BBC NEWS | Americas | Clinton admits Cuba policy failedUS Secretary of State Hillary Clinton has said that US policy towards Cuba has failed, welcoming an offer to talk from the Cuban president.
She said the US was "taking a serious look" at how to respond to President Raul Castro's comments, which she called an "overture".
Mr Castro had said he was ready for discussions covering human rights, political prisoners and press freedom.
The US passed a law this week easing restrictions on Cuban Americans.
The move will allow Cuban Americans to visit relatives in Cuba and send money home more easily.
Speaking to Latin American leaders in Venezuela on Thursday, President Castro said he had sent word to the US government "in private and in public" that he is open to negotiations as long as they are "on equal terms".
Venezuelan President Hugo Chavez said he would veto the final declaration from the OAS summit because of Cuba's exclusion.
Im seeing a lot more willingess to communicate and more dialogue on the US's part. This is really encouraging.
