Cuba’s government said Tuesday that months of negotiations with the United States, which is applying maximum pressure to the island to try to bring about a change in governance, had shown “no progress.”

“The discussions between the Cuban and US governments are showing no progress,” Foreign Minister Bruno Rodriguez told a press conference, adding that “despite all that” Havana “will remain open to dialogue.”

US has cranked up pressure on the island in recent months, imposing an energy blockade and sanctions that deepened an already dire economic crisis. President Trump has made clear he would like to see a change of leadership, pointing to Washington’s overthrow of Venezuela’s socialist president Nicolas Maduro and installation of a Washington-friendly successor as a possible blueprint for what he would like to achieve in Cuba.

Cuba’s government earlier this month pushed through a batch of major free-market reforms but has repeatedly said its political model is not up for discussion and vowed to resist any invasion militarily.
