Equastria's interactions with other countries

[Firehearted 120]

Does Equastria really interact with other countries? An clear example is with Saddle Arabia but that's it. We never hear about other countries or there doings. All we know is that there are four kingdoms which include: The Griffon Kingdom, The Changling Kingdom, Saddle Arabia, and Equestria. Do they interact? None of them have have played a clear role in Equestria.
