  Summit Dispute Contained

  The most likely outcome is that the accusation remains a diplomatic exchange rather than a broader rupture. ASEAN members have strong incentives to keep the summit agenda focused on trade, security cooperation, and regional unity, while Beijing and Manila preserve their claims without forcing a breakdown.

  Diplomatic Freeze Extends

  The summit dispute hardens into a short-term diplomatic freeze, with China limiting bilateral meetings and the Philippines appealing to ASEAN partners. This outcome is plausible because both governments face domestic incentives to avoid appearing weak on sovereignty.

  Maritime Tensions Rise

  The diplomatic dispute spills back into the South China Sea, where coast guard and militia encounters remain the highest-risk channel. A fresh incident would not necessarily imply war, but it would increase regional risk premiums and strengthen calls for U.S.-Philippine coordination.

  Crisis Management Improves

  A lower-probability but constructive outcome is that the dispute pushes ASEAN members to press harder for communication mechanisms. Beijing and Manila could still disagree on sovereignty while reopening operational channels to reduce accident risk.
