Cameroon head coach Hugo Broos wants Joel Matip to return to the national team after the Africa Cup of Nations.
The Liverpool defender, 25, was one of seven players to say they did not want to play in the tournament after being selected in the preliminary squad.
He has not played for Cameroon since 2015, but Broos told BBC Sport: "I hope he will change his mind."
Matip was cleared to play for Liverpool by Fifa on Friday after confusion over his availability during the tournament.
Cameroon said he had refused a call-up and Fifa rules state a player may be blocked from featuring for his club if he refuses to play for his country - but world football's governing body dismissed the case.
