Southeast Asian diplomats are gathering in Manila this week to address a dual-front crisis: the escalating threat of a war between the United States and Iran and the persistent regional instability in Myanmar and the South China Sea. According to the Associated Press, the 11-nation Association of Southeast Asian Nations (ASEAN) will use these meetings to demand a return to dialogue in the Middle East, while simultaneously attempting to reconcile its own internal peace efforts with the reality of ongoing regional conflicts.
Middle East Hostilities and Global Energy Security
The primary concern for ASEAN members is the spillover effect of hostilities between the U.S. and Iran. According to two Southeast Asian diplomats, the bloc plans to issue a joint statement expressing alarm over the conflict, which has raised fears of renewed global supply and price shocks. The region, home to over 680 million people, remains highly dependent on Middle Eastern oil and gas. Disruptions in the Strait of Hormuz—a transit point for roughly 20% of global oil supplies—could have immediate domestic consequences. Philippine President Ferdinand Marcos Jr. previously declared a national energy emergency in March to manage fuel and food availability, a move that highlights the economic stakes for the host nation.

Roughly 20% of global oil supplies transit through the Strait of Hormuz. Any prolonged military conflict in the region directly threatens the energy stability of Southeast Asian economies.
The U.S.-China Dynamic in the Indo-Pacific
Secretary of State Marco Rubio and Chinese Foreign Minister Wang Yi. While Washington is currently preoccupied with the Middle East, the State Department maintains that its priority remains a “free and open Indo-Pacific,” according to spokesperson Thomas Pigott. Rubio has indicated openness to meeting with Wang, though he declined to comment on specific points of friction, such as election interference allegations. Meanwhile, the U.S. is expected to leverage its participation in the Quad—comprising the U.S., India, Japan, and Australia—to counter Chinese influence, a bloc Beijing has repeatedly criticized as a containment strategy.
Myanmar and the Limits of Regional Diplomacy
ASEAN faces significant internal pressure regarding the civil war in Myanmar. Since the 2021 coup, violence has resulted in at least 8,100 deaths and nearly 22,500 detentions, as reported by the Assistance Association for Political Prisoners. Despite a 2021 five-point peace plan, the military-backed government has failed to comply, leading ASEAN to ban Myanmar’s top leaders from high-level summits. Efforts to break the impasse, such as a recent meeting between Philippine Foreign Secretary Theresa Lazaro and Myanmar’s foreign minister in Bangkok, have drawn criticism. Rights groups argue that engaging with senior officials undermines the bloc’s own ban. Lazaro defended the move, stating, “The path to peace can only be obtained through resolute diplomacy with all parties to the conflict.”
South China Sea Territorial Negotiations
Negotiations regarding a “code of conduct” for the South China Sea remain a focal point for ASEAN and China. The proposed pact is intended to prevent territorial disputes from escalating into open conflict. The stakes are high: the region has seen a spike in confrontations between Chinese forces and the coast guards of the Philippines, Vietnam, Malaysia, and Brunei. While the ASEAN foreign ministers aim to stabilize these maritime encounters, the presence of major global powers at the table underscores the internationalized nature of these regional waters.
