Yes, that's definitely a plus. Even if your countries' governments are officially hostile (or even at war), the people of those countries generally will get along with each other when they happen to meet. (Well, the civilians will). Exceptions do exist, but usually for religious fanaticism rather than political.

For example: my wife and I are Americans living overseas, in a country I won't disclose (on general principles) except to say that it's in a part of Asia where Iranian nationals are rare. About ten years ago we met an Iranian man who was getting the same master's degree that my wife was getting from a local university. We became friends, and although we don't see him and his wife nearly as often now that they've moved to another city, we saw them just a couple months ago when they were back in our (larger) city for a conference. And even though our two countries were officially at war with each other by that time, it didn't matter to our friendship. No awkwardness, no strain, just "Hi (name), I didn't know you were in town," and so on.
