Secretary of State John Kerry plans to see Iran’s foreign minister this week, in a meeting that comes amid Iranian complaints that it’s not getting the sanctions relief it deserves under last year’s landmark nuclear deal.

A senior U.S. official says Kerry and Mohammad Javad Zarif will meet in New York on Tuesday. The official was not authorized to discuss Kerry’s plans matter publicly and spoke on condition of anonymity.

The meeting follows complaints from top Iranian leaders that the U.S. is not fulfilling its part of the nuclear agreement, in which Iran curbed its atomic program in exchange for sanctions relief. The U.S. insists it has met its obligations but is considering easing or clarifying financial regulations about legal trade with Iran.
