Shenyang Marks 95th Anniversary of 1931 Mukden Incident

The northeastern Chinese city of Shenyang on Friday held its annual “Never Forget September 18” bell-tolling and air-raid siren ceremony, marking the 95th anniversary of the 1931 Mukden Incident — the event that China regards as the opening of Japan’s invasion and the start of its 14-year War of Resistance.

The ceremony took place on the morning of September 18 at the broken-calendar stele square outside the Shenyang “September 18” History Museum in Liaoning Province, Xinhua reported. Fourteen representatives from across society tolled the “Warning Bell” 14 times, symbolizing the 14 years of resistance from 1931 to 1945, before a three-minute citywide air-raid siren sounded at 9:18 a.m. while trains, ships and vehicles sounded their horns and pedestrians stood in silence.

A False-Flag Beginning

The Mukden Incident — known in China as the September 18 Incident — began on the night of September 18, 1931, when officers of Japan’s Kwantung Army detonated explosives on the South Manchuria Railway near Liutiaohu, north of Shenyang, and blamed the blast on Chinese forces. As Xinhua recounted, the Japanese army then shelled the Chinese garrison at Beidaying. Shenyang fell overnight; the rest of the Northeast was occupied within months.

The 2026 report described the sequence in stark terms: “Overnight, Shenyang fell. Within months, the Northeast fell. Within a few years, more than half of China was under the Japanese invaders’ iron heel.”

The League of Nations’ Lytton Commission concluded in October 1932 that Japan’s action was aggression and that China held sovereignty over the Northeast; the League formally demanded a Japanese withdrawal in 1933. The Tokyo Trial judgment later recorded that “Japan’s invasion of China began on the night of September 18, 1931.”

A Tradition Since 1995

Shenyang has sounded the September 18 air-raid siren annually since 1995. The ritual has since spread, with many Chinese cities now testing their sirens on the date. As the Chinese military’s PLA Daily described in its account of a previous year’s ceremony, the 14 bell tolls “warn people never to forget the arduous course of the Chinese nation’s 14-year War of Resistance.”

Veteran Li Weibo, who has attended the ceremony for many years, told PLA Daily: “The country is stronger and the people’s army more powerful, but the bloody lesson must not be forgotten; we must take history as a mirror and stay vigilant in peacetime.”

A Sharper Anti-Japan Message in 2026

This year’s coverage carried a notably sharper geopolitical edge than in prior anniversaries. Xinhua’s report warned that Japan is accelerating what it calls “re-militarization” and that a country which has “not truly reflected on its historical guilt” being re-armed into a “war-capable” state could allow “historical tragedy to repeat itself.”

In a September 17 commentary, Xinhua international affairs observer Zhou Yaxin wrote that commemorating the date “is not to perpetuate hatred, but to restore historical truth and better cherish peace and open up the future.” Zhou described the incident as “a mirror” reflecting Japanese militarism’s “manipulation of public opinion, aggression, self-justification and historical revisionism,” and “a line of defense” urging the world to uphold the post-war international order.

The Chinese Ministry of National Defense also published a commemorative poster on its 国防部发布 WeChat account, carried by Guancha: “Now, 95 years on, the smoke of war has cleared, the land has revived, the world has changed. But we must not forget the sacrifices of our forebears, nor the suffering of our nation.”

China Daily struck a similar note, arguing that the anniversary should be remembered “not to perpetuate hatred, but to safeguard peace.”

Why the Rhetoric Has Hardened

The hardening tone reflects a broader deterioration in China-Japan relations. Chinese state media have repeatedly accused Tokyo of “re-militarization,” framing it as a “gray rhino” threat. Just a day before the anniversary, Japanese Prime Minister Takaichi Sanae reshuffled her cabinet, bringing the right-wing Japan Innovation Party into government — a move presented in Chinese commentary as evidence of a rightward shift.

For Beijing, linking the 1931 invasion to present-day security policy is a way of anchoring a contemporary strategic argument in an unimpeachable historical grievance. The message is aimed both domestically, as patriotic education, and outward, as a warning to Tokyo and its partners.

The anniversary also retains deep domestic resonance. Previous observances have drawn about 1,000 attendees and featured student recitations honoring resistance leaders such as Yang Jingyu, Zhao Shangzhi and Zhao Yiman, who led guerrilla warfare in the Northeast. The fighting came at a staggering cost: more than 35 million Chinese military and civilian casualties over the 14 years of war.

What to Watch

Friday’s ceremony was, in form, identical to those of recent years — the same 14 tolls, the same three-minute siren, the same silent standstill. What has changed is the framing around it: a commemoration that once served chiefly as an act of remembrance is now also a platform for signaling China’s concerns about Japan’s military trajectory.

Whether that sharper messaging escalates further will depend largely on the trajectory of China-Japan relations in the months ahead — and on how Tokyo responds to an anniversary that Beijing clearly intends the world to keep watching.
