The document discusses trade liberalization efforts from the Great Depression era to the present. It describes how the Smoot-Hawley Tariff Act exacerbated the Great Depression by sparking a trade war. In response, the Reciprocal Trade Agreement Act of 1934 started negotiating bilateral trade deals. After World War 2, the General Agreement on Tariffs and Trade was signed in 1947 to liberalize global trade, resulting in several negotiation rounds cutting tariffs. The World Trade Organization was established in 1995 as a permanent institution to oversee international trade, including dispute settlement. Criticisms of the WTO include undermining sovereignty and environmental/inequality concerns.
