This is the network of critical underseas cables at the mercy of Chinese and Russian saboteurs - and the multiple ways they could be attacked.
A new report has warned Britain remains 'woefully' underprepared for the threat of strikes on its maritime infrastructure in the face of growing aggression.
The China Strategic Risks Institute (CSRI) looked at 12 incidents of alleged undersea cable sabotage between January 2021 and April 2025 in Europe and Taiwan.
Out of the 10 cases where a suspect vessel was identified, eight were linked to China or Russia by flag or ownership.
Report author Andrew Yeh said the involvement of Chinese ships in cable breakages in Europe and Russian ships in those near Taiwan indicated 'plausible' coordination.
