ASEAN and China struggle to finalize South China Sea code amid maritime tensions
The South China Sea remains a major flashpoint between China and Southeast Asian nations, with negotiations on a binding Code of Conduct stalled despite over two decades of talks. China claims nearly the entire sea through its nine-dash line, rejected by a 2016 international tribunal. Recent incidents in 2026 have escalated tensions, including collisions between Chinese and Philippine vessels near disputed shoals. The region handles roughly three point five trillion dollars in annual maritime trade. Key sticking points include whether any agreement will be legally binding, which areas it covers, and whether external powers like the United States should participate. ASEAN remains internally divided, with some members prioritizing sovereignty while others emphasize economic ties with Beijing. Diplomats continue talks, but hard power tactics—coast guard confrontations, military exercises, and artificial island building—increasingly dominate the dispute's trajectory.

How different outlets framed it
Left-leaning coverage: Left-leaning outlets highlight China's regional hegemony through military assertiveness, artificial island militarization, and coercive diplomacy against smaller nations. They underscore the 2016 international ruling against China's claims, criticize the use of coast guard harassment and water cannons against regional fishermen, and call for stronger ASEAN unity and US-Japan support to counter Beijing's dominance and protect international law.
Right-leaning coverage: Right-leaning outlets stress the importance of US-led alliances and freedom of navigation operations to counter Chinese territorial expansion. They emphasize the strategic threat China's military buildup poses to regional stability and American interests, support Philippine and allied assertiveness in defending their exclusive economic zones, and view the dispute through a great-power competition lens.
Limits of this briefing
Coverage skews toward English-language sources and Western outlets; Chinese state media perspectives are underrepresented. The dispute involves overlapping claims by multiple nations beyond just China and ASEAN, including Taiwan, and perspectives from smaller claimant states and non-claimant ASEAN members receive less attention.
