The cruise industry’s quick growth and move into Cuba may be coming to an abrupt halt.

ABC News reported late on Thursday that U.S. President Donald Trump and the current administration is “poised to roll back another of his predecessor’s signature accomplishments — the re-normalization of U.S. relations with Cuba, according to multiple congressional and advocacy organization sources with direct knowledge of the administration’s intentions.”

ABC said news would follow “sometime” in June.

“The proposed changes would increase regulations that would make it more difficult for corporations to make deals with Cuba and for Americans to continue to travel to the country,” ABC said.

Carnival Cruise Line, Royal Caribbean International, Holland America Line, Norwegian Cruise Line, Regent Seven Seas Cruises and Oceania Cruises all have significant capacity calling in Cuba aimed at the North America consumer.

Meanwhile, Celestyal Cruises and MSC Cruises both have a strong Cuba presence, but have a broader passenger sourcing base.
