Talks between the United States and Cuba on the thorny issue of immigration, suspended since 2003, are set to restart today at the UN headquarters in New York.
"They will resume tomorrow," a US official, who requested anonymity, told AFP on Monday, adding that the discussions will take place at the United Nations building in Manhattan.
The move to thaw relations follows Obama's decision in April to authorize travel and money transfers to the island by US nationals of Cuban descent.
In early June, the White House welcomed Havana's agreement to resume talks on migratory issues, but the US official on Monday did not confirm the talks would also include the subject of a direct mail service between the two countries.
"Obviously, it's in the interest of both governments," said President Barack Obama's spokesman Robert Gibbs last month.
"Obviously, I think direct mail would increase the ability for the president's initiative to be able to reach out directly to the Cuban people," Gibbs added.
Mail between the two countries currently goes through third countries.
