evidence: For the non-territorial claimants, the story is even more confusing. For example, Indonesia has an undisputed claim to the Natuna Islands in the southwest part of the South China Sea. These populous islands rate an EEZ, which easily projects into the area enclosed by the U-shaped line yet does not come within 200nm of any Spratly feature. If China intends to translate its claim to "maritime rights and interests" in this area into a legal claim sovereign rights and jurisdiction, Indonesia will further intensify its domestic campaign to build capacity to effectively administer and control its UNCLOS-defined zones. Growing friction between Chinese and Indonesian MLE vessels and fishermen in this area is the product of as-yet unaccountable Chinese exercises of maritime rights.[10]
