American music industry power couple Beyoncé and Jay-Z did not violate US sanctions on Cuba by travelling to the communist-ruled island last year, a US government review has found.

“We found no indication that US sanctions were violated, and we concluded that the decision not to pursue a formal investigation was reasonable,” said the review by the Treasury Department’s Office of Inspector General.

The four-day visit in April 2013 was a cultural trip that was fully licensed by the Treasury Department, organisers said at the time.

The long-standing US trade embargo against Cuba prevents most Americans from travelling to the island without a licence granted by the US government.

Two Cuban-American members of Congress, both Republicans representing south Florida and supporters of a firm stance on Cuba, had asked the Treasury Department for information on what type of licence the couple obtained for their trip.

Beyoncé and Jay-Z celebrated their fifth wedding anniversary in Havana and were greeted by big crowds as they strolled through the Cuban capital. They were instantly recognised despite the past half-century of ideological conflict that separates the two countries.

The visit was planned as a ‘people-to-people’ cultural visit and involved no meetings with Cuban officials, or typical tourist activity such as trips to the beach, organisers said at the time.

The trip included visits with Cuban artists and musicians, as well as several nightclubs where live music was performed, and some of the city’s best privately run restaurants, known as ‘paladares’.

Beyoncé and Jay-Z were among a bevy of American stars to visit the island in recent years, joining actors Bill Murray, Sean Penn and James Caan. But the pair were the first to cause such a stir everywhere they went.

While it has kept the embargo in place, the Obama administration has eased ­restrictions on travel to Cuba for academic, religious or cultural programmes.
