South China Sea Consensus: No ASEAN Chair Can Move It

The Philippines entered its 2026 ASEAN chairmanship with a strong hand on the South China Sea issue, holding the pen on the communique and having bolstered domestic legal infrastructure and secured bilateral partner commitments. However, the joint communique adopted at the ASEAN Foreign Ministers' Meeting (AMM) was functionally identical to the one drafted during Malaysia's chairmanship the previous year, particularly concerning the South China Sea. A full decade after the arbitral ruling, it remains absent from ASEAN's consensus language. This outcome points less to the Philippines' diplomatic prowess and more to a constraint embedded within ASEAN's consensus mechanism itself. The Philippines had been active institutionally, endorsing the ASEAN Maritime Centre to be hosted by the Philippines, finalizing the institutional framework for the ASEAN Coast Guard Forum, and establishing a dedicated maritime law unit within its Department of Justice. Bilaterally, it secured commitments such as approximately $18 million in drone support and civil maritime assistance from Australia, and saw European countries accede to the Treaty of Amity and Cooperation (TAC). Turkey was also admitted as ASEAN's 12th dialogue partner. Yet, on the 10th anniversary of the arbitral ruling on July 12, fourteen countries reaffirmed its finality and binding nature in a joint statement, but only the Philippines from ASEAN signed it. Following a clash between Philippine and Chinese vessels at the Second Thomas Shoal on July 20, no ASEAN member stood with the Philippines. External coalitions are demonstrating a willingness to go further than the organization itself. The South China Sea paragraphs in the communique confirm this pattern. Comparing the 2025 and 2026 texts, the language is nearly identical, carrying over phrases like "concerns expressed by some Ministers" and maintaining unchanged passages on self-restraint, non-militarization, and confidence-building. The arbitral ruling is not mentioned. A notable shift, however, occurred regarding the Code of Conduct (COC). While the 2025 communique called for "early conclusion," the 2026 text softened this to "continued efforts in endeavoring to conclude" within the year, despite the fundamental obstacles regarding its legal bindingness and relation to the 2002 Declaration remaining unresolved. The most distinctive language in the communique pertained not to the South China Sea, but to the "restoration of the safe, unimpeded and continuous transit passage of vessels and aircraft in the Strait of Hormuz." This suggests that escalating events in the Persian Gulf have captured ASEAN's attention more strongly than the South China Sea issue. While ASEAN's consensus and non-interference principles are crucial for bloc cohesion, they become a constraint in high-stakes territorial disputes like the South China Sea. Moving the communique's language would necessitate collective acceptance that the institution can take sides, a redefinition beyond the scope of a single chairmanship. Furthermore, survey findings indicating favorable views of China exceeding those of the United States, coupled with new US tariffs, are accelerating regional hedging strategies among ASEAN members, narrowing the space for collective positions. The Philippines is responding by building domestic and bilateral institutional capacity to sustain its maritime claims, regardless of whether ASEAN consensus follows. Whether this infrastructure endures beyond its chairmanship year remains to be seen. Source: Asia Times Vietnam
