China’s survey activity near Pacific undersea cables raises risks for Big Tech

A CSIS analysis of 200 research vessels from 47 countries found Chinese ships spent a significantly larger share of time near critical undersea infrastructure than vessels from other nations. One Xiang Yang Hong vessel operated near three Pacific cables between July and October 2024. Analysts say repeated survey patterns could map the seabed and potentially support submarine operations or sabotage planning, but the report does not prove sabotage occurred. The findings highlight risks for major technology firms
