Last Updated: Chinese Research Vessel Intercepted In Indonesian Waters; Hints At Underwater Ops A Chinese survey ship was caught “running dark” in Indonesian waters without broadcasting its position through AIS, amid concerns of Beijing's maritime behavior A Chinese government survey ship was caught “running dark” in Indonesian waters without broadcasting its position through AIS (Automated Information System), amid concerns of Beijing's maritime behaviour. This is the latest twist to China's ongoing naval invasion, which has also witnessed uncrewed underwater vehicles (UUVs) discovered several times in Indonesia’s territorial waters. The survey ship, Xiang Yang Hong 03 that left its base at Sanya, China, on the morning of January 6, was intercepted by the Indonesian Coast Guard near the Sunda Strait on January 11. All ships transiting the strategically important strait are required to broadcast their position on AIS. When confronted, the crew of Xiang Yang Hong 03 reportedly claimed that its AIS was damaged.
