Rodriguez' response Monday was a clear signal that there could be very little, if any, high-level U.S.-Cuba negotiation during Trump's time in office. Already, while working-level meeting on topics such as search-and-rescue have taken place since Trump took office, no meetings between top diplomats have occurred. It's a sharp contrast to Obama's last year, during which top U.S. and Cuban diplomats met regularly to discuss topics including law-enforcement cooperation and compensation for Americans whose property was taken during the 1959 Cuban revolution.
