The Seoul Defense Dialogue Confrontation
On September 8, 2026, Philippine Defense Secretary Gilberto Teodoro Jr. was a panelist at the Seoul Defense Dialogue in Jung District, central Seoul. Mid-speech a handwritten note was passed to him; the document restated Beijing’s rejection of the 2016 Permanent Court of Arbitration award that favored Manila and declared the ruling “illegal, null and void.” Teodoro read the note aloud, labeling China’s conduct in the South China Sea as “coercion, bullying and aggression” and accusing Beijing of violating the United Nations Convention on the Law of the Sea (UNCLOS). The episode drew applause from the audience and was widely shared on Philippine social media.
Background to the Dispute
The 2016 arbitration, brought by the Philippines under UNCLOS, ruled that China’s “nine-dash line” claim has no legal basis and affirmed the Philippines’ exclusive economic zone (Exclusive Economic Zone (EEZ)) in the contested waters. China has consistently rejected the award, maintaining its maritime claims and continuing coast-guard operations near features such as Scarborough Shoal. In June 11, China announced sanctions against Teodoro, barring him, his spouse and child from entering mainland China, Hong Kong and Macau, citing “irresponsible remarks.” On July 12, the Philippines joined the United States, Japan and eleven other nations in a statement reaffirming that China’s expansive claims lack legal foundation.
Official Statements & Responses
Philippine Coast Guard spokesman Jay Tarriela called the incident “evidence of China’s bullying” and urged the international community to condemn Beijing’s conduct in the South China Sea.
Conflicting Reports & Gaps
Sources differ on the note’s origin. The Straits Times describes the note as coming from the “Chinese Embassy’s defense attaché” and notes that a forum staffer delivered it to Teodoro. Mao Ning’s later comment that she was “not sure what exactly happened” adds further ambiguity, and the Chinese foreign ministry has not issued a formal rebuttal beyond the general urging to cease “provocations.”
