The 19-year-old has been called up by Zimbabwe for their matches against Lesotho and Namibia.
Benyu, who was signed from Ipswich in the summer could have played for England but opted to play for the African nation instead, and has been rewarded with his first call-up.
Zimbabwe manager Wilson Mutekede is thrilled that the Hoops youngster elected to play for them.
He told The Scottish Sun “We are absolutely delighted Kundai has chosen to play for us.
“We are looking forward to seeing him next week.”
Benyu made his Scottish Premiership debut for Celtic against Kilmarnock back in August but hasn’t featured often since.
The player has mostly been part of Celtic’s development squad for this season and recently featured in the 2-1 Premier League International Cup victory over Athletic Bilbao.
He is seen as one for the future, who isn’t yet ready for regular first team football.
Celtic’s next fixture, after the heartbreaking 2-1 Champions League Group Stage defeat to Bayern Munich, will see them attempt to make history.
If the Bhoys avoid defeat to St Johnstone on Saturday they will break the record of 62 unbeaten domestic matches, originally set 100 years ago.
