the framework of JCPOA.

Under the deal, Iran undertook to put limits on its nuclear program in exchange for the removal of nuclear-related sanctions.
The other members of the deal have stayed on in an attempt to try and make the pact work.
