The 23-year-old, who was born to Ghanaian parents in Hamburg, Germany, will line up for Black Stars in their upcoming double-header of friendlies.
"Great award for Okyere Wriedt! The top scorer of the amateurs of Bayern has been selected for the upcoming international matches of the national team of Ghana," the Bundesliga giants announced via their official website on Tuesday.
"The team of coach Kwesi Appiah will test themselves against two World Cup participants.
"Ghana meet Japan on May 30 in Yokohama.
"They then play the Iceland national team in Reykjavik on 7 June."
The call-up comes just few days after the striker announced his readiness to represent the country of his parents.
He recently held talks with Ghana assistant coach Ibrahim Tanko over his international future.
"I am very happy and proud to have been selected for the national team," Wriedt said upon his call-up.
"For me and especially for my family, it means a lot to be able to represent my homeland."
Wriedt, who joined the German champions on a three-year deal last year, became only the second African to play for the Bavarians after compatriot Sammy Kuffour (1993-2005), when he made his first team debut against RB Leipzig in the German Cup last October.
A month later, he made his Bundesliga bow against Borussia Monchengladbach.
Due to limited opportunities at Allianz Arena, the striker has spent most of his time with Bayern's second team, for whom he has racked an incredible 21 league goals in 28 appearances.
