The aim of this paper is to analyze the worlds total trade in services and import and export of services globally. The General Agreement on Trade in Services (GATS) which is very important for the development of global trade in services was signed during the Uruguay Round. Its importance lies in establishing rules to ensure the removal of unnecessary barriers to trade in services. Its provisions ensure that transition countries achieve greater flexibility in the implementation of policies on economic integration and to be more competitive int he services market. The paper analyzes the concept and characteristics of services, the World Trade Organization (WTO) and two agreements on trade in services, GATS and TISA ( Agreement on Trade in Services). In the last part it analyzes the trade in services from 2005 2015, the import and export of goods and services, import and export of trade in services for 5 countries with the largest import and export of services and import and export of certain types of services (transport, tourism, insurance services, financial and business). It was found that future development of trade in services on the global level depends on the future development of technologies and market conditions, and that in the period between 2005 - 2015, the value of imports and exports of all kinds of services had increased. The EU and the United States are leading countries in trade in services worldwide, and fast growing Asian economies are increasingly approaching them.
