In recent months, China has sparked a major maritime confrontation with Indonesia near the South China Sea with dozens of Chinese fishing vessels, along with a coast guard escort, entering waters off the Natuna Islands, which are within Indonesia’s exclusive economic zone but are also claimed by China.
The Natuna Regency is an archipelago of 272 islands located in the south part of the South China Sea in the Natuna Sea.
It is part of the larger Tudjuh Archipelago, off the northwest coast of Borneo.
Administratively, the islands constitute a regency within the Riau Islands Province of Indonesia.
Important Info : Maritime administration and Chinese claim
Indonesia's exclusive economic zone (EEZ) off the coast of Natuna is slightly overlapped by China's widely disputed South China Sea claim.
Indonesia's EEZ extends 200 nautical miles (370 km) from its shores, which around Natuna means it is slightly intersected by China's Nine-Dash Line, defining its widely disputed claim to most of the South China Sea.
