The Castro government is interested in talking to the United States, a delegation of black members of Congress said Tuesday, returning from a five-day trip to Cuba where they met with Raúl and Fidel Castro.

But members of the Congressional Black Caucus said they didn't discuss whether Cuba was prepared to offer any concessions in return.

''We didn't get into any of the details,'' said caucus chairwoman Rep. Barbara Lee, D-Calif., who led the trip. ``We just want to see a dialogue. You don't have to offer anything to talk.''

The group of seven lawmakers, which included six members of the Congressional Black Caucus, spent four hours with Raúl Castro, including dinner. Three members met separately with Fidel Castro at his home. They described the aging leader as ``very engaging, very energetic . . . very talkative.''

The visit marked the first meeting between Raúl Castro and U.S. lawmakers since he took the helm of the country a year ago and the first with the elder Castro since he took ill in 2006.

`TIME TO TALK'

''It's time to talk to Cuba,'' Lee said. 'We are convinced, based on the meetings, that the Cubans do want dialogue, they do want talks and they do want normal relations with the United States of America and I believe it's in the United States' best interest to do that.''

The visit came as President Barack Obama is expected to soon ease family travel and remittances restrictions to Cuba and as both chambers of Congress consider bills that would permit all Americans to travel freely to Cuba.

''This is the dawning of a new day,'' said Rep. Bobby Rush, D-Ill.

The members of Congress said they plan to brief Obama and Secretary of State Hillary Clinton on the trip -- and push the administration to go further.

Lee called Obama's plan to lift family restrictions ''a necessary first step.'' Obama said during the campaign that he does not plan to lift the decades-old economic embargo against the island and Vice President Joe Biden reiterated those remarks last month when he traveled to Chile. Supporters of current U.S. policy say Cuba must make concessions such as scheduling free elections and releasing political prisoners before the United States makes a move.

But Lee said she hopes to tell the administration ``why we believe a full lifting of travel restrictions and the embargo makes a heck of a sense and the moment is now to do it.''

She said she was ``convinced the Cubans want this also . . . We found an openness and a willingness to engage in all forms of normal relations . . . ''

She said the group was not in Cuba to negotiate conditions for engaging.

''But what we're saying is two sovereign nations should be able to talk about their differences and what they have in common,'' she said, adding that Raúl Castro told the group, ``everything's on the table. Discussions, dialogue, no preconditions. We'll talk about all the issues that need to be addressed as long as there is mutual respect.''

Rep. Laura Richardson, D-Calif., said Fidel Castro ''looked directly into our eyes'' and asked how Cuba could help Obama change U.S-Cuba policy.

She said she was left with the impression that the 82-year-old Fidel wants to see changes in U.S.-Cuba relations in his lifetime.

DIDN'T MEET DISSIDENTS

Groups that support current U.S. policy had called on the delegation to visit with black political prisoners on the island, but Rep. Mel Watt, D-N.C., said the group was interested in ''cultivating a discussion to be able to talk about the issues Afro-Cubans are raising.'' The lawmakers did not meet with any Cuban dissidents.

Rush said Raúl Castro was ''very engaging'' and "laughed at himself.

''He was a down-to-earth kind man, someone who I would favor as a neighbor,'' Rush said. He said Raúl Castro told the delegation he would welcome U.S. industry, "He said he'd like to see manufacturing plants.

Lee said Fidel Castro appeared ''very healthy, very clear thinking.'' Richardson noted that he had a full head of hair and surprised her when he knew her name and congressional district.
