U.S. allows lawsuits against Cuban entities but shields foreign firms for now

WASHINGTON, March 4 (Reuters) - The Trump administration said on Monday it would allow lawsuits by U.S. citizens against dozens of Cuban companies and other entities on Washington's blacklist but will maintain, for now, a ban against suing foreign firms doing business on the communist-ruled island.

The move marked an intensification of U.S. pressure on Cuba and also appeared aimed at punishing Havana over its support for Venezuela’s socialist president, Nicolas Maduro. But it stopped short of the more severe step of targeting foreign investments in Cuba - though it left the door open to doing so in the future.

Lawsuits in U.S. courts against Cuban enterprises, many linked to military and intelligence services, will be permitted beginning on March 19. But Washington will keep in place until at least April 17 a ban on legal action against foreign firms using property confiscated by the Cuban government since the 1959 revolution, the State Department said.

Every U.S. president has suspended on a rotating six-month basis a section of the 1996 Helms-Burton Act that would allow such lawsuits by Cuban-Americans and other U.S. citizens due to opposition from the international community and fears it could create chaos in the U.S. court system with a flood of legal claims.

But President Donald Trump's administration first announced in January a 45-day review of the matter and has now added another 30 days for further study while allowing the act's controversial Title III on private legal actions to be partially activated for the first time.

Cuban Foreign Minister Bruno Rodriguez said he "strongly rejected" the U.S. action against Cuban companies "arbitrarily sanctioned" by the Trump administration. The 30-day waiver for other cases, he said in a message on Twitter, amounted to an "unacceptable threat against the world."

A complete lifting of the ban could let potentially billions of dollars in legal claims move forward in U.S. courts and likely antagonize Canada and U.S. European partners, whose companies have significant business holdings in Cuba.

It could also affect some U.S. companies that have begun investing in the island since former President Barack Obama's opening to the old Cold War foe.

Allowing the provision to go into effect even on a limited basis could undermine efforts by Cuban President Miguel Diaz-Canel to foster foreign investment and promote tourism to bolster the Caribbean island’s fragile economy.
