Dominican officials said they have confiscated some of the cocaine -transferred by a fast boat destroyed by the US Navy.
The Trump administration, meanwhile, is conducting a controversial anti -drug mission in the South Caribbean.
At a press conference, the Dominican Republic’s National Drug Control Bureau announced that it recovered 377 cocaine packages from the boat, which is said to have 1,000 kg of medicine.
Officials said the boat was destroyed in about 80 sea miles south of Isla Beata, a small island owned by the Dominican Republic.
They said the Dominican Navy has worked with US officials to find a motor boat that is said to be trying to do the dock in the Dominican Republic and the use of the country as a “bridge” to transfer cocaine to the United States.

“This is the first time in the history that the United States and the Dominican Republic are conducting a joint operation against Narco terrorism in the Caribbean,” the department said in a statement.
In August, the United States sent eight warships and a submarine to the South Caribbean, in what the Trump administration said was a mission to combat drug trafficking.
The White House says the vessel has destroyed three motor boats that have so far destroyed drugs in separate strikes that killed more than dozens of people inside the ship.

Human rights groups have said that the strikes of these boats are over -judicial killings, and on Friday, two Democratic senators in Congress submitted a resolution seeking to prevent further strikes.
The Trump administration says at least two boats drowned from Venezuela, whose president is often described by White House officials as a drug trafficker and leader of a gang known as the Sun Cartel.
Venezuelan President Nicholas Maduro denies the allegations and described the construction of the US Navy in the Caribbean as an attack on his country.
