It notes that the service sector currently accounts for over 80% of the US economy and 40% of the world economy. It also discusses how countries that previously had trade surpluses in manufacturing goods are now facing increasing trade deficits in services with the US. The document uses US and WTO data to analyze trends in US trade in services and examines whether countries are employing protectionist measures to create barriers to trade in services, as has been done with other sectors. It provides examples of the growth of the service sector in the economies of countries like China and discusses how trade in services impacts US competitiveness.
