I think international friendship means International Agreement in this quote

I disagree with Sarah Bertram. The sentence is confused and mixes point of view. The program can serve a dual purpose. I can both share my concerns over the protection of our heritage and make friends with others around the world.

I think so. It might be clearer to say something like: ***This program will not only let me show my heritage and culture, but also give me international friendship.*** But overall for the most part it makes sense! (Good job!)
