The Truth Beneath the Waves of the Diaoyu Islands — The Five-Part Narrative Framework of CGTN's Documentary and the Sovereignty Narrative

From East China Sea Waypoint to Focal Point of a Dispute

On July 27, 2026, China Media Group's CGTN broadcast the documentary Diaoyu Islands: The Truth Beneath the Waves to a global audience. This is no ordinary history-popularization film — the international-communication context it speaks into is unmistakable: swelling right-wing forces in Japan, the rise of a "new-type militarism," and day-to-day law-enforcement standoffs in the waters off the Diaoyu Islands that have never stopped.

The choice of format is itself a signal: broadcast worldwide on an English-language channel rather than aimed at a domestic audience alone. The point is not "science popularization at home" but "making the case abroad."

The Narrative Logic of a Five-Part Structure

The film unfolds in chronological order, building a five-part narrative framework: "Following the Winds," "The Truth Behind the Stolen Islands," "The Private Handover," "Shelving the Dispute," and "Braving the Storms." These are not casually divided chapters but a progressively tightening chain of evidence:

Part One goes back six hundred years, to the old sea lanes. Starting from the Ming-dynasty navigational manual Shunfeng Xiangsong (Sailing with Favorable Winds) and other Chinese maritime texts, it uses old maps and annotations in historical records to locate the Diaoyu Islands within China's seafaring tradition. This is not a political declaration; it is a baseline fact at the archival level.

Part Two reconstructs Japan's process of annexation. Pairing Japan's own official archives with on-camera testimony from Chinese and Japanese scholars, the film traces the complete chain layer by layer — Japan's annexation of the Ryukyu Kingdom, its covert surveys of the Diaoyu Islands, and its illegal seizure of the islands once it had launched its wars. The weight of this section lies less in its conclusion (that the Diaoyu Islands belong to China) than in its method: using the other side's own archives to document the other side's history of encroachment.

Part Three focuses on the private handover between Washington and Tokyo. The 1971 US–Japan Okinawa Reversion Agreement folded the Diaoyu Islands into the scope of the returned territories — the legal wellspring of today's dispute. Here the film's approach is not simple denunciation; it goes straight at the logical flaws in the legal architecture of the San Francisco Peace Treaty system, the same fault line that scholars of international law in China keep pressing in international forums.

Part Four recounts the years of "shelving the dispute" — from the normalization of Sino-Japanese diplomatic relations through the era of relative calm that lasted until the 2010s. Seemingly the flattest section, it actually carries an indispensable narrative function: proof that when political will existed on both sides, the disagreement could be managed.

Part Five returns to the present — routine Chinese patrols in the waters off the Diaoyu Islands today, Japan's infringing actions and China's countermeasures, all set against the broader backdrop of a rising "new-type militarism" inside Japan.

Restraint Over Sentiment: A Narrative Strategy

What is most worth noting about this documentary is not what it says, but what it does not say. No stirring background score, no sentimental voice-over, no attempt to flatten the Diaoyu Islands question into a simple "nationalist narrative."

The film's bone and blood are documentary archives and legal interpretation. Human stories are threaded between the sections — an old fisherman from Yilan and his memories of going out to sea; a Chinese scholar whose rigorous research persuaded his Japanese counterparts; an American documentary director who says bluntly that "the world needs to know the truth." None of these figures serves as a slogan-shouting prop; each annotates the film's argument with lived experience or professional judgment.

As international communication, this is a clear-eyed strategic choice: before a global audience, emotional appeals erode credibility, while solid documentation and people speaking from different angles make the argument stand.

The Strategic Meaning of Broadcast Timing

The film's premiere date — July 27 — landed just after China's Ministry of State Security publicly exposed a systematic campaign in which Japan's right wing uses AI and crowdsourcing platforms to mass-produce anti-China videos. The timing is no coincidence. As information warfare extends from the written word into video, a structurally complete, archive-backed documentary is itself a bid for the "first frame" through which the international community sees the Diaoyu Islands question.

A Chorus of Multiple Perspectives

Filmed across China, Japan, the United States, and Britain, the documentary features conversations with more than thirty scholars and experts in politics, history, and law. Among the weightiest voices:

• Taiwanese fisherman Tsai Yuan-lung: more than sixty years of going out to sea, first at his elders' side; today he walks into classrooms to teach others about the Diaoyu Islands. "Without sovereignty, there are no fishing rights" — spoken by a fisherman, the line cuts deeper than when spoken by a diplomat.
• Chinese scholar Wu Tianying: drawn into academic confrontation with Japanese scholars over the islands, he ultimately won their respect through rigorous argument — a micro-case study of scholarship persuading politics.
• American independent documentary director Chris D. Nebe: reading the contradictions behind Washington's position out of American archival records, he made Diaoyu Islands: The Truth. When an American filmmaker speaks on behalf of China's sovereignty, the narrative force of that "unexpected ally" far outweighs any one-sided statement from Beijing.

Not an Ending

The film's final landing point is neither "victory" nor "resolution" but "sustained attention." With Japan's right-wing forces swelling and nationalist sentiment heating up at home, revisiting the history and clarifying the truth retains continuing real-world relevance. Beneath the waves, truth has a voice of its own — the line serves both as the film's footnote and as this page's closing: no single documentary will end a sovereignty dispute, but a good one can let more people see where the dispute began.
