In their response to the incident, the U.S. Congress passed the Helms–Burton Act in March 1996. The bill strengthened an embargo against imports of Cuban products. Title III, however, made the bill controversial because it allowed American citizens whose property was seized during and after the 1959 Cuban Revolution to sue in American courts foreign companies that later invested in those properties. Title III sparked an immediate uproar from countries such as Mexico, Canada, and members of the European Union because they believed that they would be penalized for doing business with Cuba. In response, Clinton repeatedly suspended Title III of the legislation (the act gave the president the right to exercise this option every six months).
