Iran says it will pressure the United States to ease its access to non-American banks as part of last year's landmark nuclear deal.

Mohammad Javad Zarif said Saturday that under the deal, "the other parties, particularly the United States, are required to implement commitments to remove barriers in banking cooperation."

He spoke during a joint press conference with visiting EU foreign policy chief Federica Mogherini.

Iran says the U.S. and the European Union have locked it out of the international financial system despite the deal.

The U.S. and other world powers lifted all nuclear-related sanctions in exchange for Iran curbing its nuclear program under the deal reached last summer. However, Washington has kept other sanctions in place over Iran's alleged support for terrorism and its ballistic missile program.
