Abstract
World trade rules form the playbook for countries buying and selling to one another, and they often spark economic fire. Pour on high tariffs or scribble a new free-trade pact, and customs gates swing open; tighten red tape, and the borders slam shut. Recent headlines show that welcoming policies can flip to protective ones almost overnight, and giant joint talks add another layer of twists. Those jolts are already yanking supply chains sideways-from the family farm all the way to the factory floor. Stay on top of these shifts, and planners still stand a fighting chance at steady, long-term growth even in a crowded global marketplace.
