evidence: Indonesia’s position is clear that it is not a claimant to any features in the South China Sea, so has no pending maritime delimitation with China. Nonetheless, China unilaterally insists that Indonesia’s exclusive economic zone (EEZ) and continental shelf off the coast of Natuna Island overlaps China’s so-called "nine-dash line" claim. [...] Under international law, Indonesia is entitled to sovereign rights over its EEZ in the waters surrounding Natuna Island, and entitled to the resources in the area. If Indonesia agreed to a joint development proposal under SRMA, it would most likely lose its sovereign rights inside this EEZ because there would a "Resource Management Authority" to organise exploration of the joint development area. After a series of incidents with China in the North Natuna Sea in recent years, President Joko Widodo has strengthened Indonesia’s position in this area by focusing on three main programs: maritime tourism, energy and defence. Jakarta is better off focusing on developing the Natuna Islands on its own, rather than joining with China.
