Cyber issues are a core national security policy concern in many countries, not least Russia which is seeking deeper digital cooperation within BRICS (prior to 2024 consisting of Brazil, Russia, India, China and South Africa). This report examines (1) the cyber infrastructure choices made by BRICS members; (2) their justifications for these choices; (3) these countries' inclination to deepen digital cooperation; and (4) their proposed or implemented measures to regulate the Internet. China's economic power and advanced technological development make it a dominant actor within BRICS, and Beijing, like Moscow, aims to weaken Western influence and increase state control over the Internet. While Brazil, India and South Africa also want diminish Western dominance, they stop short of distancing themselves completely from the West. Instead, their foreign policy hedging allows them to secure access to both Western and Chinese technology. Future U.S. policies, along with the BRICS countries' domestic policy choices, will influence the likelihood of deepening digital cooperation. Furthermore, the inclusion of new members will impact the internal BRICS dynamics, and the infrastructure choices made by its members will be key. So far, digital cooperation remains limited, but the factors abovementioned will affect whether the Internet will fragment along geopolitical fault lines.
