Berti Vogts announced the decision, as predicted by Glenn earlier in the week, and it comes as a reward for how well he has done in a Scotland shirt since the German took over - as well as recognising his efforts in a West Ham shirt, where he was ever present this season.
Ironically, the appointment is partly due to the absence of Don Hutchison from the tour of the far east; the erstwhile Scotland captain is, of course, undergoing long term rehabilitation at West Ham and will not play again until well into next season.
Christian, who scored against Nigeria in the last Scotland game prior to their encounter with South Korea that kicked off their tour, has previously captained his country at U15, U16, and U21 levels.
Says Glenn:
"We're all pleased for Christian; it is a fantastic honour for him to be made Scotland's captain, and after the season he has had here he thoroughly deserves it.
"I couldn't wish to work with a better professional; he is terrific to have around the place and has improved greatly this year, and I think he will say that himself.
"Under the new structure, if you want, he is certainly a player that enjoyed the work we have done with him on the training ground.
"I think he has become very consistent, which is all you want from defenders; you want them to be safe, and Christian has done that.
"Him and Tomas have done really well, and at West Ham we are very pro players playing for their country; we want the honour for them and we want the honour for the football club, and for us to have Scotland's new captain is terrific."
Scotland lost 4-1 to South Korea in the first game of the tour.
