With the ending of the socialist world, that became the last chapter of the Cold War at the beginning of the 1990’s, a large scale economic, technological, social and cultural process named Globalization – whose first steps go back to the second half of the XX century – gathered its forces. Today, globalization is present in International Relations under the robes of economic, political and cultural relations that States maintain among themselves, emphasizing the economic aspect for integrating local economies to a worldwide market economy where production methods and capital movements are configured on a planetary scale, the role played by multinational corporations and the free circulation of capital, together with the definitive implementation a consumer society are gaining greater importance – a “recipe” that several Latin American States above all consider to be unfortunate. Globalization has also reached the legal classification formed by the need to standardize and simplify national and international procedures and regulations with the idea of improving the conditions for legal competition and security, in addition to applying the recognition of fundamental human rights to all people. The globalized culture is characterized by a process that entwines local societies and cultures with an international culture referred to as a global village; given the divergence of criteria being discussed as to whether it is a phenomenon of western assimilation or a multicultural fusion, this is a very controversial subject. On a technological plane, Globalization depends on advances made in human connectivity (transportation and telecommunications), which facilitates free circulation for people and the spread of TICs and Internet. However, the Globalization of International Relations also affects armed conflicts presently in course, as well as military alliances, diplomatic relations, negotiations between international organisations, public coordination in favor of development and international coordination on policies regarding economy, among just a few. Thanks to Globalization, decisions that before were made on a national scale have been transformed into supranational authorities, while others that just a few years back were perceived as strictly national have today reached a level of global involvement. Even though at times it is on a less involved manner (also less restrictive), The Globalization in International Relations seems to be the combined mechanism through which States, civil societies and international organisations interact with each other to respond to individual or collective challenges. And we find a final aspect of Globalization in the following examples. When merchandise is exported today, we travel abroad or surf the web, or when an emigrant abandons his country in search of better opportunities, or when a voluntary worker lends his assistance to a developing nation, these are civil societies, and not States that make contact one with the other: in other words, another manifestation of International Relations in a globalized world.
