Earlier this month, Cuban President Raul Castro threw his support behind other leftist Latin American governments willing to give asylum to Snowden, who has since sought temporary asylum in Russia. Castro did not say whether Cuba would offer him refuge or safe passage, a key issue since Snowden's simplest route to Latin America might be one of five direct flights that Russian carrier Aeroflot operates to Havana each week.
Then this week, Panamanian authorities seized a ship that had departed Cuba en route to North Korea with a cargo of missiles and other arms hidden under sacks of sugar. Cuba claimed the military equipment was obsolete weaponry from the mid-20th century that it was sending to be repaired in North Korea. The incident underscored concerns about Cuba's relationship with North Korea, which is in a standoff with the U.S. and its allies for continuing to develop nuclear weapons.
Cuba's delegation to the migration talks said the discussion took place in a "climate of respect" and said it was willing to hold more exchanges in the future.
Marie Harf, deputy spokeswoman at the State Department, said the discussion focused on the implementation of the 1994 and 1995 U.S.-Cuba Migration accords. The talks are intended to monitor adherence to a 16-year-old agreement under which the U.S. issues 20,000 emigration visas to Cubans each year.
Wednesday marked the first time since January 2011 that the periodic talks have been held.
"The U.S. delegation highlighted areas of successful cooperation in migration, including advances in aviation safety and visa processing, while also identifying actions needed to ensure that the goals of the accords are fully met, especially those having to do with safeguarding the lives of intending immigrants," Harf said.
Cuba, however, remains on the U.S. list of state sponsors of terrorism. In 2001, five Cuban intelligence agents were convicted of spying on exile groups, politicians and U.S. military installations in Florida. Four of those men remain in U.S. prisons. Havana denies any links to terrorism and contends its inclusion on the list is a political vendetta. In Cuba, the spies are celebrated as heroes.
