Cuba said on Wednesday it hoped to sign off on at least half a dozen agreements with the United States before businessman Donald Trump, who has threatened to derail detente between the former Cold War foes, becomes president on Jan. 20.

Cuban and U.S. officials held talks in Havana to discuss what more could be accomplished during President Barack Obama’s remaining weeks in office, agreeing to arrange more high-level visits and technical meetings.

The more Cuba and the United States deepen their detente, the more irreversible it will become, analysts said.

“At the moment we are negotiating 12 more (accords) with the aim to be able to conclude and sign a majority of them,” Josefina Vidal, the Cuban foreign ministry’s director of U.S. affairs, told a news conference.

The accords would be in areas such as seismology and meteorology, she said, adding that Cuba and the United States had already signed a dozen accords in the two years since they agreed to normalize relations, ending decades of hostility.

They have also opened embassies, restored commercial flights and opened travel options.

But some fear all that is now at stake, given Republican Trump has said he would seek to reverse the opening unless Communist-ruled Cuba gives the United States what he calls a “better deal.”
