As July 7, 2026, marks the 89th anniversary of the Marco Polo Bridge Incident, the historical trauma of the Second Sino-Japanese War remains a potent instrument of political alignment in the Chinese world. Cheng Li-wun, a prominent political figure from Taiwan, has once again utilized the occasion to assert that the history of the 'July 7th Incident' must never be forgotten or altered. Her remarks, amplified by mainland Chinese state-affiliated media, underscore a strategic effort to find common ground between Beijing and certain factions in Taipei.
The incident in 1937 serves as the symbolic beginning of eight years of brutal conflict that redefined the modern Chinese state. For Beijing, the commemoration is not merely about honoring the past but about reinforcing a singular national narrative that links the mainland and Taiwan through a shared legacy of resistance against external aggression. By featuring a Taiwanese voice like Cheng's, the narrative shifts from a purely mainland concern to a 'Pan-Chinese' imperative, suggesting that historical loyalty should supersede current political divisions.
Cheng’s rhetoric specifically targets what many in the conservative 'Pan-Blue' camp see as a double-edged sword of revisionism. On one hand, it addresses the perceived whitewashing of wartime atrocities by conservative elements in Japan; on the other, it implicitly critiques the Democratic Progressive Party (DPP) in Taiwan for its efforts to 'de-Sinicize' Taiwanese education. This alignment of historical grievances creates a powerful, albeit contested, bridge across the Taiwan Strait that bypasses the formal political standoff.
In the broader geopolitical context, these anniversaries are increasingly used to pressure Japan, whose deepening security ties with the United States and Taiwan are viewed with suspicion by Beijing. The invocation of 1937 serves as a reminder of the consequences of Japanese militarism, aiming to mobilize public sentiment across the region. As the centennial of the incident approaches, the battle over historical memory is likely to intensify, serving as a barometer for the health of Cross-Strait relations and the volatility of Northeast Asian diplomacy.
