Which international regulation is specifically about services and trade?

The correct answer focuses on the General Agreement on Trade in Services (GATS). This regulation is specifically designed to address services and trade at the international level. GATS was established as part of the Uruguay Round of trade negotiations under the World Trade Organization (WTO) and aims to promote and facilitate trade in services among member countries.

GATS covers a wide range of services, including those in sectors such as finance, telecommunications, tourism, and professional services, recognizing the growing importance of services in the global economy. It creates a framework that allows countries to negotiate specific agreements that can remove barriers to trade in services, thereby enhancing economic cooperation and ensuring greater market access.

In contrast, the other options focus on different aspects of international trade, such as goods (General Agreement on Tariffs and Trade), overall economic policy principles (Washington Consensus), or specific regional trade agreements (North American Free Trade Agreement), which do not specifically target services. Thus, the General Agreement on Trade in Services is distinct in its concentration on the trade of services internationally, making it the correct answer.
