Secretary of State Mike Pompeo announced Wednesday a policy shift in the long-standing U.S. embargo against Cuba, opening the door for lawsuits against foreign firms operating on properties Cuba seized from Americans after the 1959 revolution.

“Any person or company doing business in Cuba should heed this announcement,” Secretary Pompeo told Reuters Wednesday.

Specifically, the State Department will not waive a provision of the Clinton Administration-era law that codifies the U.S. embargo against Cuba. The provision, known as Title III of the Helms-Burton Act, has been waived by every president since the law was passed in 1996.

President Trump suspended the provision as well until 2019, when Secretary Pompeo announced in January that the administration would approve a waiver for only 45 days instead of the traditional six months, a move later extended by another 30 days and finally another two weeks to May 2.

By not waiving the provision, lawsuits can be brought forward starting on May 2, when the current suspension expires.

The Associated Press reports that there are roughly 6,000 claims the Justice Department has certified as having merit, worth an estimated value of $8 billion.

National Security Advisor John Bolton also announced during a speech Wednesday that travel and remittance restrictions will also be put in place. Travel to Cuba will now be limited to family visits, restricting those deemed as “veiled tourism,” according to the Miami Herald.

The U.S. exported to Cuba roughly 195,000 metric tons of broiler meat in 2018, at a value of approximately $155 million according to USDA data.
