Washington (CNN) The State Department is set to announce all countries that continue to import Iranian oil will be subject to US sanctions, The Washington Post reported on Sunday.

Secretary of State Mike Pompeo will announce Monday morning that as of May 2, countries importing Iranian crude or condensate will no longer be granted sanctions waivers by the State Department, two department officials told the newspaper's columnist Josh Rogin, who is also a CNN political analyst.

"The goal of the policy is to drive up the costs of Iran's malign behavior and more strongly address the broad range of threats to peace and security their regime presents," a State Department official told the Post.

The announcement will come nearly one year after President Donald Trump announced the US was withdrawing from the Iran nuclear deal

On April 2, Brian Hook, senior policy adviser to Pompeo, said in a State Department briefing that the US is "on the fast track to zeroing out all purchases of Iranian crude." Hook said three of the eight importers who had been granted waivers on the Iran oil sanctions are "now at zero." He said a total of 23 importers were at zero.
