Cuba is willing to mend fences with Cold War foe the United States, says President Raul Castro.
At the end of a Revolution Day ceremony marking the 59th anniversary of a failed uprising against a military barracks, Castro on Thursday grabbed the microphone for apparently impromptu remarks.
He echoed previous statements that no topic was off-limits, including US concerns about democracy, freedom of the press and human rights on the island, as long as it is a conversation between equals.
"Any day they want, the table is set. This has already been said through diplomatic channels," Castro said.
"If they want to talk, we will talk."
Washington would have to be prepared to hear Cuba's own complaints about the treatment of those issues in the United States and its European allies, he added.
"We are nobody's colony, nobody's puppet."
Washington and Havana have not had diplomatic relations for five decades, and the 50-year-old US embargo outlaws nearly all trade and travel to the island.
Later on Thursday, Mike Hammer, assistant secretary for public affairs at the US State Department, said that before there could be meaningful engagement, Cuba must institute democratic reforms, improve human rights and release Alan Gross, a Maryland native serving 15 years for bringing satellite and other communications equipment into Cuba illegally while on a USAID-funded democracy-building programme.
"Our message is very clear to the Castro government: They need to begin to allow for the political freedom of expression that the Cuban people demand, and we are prepared to discuss with them how this can be furthered," Hammer said.
"They are the ones ultimately responsible for taking those actions, and today we have not seen them."
Hammer highlighted the brief detention this week of dozens of dissidents outside the funeral of prominent Oswaldo Paya, who died in a car crash last weekend, saying "the authoritarian tendencies are very evident on each and every day in Cuba".
Days after Paya's death, Raul Castro had harsh words for the island's opposition, accusing them of plotting to topple the government.
"Some small factions are doing nothing less than trying to lay the groundwork and hoping that one day what happened in Libya will happen here, what they're trying to make happen in Syria," Castro said.
The July 26 national holiday was often used to make major announcements when Castro's older brother Fidel was president, but there were none on Thursday.
