Free trade and tariff advantages have paved the way to new contents that were not included in international trade agendas initially, but which have become central to negotiations nowadays. Foreign financing of public and strategic projects, judicial review and administrative regulation are new phenomena which have effects that transcend national boundaries. The social market economy based on free competition and deregulation are the ideal scenario to propose new global administrative and economic schemes. International organizations such as the WTO and the OECD have introduced concepts such as the “global administrative law” or the “single global economy”, which deserve to be analyzed from the perspective of public procurement as a fundamental tool of the State to fulfill public purposes. This paper aims to analyze regulatory aspects favorable to globalized interest, as well as solutions to conflicts in spaces that generate greater security and promote foreign investment.
