Earlier this month, an unidentified underwater drone found in the Selayar Waters of South Sulawesi captured the attention of Indonesian media. The occasion was the third occurrence that a foreign drone, also known as a ‘sea glider,’ was found in the nation’s waters. Needless to say, the discovery triggered a country-wide public furious and strong backlash from the Indonesian parliament members – especially upon heightened suspicion of the drone’s origin.

Against this backdrop, how does the international law of the seas or UNCLOS governs the use of such drone or the types alike in foreign territories? Can it be classified as an official foreign intrusion? What kind of appropriate response should the Government of Indonesia employ? And how can Indonesia prevent future intrusion or illegal activities conducted by foreign entities into its sovereign territory?

FPCI Research Associate Calvin Khoe interviewed Prof. Hasjim Djalal, Indonesia’s foremost expert on the International Law of the Sea and former Indonesian Ambassador to Canada, Germany, and Ambassador-at-large for International Law of the Sea and Maritime Affairs.
