The World Trade Organization (WTO) is an international organization that helps to promote fair and free trade between countries. It does this by working to minimize obstacles to international trade and investment. This means that it helps to remove things that get in the way of countries doing business with each other, such as tariffs (taxes on imported goods) and trade restrictions. The WTO also works to ensure that countries play by the same rules when it comes to trade, which helps to level the playing field for all countries. The ultimate goal of the WTO is to help increase economic growth and development around the world by making it easier for countries to trade with each other.
