Jean would like to buy a lot of refrigerators from Mehmet (who makes good refrigerators cheaply in Turkey) for his (Jean's) customers in France.
But he can't. Or if he can, he has to pay more for them than if . . . their respective countries' governments weren't feuding over a historical matter (the killing of Armenians by Turks a hundred years ago). The French government just passed a law making it a crime to say that "it" wasn't "genocide."
So the Turkish government (or the French, or both) interfere with Jean and Mehmet's conspiracy to provide better refrigerators to French consumers while providing gainful employment to Turkish workers.
So it goes.
