"There will be very clear language also on what the Cubans still have to do... releasing prisoners, really working on human rights questions," Ferrer-Waldner told reporters at an EU summit in Brussels.

"There will be a sort of review to see whether indeed something will have happened."

Spain, which restored diplomatic relations with Havana last year, had championed the move to get the sanctions lifted.

'Cosmetic' changes

The US has imposed strict economic and political sanctions on Cuba for 50 years and the EU moves is unlikely to affect Washington's position.

Tom Casey, spokesman for the US state department, said the US opposed moves in favour of Cuba, which he said remains an authoritarian regime, despite recent reforms.

Speaking to reporters Casey said that while there had been "some very minor cosmetic changes" brought in since Raul Castro too power, there was no indication of a fundamental break with communism as practiced by his predecessor, Fidel Castro.

The EU sanctions were introduced after Cuba's government rounded up 75 dissidents in 2003.

Sixteen of those arrested have been released on medical parole and another four were freed last month into forced exile in Spain.

The remaining 55 are are still serving long prison sentences.
