I'm afraid I have to start by confessing that the sections of the paper that you read must have been written by my co-authors. I wasn't responsible for those myself.
Rightly so, there's an awful lot of people asking what role DFIs can play to stabilize situations where you have large refugee populations and sources of instability. Other than giving a generic answer along the lines that one of the things you could ask your DFI to do would be to look for opportunities to create businesses in those sorts of situations, I'm not sure any more tighter alignment than that is necessary.
I infer from your question that the United States felt that it had a particular strategic interest in Georgia. If Canada feels that it has a particular strategic interest in particular territories, the DFI could be asked to look for opportunities in those territories in particular. However, you have to recall that, again, DFIs cannot create investable opportunities.
I have heard other DFIs complaining about the fact that they are asked to do something about refugee crises or an instability and they find that there's not a lot they can do. I even had one DFI tell me that they are sometimes put under pressure to make up a story that they've done something useful when they really haven't. That's just a word of caution about what you can expect from a DFI in those situations.
