Spain is concerned about Washington’s possible decision to allow US citizens to sue foreign firms doing business in Cuba, Spanish Foreign Minister Josep Borrell told the US administration, Reuters reported.

The US decision concerns the use of property confiscated by the Cuban government after the 1959 revolution.

Last month, US President Donald Trump allowed such lawsuits, increasing pressure on Cuba. However, the prohibition of lawsuits against foreign firms using confiscated property remains in effect until April 17, while Washington reconsiders this decision.

Among the foreign companies heavily invested in Cuba, a former Spanish colony, is Spain’s Melia Hotels.

Borrell met with U.S. national security advisor John Bolton in Washington on Wednesday and with Secretary of State Mike Pompeo.

At these meetings, Borrell expressed concern about the negative consequences that the above measure would have for the interests of Spain.

“Spain reiterates its firm rejection, as a matter of principle, to the extraterritorial application of national sanction laws, considering it contrary to international law,” it added.

Every US 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.
