There are very few countries on the Earth that can withstand the pressure (political, economic, intelligence, military) of the hegemon which, again, under the guise of "free trade" pushes his own imperial interests. And those countries are immediately called an "enemy" to the "free world" (euphemism for "US and its vasals NATO and EU"). So, the "international community" (another euphemism for "US and its vasals NATO and EU") has to sanction such a country - applying political and economic pressure. If it's militarly weak, to bomb it - applying intelligence and military pressure, as well. In case you don't know which countries I am talking about, just open your warmongering media - warmongering, as they didn't oppose any war of the empire.
Because of all of this, countries cave in and accept being exploited just to avoid the worst. No matter if is is a mobile phone or gas pipeline.
I'll end with a quote from a former free thinking German politician about how USA enforces its interests: "The manner of thought that takes into regard solely its own interests can only be referred to as totalitarian."
