South America's football body CONMEBOL has refused an offer from U.S. Soccer to organize and host a continental competition in 2020.

A letter signed by CONMEBOL President Alejandro Dominguez tells U.S. Soccer the months of June and July are already reserved for a Copa America edition.

Dominguez also said in the letter revealed Thursday that top football body FIFA did not approve playing a Continental Cup in 2020.

The CONMEBOL president said in the letter the accounting of the Copa Centenario played in the United States three years ago is still to be concluded.

Chile won the centennial Copa America tournament played in the U.S. in 2016.

Brazil will host the next edition of the tournament in June this year, with Japan and Qatar as guests.
