Trump Tells Marcos He'll Raise Philippines' South China Sea Concerns With Xi

President Trump told Philippine President Ferdinand Marcos Jr. in a phone call Thursday evening that he'll raise Manila's concerns about the South China Sea when he sits down with Chinese President Xi Jinping later this year, according to a statement from the Philippine president's communications office.

The two leaders discussed "the current global, economic and security situation," the Presidential Communications Office said. Trump "assured President Marcos that he would take up the concerns of the Philippines in his next meeting" with Xi, the statement said. The White House did not immediately respond to a request for further details, according to Bloomberg.

Trump is expected to meet Xi in the United States around September 24 as Washington and Beijing try to stabilize a relationship strained by tariffs, tech restrictions, and military posturing in the Pacific.

Why This Call Happened Now

The timing isn't random. Violence broke out on July 20 when China Coast Guard personnel approached the grounded BRP Sierra Madre, the rusting warship the Philippines uses as a military outpost on Ayungin Shoal (also called Second Thomas Shoal), according to Philstar.com. A Filipino sailor was struck in the head with a baton and injured by a CCG member during the confrontation.

That incident happened three days before Trump's call with Marcos, and one day after Marcos personally briefed Secretary of State Marco Rubio on it at Malacañang Palace. Rubio was in Manila for the ASEAN Post-Ministerial Conference, according to Philstar.com. The Marcos-Trump call was, in the Philippine government's own framing, a direct follow-up to that Rubio meeting.

Malacañang also said Marcos wants a "reset" of relations with Beijing, according to Philstar.com, and does not want a repeat of the Ayungin Shoal confrontation. That's a notable data point. Manila isn't just looking for American backup, it's signaling it wants to de-escalate with China directly, not just lean on Washington to fight its battles.

The Treaty Obligation Question

The United States is a mutual defense treaty ally of the Philippines. That treaty commitment is exactly why this phone call matters beyond diplomatic small talk. Every time Chinese vessels ram, block, or use water cannons and batons against Philippine ships or personnel in disputed waters, Washington faces pressure to clarify what triggers its defense obligations.

Trump agreeing to "take up" Manila's concerns with Xi is a modest, low-cost diplomatic gesture. It commits the U.S. to raising the issue in conversation. It does not commit the U.S. to any specific action, sanction, or military response if China continues these incidents. That distinction matters and neither the Bloomberg-sourced reports nor the Philippine government statement claim otherwise.

A reasonable skeptic in Manila could point out that the Philippines has heard reassurances from Washington before, across multiple administrations, while Chinese coast guard activity in the South China Sea has continued largely unabated. Raising a concern in a leaders' meeting is not the same as changing Beijing's behavior on the water. That's a fair, evidence-based reservation given the pattern of prior incidents at Ayungin Shoal and Scarborough Shoal in recent years.

At the same time, the alternative, saying nothing to Xi at all, would be read in Manila as Washington deprioritizing a treaty ally right after one of its sailors was injured. Trump's commitment, however modest, is the baseline diplomatic move a treaty ally would expect.

What's Actually at Stake in September

The Trump-Xi meeting, expected around September 24, is fundamentally about the broader U.S.-China economic and security relationship, not the Philippines specifically. Tariffs, technology export controls, and Taiwan will almost certainly dominate that agenda.

The South China Sea dispute risks becoming what Bloomberg's reporting calls a genuine source of friction between the two superpowers, precisely because Washington and Manila's treaty relationship doesn't disappear just because Trump and Xi are trying to stabilize broader ties. China claims nearly the entire South China Sea under its "nine-dash line," a claim an international tribunal in The Hague rejected in 2016 in a case brought by the Philippines. Beijing has never recognized that ruling.

None of the three available accounts, from Bloomberg (via ArcaMax and The Star), or Philstar.com, indicate the White House has confirmed the call's contents beyond the Philippine government's own statement. Everything reported here about what Trump actually said comes from Manila's characterization, not a White House readout.

The open question is what, specifically, Trump will say to Xi come September, and whether Beijing changes any behavior in the Ayungin Shoal area between now and then. Nothing in the current reporting suggests China has agreed to anything. The injured Filipino sailor's condition and any Philippine response to the July 20 incident remain separate threads Manila is handling on its own, independent of whatever Trump raises with Xi.
