Story highlights In June, President Trump announced he would be rolling back some of the changes made by President Obama

"We have strengthened our Cuba policies to channel economic activity away from the Cuban military," Treasury Secretary Steven Mnuchin said

(CNN) The US government announced additional sanctions and travel restrictions on Cuba Wednesday, following up on an announcement by President Donald Trump earlier this year.

Among the specific changes outlined by the Treasury Department are restrictions on travel to Cuba for educational or cultural exchange groups, which will now be permitted only for sponsored groups in the United States, and with the participation of representatives from those groups.

Individuals traveling for so called "people-to-people" outreach will no longer be able to visit the country, except where travel arrangements have already been made, or in cases where these individuals are accompanied by permitted, US-based sponsors, a senior administration official explained to reporters on a conference call.

"We have strengthened our Cuba policies to channel economic activity away from the Cuban military and to encourage the government to move toward greater political and economic freedom for the Cuban people," Treasury Secretary Steven Mnuchin said in a statement.

The State Department has also published a list of 180 entities including hotels, stores, rum makers, marinas and a economic development zone at the Port of Mariel, which are believed to financially benefit the Cuban military, intelligence and security services and which US citizens will no longer be permitted to frequent.
