Mediated public diplomacy and securitisation theory: the US campaign against Chinese 5G in Brazil and Chile

Abstract

Amidst the transition to the fifth generation of mobile telecommunications (5G), the US has launched a diplomatic campaign to prevent other states from acquiring such technologies from Chinese providers. In reply, China has launched a similar campaign to rebut being perceived as a security threat. However, the outcomes of such influencing campaigns in other states have been varied. This article argues that mediated public diplomacy and securitisation theory offer complementary ways to research the competition between the US and China in terms of influencing the policies of foreign states. Empirically, it examines the cases of Brazil and Chile, where the US campaign against Chinese 5G suppliers was successful in setting the agenda. However, neither the increased economic interdependence of Brazil and Chile with China nor their close political cultural congruency with the US, though, are enough to explain the different outcomes of the US campaign against Chinese 5G providers in each country. Indeed, Chile rejected the US securitisation move, while in Brazil it was successful, but partial in that it only refers to government 5G, not commercial 5G. The article argues that the degree of consensus among national political elites and other non-state actors to endorse or reject the US narrative explains such differences.
