U.S. Secretary of State Marco Rubio convened with Chinese Foreign Minister Wang Yi during the ASEAN foreign ministers’ summit in Manila on Wednesday to address escalating bilateral tensions ahead of a planned summit between Presidents Joe Biden and Xi Jinping in September. The discussions highlighted divergent positions on South China Sea disputes, Iran policy, and mutual commitments to managing disagreements constructively.
Amid mounting geopolitical friction, both nations emphasized the urgency of stabilizing relations to ensure a productive Biden-Xi meeting. ASEAN members voiced concerns over China’s territorial claims and U.S.-led naval presence in the South China Sea, as well as Washington’s sanctions-driven pressure on Iran. These issues dominated the three-day ASEAN dialogue, with Tokyo and Jakarta particularly vocal about regional security implications.
Rubio reiterated U.S. adherence to defense obligations to the Philippines following a recent Chinese-Philiptine naval incident at Second Thomas Shoal, where a Philippine sailor sustained injuries during a Chinese Coast Guard confrontation. “We intend to uphold our treaty commitments,” Rubio stated, echoing a Philippine op-ed he authored warning that regional stability could collapse if Beijing weaponizes trade and infrastructure control. China maintained its stance on sovereignty claims while endorsing “pragmatic, positive” dialogue.
The U.S. has bolstered Philippine maritime capabilities, pledging $100 million in security aid for 2026 alongside a $9 million jetty expansion for enhanced Coast Guard operations. This follows heightened military aid to regional partners amid China’s expansive naval assertiveness.
In Iran remarks, Rubio condemned Tehran’s “lack of seriousness” regarding nuclear negotiations, asserting Washington’s resolve to protect strategic interests through airstrikes on infrastructure. He signaled potential engagement with Russian Foreign Minister Sergei Lavrov to explore conflict resolution pathways for Ukraine, framing transatlantic-Russia dialogue as contingent on partner diplomacy.
