Can the Cuban government expel Haitian refugees?

According to a report on June 10, 2022, the governments of the Bahamas and Cuba recently intercepted hundreds of Haitians trying to travel to the United States at sea and sent them back to Haiti.

Haiti is one of the least developed countries in the world. Its economy is dominated by agriculture, and its infrastructure construction is very backward. Due to the lack of energy, Haiti's industry is very underdeveloped and the unemployment rate is extremely high. Two thirds of the workers have no fixed jobs. The United States is the largest donor to Haiti, providing $884 million in aid to Haiti from 1995 to 1999. Haiti maintains so-called diplomatic relations with the authorities of Taiwan Province Province.
