This document discusses international trade policy and different approaches countries take. It explains that trade policy exists on a spectrum between free trade, with no restrictions, and protectionism, where governments restrict trade to protect domestic industries. Most countries fall somewhere in between. The document then discusses some key aspects of international trade policy, including tariffs, trade barriers, and different types of policies. It also outlines some rationales for protectionism, such as protecting developing or "sunrise" industries, and strategies for managing non-renewable resources.
