Spratly Islands

The Spratly Islands consist of more than 100 small islands or reefs surrounded by rich fishing grounds -- and potentially by gas and oil deposits. China, Taiwan, and Vietnam all claim the islands in their entirety, while portions are claimed by Malaysia and the Philippines. Around 70 disputed islets and reefs in the Spratly Islands are occupied by China, Malaysia, the Philippines, Taiwan, and Vietnam. Since 1985, Brunei has claimed a continental shelf that overlaps a southern reef but has not made any formal claim to the reef. Brunei claims an exclusive economic zone over this area.
