The United Nations Security Council will vote first thing July 20 on a resolution carrying out the landmark nuclear deal with Iran, diplomats said.
The vote is scheduled for 9 am New York time.
A draft of the resolution places curbs on Iran's nuclear program but retains an arms embargo and ban on the supply of ballistic missile technology.
Seven previous UN resolutions on Iran would be terminated when the International Atomic Energy Agency verifies that Iran has implemented nuclear restrictions.
The language of the resolution was negotiated as part of the deal agreed July 14 in Vienna between Iran and five veto-wielding Security Council members - the United States, Russia, China, Britain, and France - as well as Germany and the European Union.
A UN ban on the supply of ballistic missile technology to Iran will remain in place for eight years, an arms embargo for five years, and restrictions on nuclear technology for a decade, according to the draft resolution.
