According to the Indonesia Ocean Justice Initiative, between 2018 and January 2021, a large number of Chinese vessels “deactivated” their AIS transponders – the automatic identification systems used to track ships at sea – and engaged in illegal marine scientific research while cruising inside Indonesian waters. Chinese ships even released unmanned underwater vehicles (UUVs), with some of these drones apparently malfunctioning and later discovered by locals while fishing.
As the world’s largest archipelagic country with rich marine biodiversity, Indonesian waters have consistently attracted a large number of countries for scientific research. But China’s activity has caused concern among the Indonesian public, the underwater drones in particular a glipse of activities that otherwise go undetected beneath Indonesian waters.
The 1982 United Nations Convention on the Law of the Sea (UNCLOS) makes no reference to the UUV operations for marine scientific research, although the use of underwater drones is acknowledged in guidelines issued in 2010 by the UN Division for Ocean Affairs and the Law of the Sea, Office of Legal Affairs. UNCLOS does require a “consent regime” be obtained for any third nation wishing to conduct marine research in a coastal state’s territorial water, exclusive economic zone and continental shelf.
Unfortunately, neither UNCLOS or the guidelines distinguishes marine research by civilians or the military.

Apart from scientific applications, UUVs are extensively used by the military. Underwater drones are able to reach otherwise inaccessible locations were a human aboard, and UUVs are capable of conducting reconnaissance and carrying weaponry.
The Chinese People’s Liberation Army-Navy (PLA-N) is keen to develop UUV technology. China is committed to modernising its navy equipment through automation research, with analysts assessing the potential use of UUVs in surveys and reconnaissance, undersea cable inspection, mine warfare and countermeasures, and potentially anti-submarine missions.
With tensions in the South China Sea over competing territorial claims, the potential for UUVs to become a trigger for a wider conflagration cannot be discounted. Already in 2016, the PLA-N unlawfully seized a UUV from the USNS Bowditch in international waters northwest of Subic Bay, Philippines, alleging that the US Navy was conducting reconnaissance of China’s maritime activities. The US said it was performing a military survey in international waters, not Chinese waters, which is permissible under UNCLOS and the subsequent guidelines.
