Introduction
Background
The Spratly Islands consist of more than 100 small islands or reefs surrounded by rich fishing grounds - and potentially by gas and oil deposits. They are claimed in their entirety by China, Taiwan, and Vietnam, while portions are claimed by Malaysia and the Philippines. About 45 islands are occupied by relatively small numbers of military forces from 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.

Military and Security
Military - note
the Spratly Islands consist of more than 100 small islands or reefs of which about 45 are claimed and occupied by China, Malaysia, the Philippines, Taiwan, and Vietnam
China: occupies seven outposts (Fiery Cross, Mischief, Subi, Cuarteron, Gavin, Hughes, and Johnson reefs); the outposts on Fiery Cross, Mischief, and Subi include air bases with helipads and aircraft hangers, naval port facilities, surveillance radars, air defense and anti-ship missile sites, and other military infrastructure such as communications, barracks, maintenance facilities, and ammunition and fuel bunkers
Malaysia: occupies five outposts in the southern portion of the archipelago, closest to the Malaysian state of Sabah (Ardasier Reef, Eric Reef, Mariveles Reef, Shallow Reef, and Investigator Shoal); all the outposts have helicopter landing pads, while Shallow Reef also has an airstrip
Philippines: occupies nine features (Commodore Reef, Second Thomas Shoal, Flat Island, Loaita Cay, Loaita Island, Nanshan Island, Northeast Cay, Thitu Island, and West York Island); Thitu Island has an airstrip and a coast guard station
Taiwan: maintains a coast guard outpost with an airstrip on Itu Aba Island
Vietnam: occupies about 50 outposts in the Spratlys, plus some 14 platforms known as “economic, scientific, and technological service stations” (Dịch vụ-Khoa) that sit on underwater banks to the southeast that Vietnam does not consider part of the disputed island chain, although China and Taiwan disagree; Spratly Islands outposts are on Alison Reef, Amboyna Cay, Barque Canada Reef, Central Reef, Collins Reef, Cornwallis South Reef, Discovery Great Reef, East Reef, Grierson Reef, Ladd Reef, Landsdowne Reef, Namyit Island, Pearson Reef, Petley Reef, Sand Cay, Sin Cowe Island, South Reef, Southwest Cay, Spratly Island, Tennent Reef, West Reef; Spratly Island includes an airstrip with aircraft hangers; the underwater banks with stations include Vanguard, Rifleman, Prince of Wales, Prince Consort, Grainger, and Alexandra; over the past few years, Vietnam has continued to make improvements to its outposts, including defensive positions and infrastructure (2023)
Transnational Issues
Disputes - international
Taiwan-Brunei-China-Malaysia-Philippines-Vietnam: all of the Spratly Islands are claimed by China (including Taiwan) and Vietnam; parts of them are claimed by Brunei, Malaysia and the Philippines; despite no public territorial claim to Louisa Reef, Brunei implicitly lays claim by including it within the natural prolongation of its continental shelf and basis for a seabed median with Vietnam; the islands are strategically located in the South China Sea and are surrounded by rich fishing groups and potential oil and natural gas deposits; claimants in November 2002 signed the "Declaration on the Conduct of Parties in the South China Sea," which fell short of a legally binding "code of conduct"; in March 2005, the national oil companies of China, the Philippines, and Vietnam signed a joint accord to conduct marine seismic activities in the Spratly Islands; China’s island-building and military presence in the archipelago remain controversial
