SANTIAGO, Chile -- The 2019 Copa America will consist of 16 teams under a measure approved on Wednesday by CONMEBOL.

Football's governing body in South America only has 10 members and have previously invited two other countries to play in their regional international cup. Mexico have played in the Copa America since 1993.

The standard 12-team field for the South American championship was broken last year with 16 teams playing in a special 100-year anniversary edition in the United States. The additional teams came from CONCACAF, the North and Central American and Caribbean region.

Brazil are the hosts for the next edition in 2019, when the expansion will make it easier to invite teams from other regions of the world.
