Who He Is
Gilberto Eduardo Gerardo Cojuangco Teodoro Jr. — nicknamed “Gibo” — is the 23rd Secretary of National Defense, serving under President Bongbong Marcos since June 2023. He previously held the same post from 2007 to 2009 under Gloria Macapagal Arroyo, and was Arroyo’s Lakas–Kampi presidential nominee in 2010, losing to his second cousin Benigno Aquino III.
A De La Salle commerce grad, UP law summa cum laude, 1989 Bar topnotcher, and Harvard LLM, Teodoro is the classic technocrat — practiced lawyer, former three-term Tarlac representative, and NDCC chairman during Typhoon Ketsana.
The Note That Sparked a Firestorm
Mid-panel at the Seoul Defense Dialogue 2026 on Sept 8, a Chinese delegate handed Teodoro a note referencing Beijing’s stance on the landmark 2016 Arbitral Award. Instead of ignoring it, Teodoro read it aloud and went on a tangent — calling the gesture “disrespecting” and telling the Chinese side to try “basic decency.”
The outburst, captured on video and shared widely, turned a routine multilateral forum into a Philippines-China showdown on the world stage.
What He Actually Said
Teodoro framed the note as proof of Chinese arrogance, telling the audience that Manila won’t be intimidated by back-channel provocations. He doubled down on the rules-based order argument, insisting the 2016 PCA ruling is final and non-negotiable — and that Beijing’s continued territorial claims in the South China Sea violate international law.
The Bigger Picture
The Seoul incident comes hot on the heels of Teodoro warning that China could exploit defense gaps from cuts in US-South Korean exercises. He pressed Seoul and Washington to maintain joint drill tempo, arguing that any reduction signals weakness Beijing will rush to fill.
Also on the Seoul sidelines: HD Hyundai Chairman Chung Ki-sun met Teodoro to discuss expanding Philippine Navy modernization cooperation, underscoring the defense ties Manila is deepening while tensions with Beijing rise.
Key Takeaways
- Background: 23rd Defense Secretary (2nd stint); former rep, 2010 presidential candidate, Harvard LLM, Bar topnotcher
- Note incident: Chinese delegate handed Teodoro a note on the 2016 Arbitral Award during a panel — Teodoro read it and slammed Beijing

What’s Next
Watch for Manila’s formal response to Beijing and whether the South China Sea tension escalates further. The 2016 ruling remains the legal anchor — but Beijing has never accepted it, and Teodoro’s firebrand style suggests he’s done waiting for diplomacy to work.
