What Lies Beneath: Hybrid Threats to Taiwan’s Submarine Cables and the Contest in the Information Domain

Between 2023 and 2025, multiple disruptions affected Taiwan’s submarine cables, a critical yet vulnerable infrastructure essential to the island’s connectivity and security. Against the backdrop of China’s diplomatic, economic and military pressure targeting Taiwan, these disruptions are generally defined as “grey zone operations”. Yet, reframing them as hybrid threats allows for a better understanding of how specific threats to the infrastructure domain can spill over in the information domain. Disruptions to submarine cables may be exploited by threat actors to erode trust in domestic institutions and destabilise society. Uncertainty in the information domain emerging from these disruption presents opportunities for Taiwanese authorities to mobilise public support, international partners and resources to enhance infrastructure resilience. A strategic communications approach drawing on the experience of the EU can strengthen response through enhanced coordination among institutions, coherent messaging, constructive public engagement and improved awareness of information-domain contestation. An effective adoption of this approach may mitigate risks from threat actors while reinforcing the capacity of Taiwanese authorities to safeguard critical infrastructure and maintain societal trust.
