The statements come after on Thursday, the 1996 US Helms-Burton Act, which has been partially suspended since its enactment, came into full effect.

Following the United States first announcement of the intention to remove restrictions from the law being enforced, EU foreign policy chief Federica Mogherini and EU Commissioner for Trade Cecilia Malmstrom condemned the proposed action.

As of mid-April, there were some 6,000 claims for properties confiscated in Cuba with a total value of around $2 billion and in the $8 billion range with interest, according to US Assistant Secretary of State for Western Hemisphere Affairs Kimberly Breier.
