During the past eight months of the global COVID pandemic, the Chinese People’s Liberation Army (PLA) has been active in promoting China’s claims in the South China Sea. This essay evaluates PLA statements, military exercises and operations, and deployment of relevant platforms and weapons in the South China Sea during this period. I leverage Chinese-language sources in addition to my own operational knowledge from over a decade of military experience to provide greater context for these activities. I argue that the greatest change in the PLA’s role in the South China Sea has not been operational. Instead, the most interesting development has been the fact that the PLA has taken on a more significant signaling role. Specifically, the Chinese military seems to be purposefully using, and perhaps even exaggerating, its capabilities and activities to enhance deterrence against the United States. This may be seen as necessary as the US increases its own efforts to push back on China’s militarization of the South China Sea. In other words, the PLA has taken a more active role in China’s South China Sea strategy, but not necessarily a more aggressive one.
