Some activist groups believe that GATS risks undermining the ability and authority of governments to regulate commercial activities within their own borders, which will lead to the flight of power from the commercial interests of citizens. In 2003, the GATSwatch network published a critical opinion, supported by more than 500 organizations in 60 countries.  At the same time, countries are not required to enter into international agreements such as the GATS. For countries that like to attract trade and investment, GATS adds a degree of transparency and legal predictability. Legal barriers to trade in services may have legitimate political reasons, but they can also be an effective instrument for large-scale corruption.  The GATS aims to establish a strong multilateral framework or principles and rules for trade in services. Many countries have laws that directly restrict access to foreign service companies in areas such as finance, media, communications, transport, etc. Services that, even across borders, lead from one country to another, for example. B, distance education, advice, OPL services.
Transparency: GATS members are required, among other things, to publish all measures of general application and to set up national investigative bodies to respond to requests for information from other members. The GATS expressly recognizes the right of members to regulate service delivery by pursuing their own policy objectives. However, the agreement contains provisions to ensure that service rules are managed appropriately, objectively and impartially. Exceptions may be granted in the form of Article II exceptions. Members could apply for such exemptions before the agreement came into force. New derogations may only be granted to new members at the time of accession or, in the case of current members, by a derogation under Article IX:3 of the WTO agreement. All exceptions are subject to review; they should not, in principle, last more than 10 years. In addition, the GATS allows groups of members to enter into economic integration agreements or to mutually recognize regulatory standards, certificates and others when certain conditions are met. MFN Treatment: Article II of the GATS authorizes members to treat the service providers of all other members without delay and unconditionally, “a treatment that is no less favourable than that given to comparable service providers in another country.” In principle, this is a prohibition of preferential regimes between groups of members in certain sectors or reciprocity rules that limit access to the dense to trading partners who give similar treatment. It is a foreigner who provides services such as a doctor, a nurse, a computer engineer, etc., who works as a consultant, collaborator, from one country to another.
The GATS defines services in four “types of supply”: cross-border trade, consumption abroad, commercial presence and the presence of individuals.
