A Public Confrontation in Seoul
Philippine Secretary of National Defense Gilberto Teodoro Jr. publicly challenged China’s maritime position during the Seoul Defense Dialogue on September 9, 2026, after a staffer mistakenly delivered a memo from a Chinese military attaché directly to him while he was onstage. The incident occurred as Teodoro was addressing the audience on the subject of “gray zone” coercion in the South China Sea, according to reporting from the Taipei Times.
Upon receiving the document, Teodoro read its contents aloud, which reiterated Beijing’s refusal to recognize the 2016 UN Convention on the Law of the Sea (UNCLOS) ruling that supports Philippine territorial claims. Teodoro immediately offered a line-by-line rebuttal to the note, characterizing the delivery as an attempt to influence his remarks. “This is not gray zone anymore,” Teodoro stated. “This is actual coercion, bullying and aggression.”
Escalating Diplomatic Tensions
The incident highlights the deepening rift between Manila and Beijing. Teodoro, a vocal critic of China’s presence in disputed waters, utilized the platform to call for “basic decency” in international relations. He further remarked in Filipino, “Have some shame,” drawing applause from the international delegation, which included defense ministers from South Korea and the Czech Republic. The Yonhap News Agency reported that the note was intended for internal distribution but was misdelivered by an event staffer who assumed it originated from the Philippine delegation.
In response, Chinese Ministry of Foreign Affairs spokeswoman Mao Ning urged Philippine officials to “stop clout-chasing” and “stop damaging China-Philippines relations.” China had previously imposed sanctions on Teodoro, citing his public rhetoric as a primary driver of bilateral tensions.
Regional Stakes and Security Commitments
Beyond the immediate exchange, Teodoro addressed concerns regarding the stability of US security commitments in the Indo-Pacific. Amid debates over US-South Korean military exercises, Teodoro confirmed that Washington has assured Manila that its defense commitments remain unchanged. He emphasized that bilateral and multilateral military cooperation involving the Philippines continues to expand, despite the evolving security landscape. The Defense Secretary concluded by stating he would keep the note as a “memento” of China’s desperation, signaling that Manila intends to maintain its assertive stance regarding its maritime rights.
