The increasing dispute between the United States of America and China finds a main area of competition around 5G, which will enable a substantial improvement in the capacity for vehicle auto-guidance, remote operations, robotics, artificial intelligence and other dual-use applications. While 5G is still emerging, the global shaping of the network infrastructure, regulations, patents and standards involves the Global South. It is an eminently global dispute for markets, but also for national security, which has gained a central place on the foreign policy agenda of most of the countries around the globe. In this context, the objective of this text is to analyze the emergent conditions of 5G in two of the main countries of the Global South, India and Brazil, within the dispute between the US and China. Through the contextualization of this dispute and its implications in India and Brazil, we seek to extract a series of preliminary reflections for other countries of the Global South. Thus, this paper contributes to a key area understanding the emergent conditions of a new phase of the mobile telecommunications paradigm developing two main cases still unexplored systematically by the literature in Spanish.
