The US State Department announced Monday that it would reimpose sanctions upon Iran previously lifted by the Obama administration’s nuclear deal (Joint Comprehensive Plan of Action, or JCPOA).

“Starting today, all nuclear cooperation with Iran, except for the limited activities for which waivers are being granted, will be sanctionable,” reads the State Department’s press release. Waivers will not be granted for any civil nuclear projects, i.e. nuclear energy programs.

The US initially announced that it would pull out of the JCPOA on May 8, which drew criticism from Iran; supreme leader Ali Khamenei called the move “a mistake.” After Monday’s re-imposition of sanctions, President Hassan Rouhani vowed his nation’s defiance of the sanctions.

In July Iran brought a case before the International Court of Justice (ICJ) alleging that the US’s threat to withdraw from the JCPOA violated the 1955 Amity Treaty, a US-Iran agreement that allows for freedom of respective economies without fear of sanction. In October the ICJ ruled that the US must lift its sanctions on “humanitarian” goods including medical supplies and agricultural products.

Impartial International Atomic Energy Agency inspectors have determined that to date, Iran has been keeping its commitment to JCPOA. “There are no credible indications of activities in Iran relevant to the development of a nuclear explosive device after 2009,” says their report.
