Subsea data cables are the digital lifelines of our modern world. Yet, external factors frequently expose vulnerabilities in the network and its supporting infrastructure. While around 150 cable faults occur globally each year, states suspect a growing number of cable faults to be linked to hybrid or malicious activity. Recognising that many states around the world face similar risks, the EU Action Plan on Cable Security proposes to establish “an advanced cable diplomacy”. But cable diplomacy is not a one-size-fits-all strategy. Technological sensitivities, dual-use aspects and geopolitical considerations demand a tailored approach. Where and how should the EU build effective cable diplomacy partnerships?

The EU and the UK are holding their first post-Brexit summit on 19 May. Since coming to power in July 2024, the focus of Labour’s much-vaunted ‘reset’ with the EU has been on building friendly relations with EU institutions and Member States. Whilst these overtures have been positively received, (substantive) progress has been slow. The summit will therefore be crucial in determining whether the two sides can move from ambition to action.
