This article is a little dated but I thought it applied well to monopolies and their power, only on a larger international scale. The article, from Business Week, is entitled, “Gazprom and Ukraine Settle Gas Dispute.” It basically outlined how much power the Russian government had over Ukraine because of their dependence on the gas that was produced by the state-controlled monopoly at Gazprom in Russia. The dispute arose over debt that Ukraine claimed they would be unable to pay so Russia threatened to cut off their gas supply and are requiring Ukraine to pay-up by transferring some of their gas from storage facilities to Gazprom. Not only did this worry Ukraine, but the European Union as well since a quarter of their gas comes from Russia and eighty percent of the gas is transported through Ukraine.
So here we see a monopoly run by a country exercising power over another country to get them to repay debt and act in a way that they desire. While government run enterprises tend to be inefficient, in this case, it gives them greater power on an international level. For further information, click HERE to visit the article.
