It's an extremely proud, nationalistic country. There's strong traditionally masculine elements here.
That means a culture that can be kind of xenophobic, violent, and aggressive.
Despite that, I actually like it. I like traditionally masculine, proud, nationalistic countries. I know that isn't fashionable to say in this day and age, but after having been around a lot of the world, I just feel really bad for the citizens of countries that are totally pacified and unproud. The men move through life in a sort of drudgery and haze, and the women don't seem to enjoy those state of affairs either.
That said, pride/nationalism/hyper-masculine mixed with transitioning out of poverty can lead to bad places. It's not so much nationalism that is bad, as much as it's a catalyst for whatever else is happening in the society. In a country in a renaissance or golden age, with an emphasis on expansion, science, commerce, innovation, hard work, and building wealth, nationalism and pride becomes a force for progress. In a country that's on the down and out, nationalism amplifies that to bad result.
Mongolia is interesting. Their national holiday, Naadam, is a festival in July featuring wrestling, horseback riding, and archery.
