WASHINGTON (AP) — The Trump administration on Wednesday granted important exemptions to new sanctions on Iran's Revolutionary Guard, watering down the effects of the measures while also eliminating an aspect that would have complicated U.S. foreign policy efforts.

Foreign governments and businesses that have dealings with the Revolutionary Guard and its affiliates will not be subject to a ban on U.S. travel under waivers outlined by Secretary of State Mike Pompeo in two notices published in the Federal Register.

That weakens the effect of the measures and will frustrate members of Congress backing tough measures against Iran who are already concerned that the Trump administration won't fully enforce sanctions on Iranian oil. But it lifts the threat that those who work with the U.S. in Iraq and Lebanon, where the Guard's many subsidiaries are active, will face the full weight of American penalties.

The waivers leave intact sanctions that apply directly to Iran's Revolutionary Guard and its proxies, which are the first agencies of a foreign government that have ever been designated a foreign terrorist organization by the United States. The designation, which took effect April 15 , is part of a broader administration effort to increase pressure on Tehran.

Iranian Foreign Minister Mohammad Javad Zarif, speaking Wednesday in New York, said the administration is creating dangerous conditions with its campaign against Tehran. "Iranians are allergic to pressure," he said, adding that he believes the conflict can be resolved diplomatically.

Under U.S. immigration law, foreigners found to have provided designated foreign terrorist organizations with "material support" can be banned from the U.S.

When it was announced earlier this month, the designation raised fears that U.S. diplomats and troops might have to end contacts with officials in countries that have ties with Iran or elements of the Guard, a paramilitary organization formed in the wake of Iran's 1979 Islamic Revolution to defend its clerically overseen government.

Lebanon, where Iran and the Guard are active in their support of the militant Hezbollah movement, and Iraq, where they back Shiite militias and have close ties to the government, are two such countries where the U.S. is heavily engaged on the military and diplomatic fronts.

Pompeo said in the notices that he decided to waive the travel bans in U.S. foreign policy and national security interests.

In one notice, he said the sanctions "shall not apply to any ministry, department, agency, division, or other group or subgroup within any foreign government" unless that entity is covered by existing U.S. sanctions.

In the second notice, he said the sanctions won't apply "to any business, organization, or group, whether public or private, solely based on its provision of material support to any foreign government sub-entity that has been designated as a foreign terrorist organization."
