HAVANA (AP) — The lead negotiator in the Cuban government’s talks with the U.S. says the American presidential campaign has added some uncertainty into how she views her country’s future relations with its northern neighbor.

Josefina Vidal is director of the Cuban Foreign Ministry’s United States Division.

She tells the official Cuban News Agency that if President Barack Obama speeds up the dismantling of existing U.S. sanctions on the island while he’s still in power, the ties will be less vulnerable after he leaves office.

Vidal said Tuesday that she will "continue working with a high dose of momentum and optimism."

But she adds that she’s feeling "a certain bit of realism" as next year’s U.S. presidential contest nears.
