Several cables in the Baltic Sea and the Taiwan Strait have been severed, with ships linked to Russia and China suspected in each case. While some allege the damage was accidental, the timing, locations, and affiliations point to coordinated disruptions. These incidents exploit gaps in international law, including the 1884 Convention for the Protection of Submarine Telegraph Cables and the UN Convention on the Law of the Sea, which leave jurisdiction unclear beyond territorial waters and exclusive economic zones, according to Forbes. NATO only acted after multiple incidents, launching the Baltic Sentry patrol on January 14th, 2025, underscoring the vulnerability of critical infrastructure. Experts warn that Russia and China are testing how law-abiding states respond to provocations below the threshold of armed conflict, and they urge governments, NATO allies, and Taiwan to prepare both legally and militarily to safeguard global communications and economic stability.

This vulnerability was underscored when Finnish authorities on Wednesday, December 31st, seized the cargo vessel Fitburg, traveling from Russia to Israel, on suspicion of damaging an undersea telecoms cable linking Helsinki and Tallinn. Fourteen crew members of various nationalities are being held as police investigate the incident for aggravated criminal damage and interference with telecommunications. Flying the flag of Saint Vincent and the Grenadines, the vessel reportedly dragged its anchor in Finnish waters, echoing past Baltic incidents involving Russian-linked ships, reports SkyNews. NATO and Finnish officials are monitoring the situation closely, emphasizing the ongoing strategic risks to undersea infrastructure in this sensitive region. They write:

Finnish police have seized a cargo vessel suspected of damaging an undersea cable.

The Fitburg had departed from Russia and was en route to Israel when Finnish authorities detained the ship.

It is suspected of causing damage to a telecoms cable running from Helsinki to Estonia’s capital Tallinn belonging to Finnish telecoms group Elisa. […]

Eight NATO states border the Baltic Sea, which also borders Russia.

They have been on high alert after a spate of power cable outages, telecoms links and gas pipelines that run along the relatively shallow seabed since Russia invaded Ukraine in 2022. […]

The vessel was dragging its anchor in the sea, and was directed to Finnish territorial waters, the police and Finland’s Border Guard stated. […]

In December last year, Finland boarded the Russian-linked oil tanker Eagle S which investigators said had damaged a power cable and several telecoms links in the Baltic Sea by dragging its anchor.

A Finnish court in October dismissed a criminal case against the Eagle S captain and other crew members, ruling prosecutors failed to prove intent and that any alleged negligence must be pursued by the ship’s flag state or the crew’s home countries.
