Interesting concept. Large countries are controlled by wealthy people and corporations, but even a small country has more resources than many larger businesses. So, a small country can threaten businesses that control a larger country in order to influence the larger country.

So, there are two outcomes that I can see. Either the larger country is played by the smaller country, or the larger country pays even more to the business, causing further inequality and dissatisfaction among the masses. Or I guess the large country could abandon the business. So that's three obvious possibilities.
