Invitation accepted from Asia

Besides the Asian football championship that is going to happen early next year at United Arab Emirates, in 2019 we have another two official summer competitions that will play in both American continents. One of them is in Brazil, where it will host one of the oldest official football championship event in the world on the international scene: edition number 46 of Copa America. At the first Thursday in April the organizers have sent an invitation, which is accepted one week later (two days ago) to Qatar to join the event.
As all 10 members in CONMEBOL region are eligible to participate at the tournament, we are needing six more teams to complete the line-up of 16. One spot is already taken and it speculates that in the largest country in South America from 14 June 2019 could also arrive PR China, Japan, Mexico plus two more states.
