South China Sea Disputes explained: the key dynamics
Overlapping claims
China claims most of the South China Sea, overlapping with claims by the Philippines, Vietnam, Malaysia, Brunei, and Taiwan. The competing claims cover reefs, islands, and rich fishing and energy zones.
Militarization and incidents
China has built and militarized artificial islands, and confrontations between coast guards, militia vessels, and fishing fleets — especially involving the Philippines — recur at contested features.
Freedom of navigation
The sea carries a vast share of global trade, and outside powers conduct freedom-of-navigation operations, making the disputes a flashpoint in wider strategic competition.
Timeline: how the south china sea disputes unfolded
- 1947 — China publishes a map asserting expansive claims over the sea.
- 2014–16 — China builds and fortifies artificial islands at contested reefs.
- 2016 — An international tribunal rejects China's expansive claims; China rejects the ruling.
- 2023–26 — Confrontations, especially with the Philippines, keep tensions elevated.
How this conflict is mapped and tracked
Like Taiwan, the South China Sea is a dispute marked by standoffs and incidents rather than sustained armed conflict, so it is tracked through maritime confrontations, naval activity, and diplomacy rather than battle-death data. CFR and maritime monitors assess the incidents and escalation risk.
For how these datasets differ, see ACLED vs UCDP vs CFR and our guide to conflict-tracking tools.
Territorial Disputes in the South China Sea
The South China Sea — through which approximately $3 trillion in global trade transits annually — is subject to overlapping territorial claims by China, Vietnam, the Philippines, Malaysia, Brunei, and Taiwan. China's 'nine-dash line' claim encompasses roughly 90 percent of the South China Sea and has no recognized basis in international law; a 2016 Permanent Court of Arbitration ruling (which China rejects) found China's historical rights claims invalid.
China has constructed and militarized artificial islands in the Spratly and Paracel archipelagos, deploying anti-ship missiles, fighter jets, and naval facilities. Chinese Coast Guard and People's Armed Forces Maritime Militia (PAFMM) vessels regularly challenge Philippine resupply missions to Second Thomas Shoal, where the Philippines maintains a deliberate military presence on a grounded vessel. These confrontations have produced water cannon attacks and collisions.
The Philippines, under President Ferdinand Marcos Jr., has deepened its security alliance with the United States. Expanded basing access under the Enhanced Defense Cooperation Agreement (EDCA) enables greater U.S. rotational presence. Vietnam, Malaysia, and Indonesia have also quietly strengthened their defenses. The risk of a kinetic incident — a collision resulting in casualties, or a Philippine decision to respond militarily to a Chinese interdiction — is assessed as elevated.
