Russia and China are mapping NATO cable routes with 'research vessels' and no legal mechanism prevents it

Russian oceanographic vessels (Yantar, Admiral Vladimirsky) have been repeatedly observed loitering near NATO submarine cable routes, likely mapping cable positions for potential wartime sabotage. Under UNCLOS, oceanographic research in international waters is legal, and no treaty prohibits surveying cable locations. NATO cannot prevent this mapping activity because freedom of navigation in international waters is a principle that NATO itself depends on. This persists because the legal framework governing undersea cables (1884 Convention, UNCLOS Articles 112-115) was written for telegraph cables and grants no nation the right to establish exclusion zones around submarine cables in international waters.
