The Trump administration is nearing completion of a policy review to determine how far it goes in rolling back former President Barack Obama's engagement with Cuba and could make an announcement next month, according to current and former U.S. officials and people familiar with the discussions.

U.S. President Donald Trump's advisers are crafting recommendations that could call for tightening some of the trade and travel rules that Obama eased in his rapprochement with Havana but which are expected to stop short of breaking diplomatic relations restored in 2015 after more than five decades of hostility, the sources said.

The policy review, coordinated by the National Security Council, is expected pick up steam now that Trump has returned from his first foreign trip, one administration official said, speaking on condition of anonymity.
