According to The Wall Street Journal, the two countries have already reached an agreement. The White House says that information "is not correct".

The U.S. Embassy in Havana has not commented so far on the information.

It comes to light weeks after the passage of a Chinese hot air balloon over US territory. The plane was shot down in February by the US air force over territorial waters.
