US President Barack Obama seized on an extraordinary overture from Cuba to propose talks aimed at breaking the half-century hostility born between Washington and Havana during the Cold War. He told a Summit of the Americas with Latin American leaders in Trinidad and Tobago on Friday that he wanted to establish “a new beginning” with Cuba that would recognize past US “errors,” but require reciprocal gestures from the communist island. The conciliatory language raised the prospect of the United States considering ending to its 47-year-old embargo on Cuba.

Obama, who early this week lifted curbs on Cuba-Americans' contacts with Cuba, said Havana still had to give some concrete signs it was willing to engage. He stressed, though, that the United States had changed from its Cold War days, and was “willing to acknowledge past errors, where those errors have been made.” He stopped short of discussing the possibility of lifting the 47-year
