ASEAN, China struggle to finalize South China Sea code amid rising maritime tensions
Tensions persist in the South China Sea as ASEAN nations and China negotiate a Code of Conduct to manage maritime disputes. Despite diplomatic talks, confrontations between Chinese and Philippine vessels have intensified in 2026, including water cannon incidents and vessel collisions. The 2016 international tribunal ruling rejected China's expansive nine-dash line claim, but Beijing has not accepted the verdict. A legally binding code was targeted for completion by July 2026 with the Philippines chairing ASEAN, but negotiations have stalled due to competing territorial claims within ASEAN itself, US-China strategic rivalry, and disagreements over military activities by external powers. Over three trillion dollars in annual maritime trade flows through these disputed waters. Analysts say further progress remains uncertain despite both sides expressing commitment to dialogue and de-escalation.

How different outlets framed it
Left-leaning coverage: Left-leaning outlets like Radio Free Asia highlight China's assertive maritime tactics, including water cannon use against Philippine vessels, militarization of disputed islands, and pressure tactics. They emphasize the 2016 international tribunal ruling against China and frame the Philippines' response as legally justified self-defense. These sources focus on human rights impacts, China's coercive 'gray-zone' tactics, and the importance of US-alliance support for regional stability.
Right-leaning coverage: Right-leaning coverage, including US-aligned military and defense sources, frames China as an expansionist threat conducting illegal militarization and rejecting international law. They emphasize the need for US military presence, freedom of navigation operations, and defense alliances like the Philippines-US Mutual Defense Treaty and AUKUS as necessary counterbalances to Chinese assertiveness.
