A Chinese Note Turned Seoul’s Forum Into a Stage

Philippine Defense Secretary Gilberto Teodoro read a Chinese embassy note aloud at the Seoul Defense Dialogue on Sept. 8, then called the delivery bullying. He was on a live panel with South Korea’s defense minister when a staffer set the paper on his table.

The slip restated Beijing’s rejection of the 2016 South China Sea ruling. Teodoro named the Republic of Korea as the party being disrespected, and he left the host ministry with a scene it has not explained.

The Note That Reached the Panel Table

The moment came in Plenary Session 1 at the Grand Lotte Seoul, during a discussion billed as a search for a more stable international order. Teodoro was answering a question about gray-zone pressure in the South China Sea, the kind of force that stops short of open war, when a man in a light coat walked up from behind and put a sheet of paper beside him.

“I have a note here, I think this is from China,” Teodoro said. He asked if he should read it, then did. Forum organizers later said the text came from a Chinese military attache at the embassy in Seoul, who handed it to a staff member and asked that it be given to the secretary. The staffer, they said, took it for a message from Teodoro’s own delegation and walked it onto the stage while he was still speaking.

WHAT THE ROOM CAN SEE

• On camera: A staffer places a sheet of paper on Teodoro’s table during a live panel beside South Korean Defense Minister Ahn Gyu-back and Czech Deputy Prime Minister Jaromir Zuna.
• Organizers’ account: A military attache at China’s embassy in Seoul asked staff to pass the note; the staffer mistook it for a Philippine delegation message.
• The paper’s first lines: China’s position on the South China Sea arbitration is “clear, consistent and firm,” the arbitration “violates fundamental principles of international law,” and the “so-called award” is “illegal, null and void” with “no binding force.”

WHAT SEOUL HAS NOT SETTLED

• Intent: Whether the attache meant the paper to arrive mid-answer, in front of the room, has not been stated in public by the embassy or the host ministry.
• The host’s version: South Korea’s Ministry of National Defense has not described how a foreign embassy note reached a live ministerial table.
• The unread close: The Department of National Defense later posted the handwritten sheet; a second paragraph Teodoro did not read said China would handle maritime disputes through dialogue and consultation.

A legal reservation at a ministerial forum already has a protocol. A paper drop onto a live table is not that protocol. The sentences on the slip have been Beijing’s public line since 2016. The courier method is what made them news, and it dumped a bilateral fight into a hall Korea had rented for something else.

Teodoro Answered It Line by Line

He did not set the paper aside. He treated each clause as a prompt and answered it in front of the same audience the attache had tried to reach through a staffer.

THE RETORTS ON THE FLOOR

• On “violates international law”: “So what you signed, UNCLOS, violates international law? That’s what you mean.”
• On “illegal, null and void”: “So say you.”
• On “no binding force”: “Because you don’t want to be subjected to UNCLOS.”
• On refusing the award: “Of course, because you lost.”

He held the slip up and asked how anyone deals civilly with a country that, in an international forum, disrespects the organizers and then tries to correct a minister while a question is still on the floor. He said the act threw the U.N. Convention on the Law of the Sea on the floor and trampled it, and that it also failed “the basic decency that should be accorded to our most gracious host, the Republic of Korea, and the rest of the audience here.”

This is not a gray zone anymore. This is actual coercion, bullying, and aggression. I will keep this paper as a memento of how desperate China is and how ineffective its position is in the face of a free audience.

He thanked the person who had handed him the paper for doing China “a great service,” and added that he hoped they would not “suffer in a gulag for it.” The room applauded. The legal argument in the note had not moved an inch. The host now owned the footage.

What the 2016 Award Still Binds

The paper was not a new claim. It was a short restatement of the position China has held since a five-member tribunal, with the Permanent Court of Arbitration as registry in PCA Case 2013-19, issued its award on July 12, 2016. The Philippines filed the case against China in 2013 under UNCLOS after talks failed. China refused to take part. The tribunal sat anyway.

The Philippine National Security Council still posts the findings as the country’s legal baseline, including that the nine-dash line has no legal effect. UNCLOS, the council notes, now has 171 states as parties. The award is final and not subject to appeal under Article 296 of the treaty and Article 11 of Annex VII. A party’s refusal to show up does not cancel the result.

THE AWARD VERSUS THE SEOUL NOTE

Teodoro used that last gap on the floor. If China signed UNCLOS and then calls the ruling a violation of international law, he said, the complaint is aimed at the treaty itself. The note’s unread close, about dialogue, is the line Beijing prefers when the cameras are off. The first paragraph is the line it sends when it wants a minister to stop talking.

Seoul Built a Forum for Coexistence

The 15th Seoul Defense Dialogue ran Sept. 7 to Sept. 9 under the Ministry of National Defense. The official site sells the gathering as a search for new pathways toward coexistence “in the age of Turbulence.” Teodoro was listed as a plenary speaker with Ahn and Zuna. Uganda’s Kiryowa Kiwanuka and Papua New Guinea’s Elias Kapavore were on the same roster. The opening talk from Seoul was about the Korean Peninsula, not the West Philippine Sea.

THE THREE DAYS IN SEOUL

1. Sept. 7, 2026: The forum opens at the Grand Lotte Seoul. Teodoro meets Ahn on the sidelines to talk defense cooperation, the same day he warns that cuts to U.S.-South Korea drills could give China an opening in the wider Indo-Pacific.
2. Sept. 8, 2026: Plenary Session 1. A staffer delivers the attache’s note while Teodoro is on the mic. He reads it, names Korea as the disrespected host, and calls the act coercion.
3. Sept. 9, 2026: China’s foreign ministry answers. South Korea’s defense ministry still has not described the chain of custody for the paper.

That calendar is the part the viral clip leaves out. Seoul spent the same plenary talking about talks with North Korea. Ahn said he hoped a meeting between U.S. President Donald Trump and Kim Jong Un could still happen, and that the South Korean military would back diplomacy with force on standby. A Chinese embassy note about an old maritime case was not on that agenda. It arrived anyway, through Korean staff, in a Korean ballroom, next to the Korean minister.

Teodoro had already put Korea in the story before the paper landed. He told the room that Manila faces daily attempts by China to occupy and assert itself in Philippine waters and in the exclusive economic zone, and that no state has a right to take an international common for exclusive use. Then the note gave him a prop. He used it to say the insult ran to the host, not only to him.

Beijing Calls the Reading Grandstanding

China’s foreign ministry spokeswoman Mao Ning took the question on Sept. 9. She said she was not aware of the specifics on the ground. She did not confirm the attache. She did not discuss the staffer. She aimed at the man who had read the paper.

We urge certain individuals in the Philippines to stop grandstanding and stirring up trouble, and to cease undermining China-Philippines relations and stability in the South China Sea.

That is the inversion the clip produced. Beijing’s position on the 2016 award did not change. The method of delivery became the story, Teodoro made the method the offense, and the ministry in Beijing treated the public reading as the provocation. The unread second paragraph, about dialogue, never made the soundtrack. The first paragraph did, because a minister recited it into a microphone.

The Chinese Embassy in Seoul has not put out its own account of who wrote the slip or why it had to arrive during an answer. Until it does, the organizers’ version is the only institutional description of the chain: attache, to staff, to table, to a free audience.

The Tagalog Line Was for Manila

After the English dressing-down, Teodoro switched. “Maging disente lang kayo ng konti, mahiya naman kayo ng konti,” he said. Be a little decent. Have a little shame. The Department of National Defense cut the video with the shorter caption “MAHIYA NAMAN KAYO” and the tag #DiKaPasisiil, a line that says the country will not be cowed. It posted the clip the same day.

The Tagalog is not a flourish for the Czech minister. It is the same rebuke President Ferdinand Marcos Jr. has used at home, now spoken from a Korean stage and shipped back on an official account. The legal fight in the South China Sea is a daily operational grind. The clip is a domestic product as much as a diplomatic one. It tells a Filipino audience that the defense secretary will not swallow a note in silence, even when the note arrives in someone else’s capital.

That choice has a cost for the host. A forum that wanted coexistence now lives online as the room where a Chinese embassy paper met a Filipino punch line. Seoul did not write either half of that exchange. Its staff carried the first half. Its livestream carried the second.

Why the Host Has Not Spoken

South Korea’s defense ministry organized the dialogue, staffed the floor, and ran the video feed. It has not issued a public account of the attache, the staffer, or Teodoro’s charge that the act disrespected the Republic of Korea. Silence keeps Seoul off the PH-China argument on paper. It also leaves the organizers’ leak to local reporters as the only official-adjacent version of how a foreign embassy used Korean hands to reach a live mic.

Teodoro said he would keep the sheet as a memento. The more durable copy is the one the host cannot pull back: a three-day coexistence forum, a staffer in a light coat, a minister who read the paper, and a foreign ministry in Beijing that called the reading the problem. Seoul still has not said who, in its own hall, was supposed to stop the note before it hit the table.
