US Secretary of State Hillary Clinton has said that US policy towards Cuba has failed, welcoming an offer to talk from the Cuban president.
Mrs Clinton made her comments about Cuba in the Dominican Republic, ahead of the Summit of the Americas that begins in Trinidad and Tobago later on Friday.
"We are continuing to look for productive ways forward because we view the present policy as having failed," she said at a press conference.
"We welcome [Raul Castro's] comments and the overture they represent, and we are taking a very serious look at how to respond," Mrs Clinton said.
OAS Secretary-General Jose Miguel Insulza said on Friday he would ask the organisation's members to readmit Cuba, 47 years after it was suspended.
Venezuelan President Hugo Chavez said he would veto the final declaration from the OAS summit because of Cuba's exclusion.
