China entered World War I not to fight, but to reclaim its lost territory.

In short: While China never sent combat troops to the Western Front, it played a pivotal role in the Great War. By deploying over 140,000 laborers to support the Allies, China hoped to secure a seat at the post-war negotiating table and finally reclaim sovereign control over the Shandong Peninsula from Japan.

At the outbreak of war in 1914, China declared neutrality, hoping to avoid the chaos of global conflict. However, Japan quickly seized German-held territories in Shandong, including Jiaozhou Bay and local railways. In 1915, Japan leveraged this position to issue the Twenty-one Demands, a secret ultimatum that sought to transform China into a Japanese dependency. President Yuan Shikai, struggling to maintain a wobbly republican state against internal warlords and political rivals, was forced to accept many of these humiliating concessions, which granted Japan extensive privileges in Manchuria and Shandong.

Denied the chance to fight directly—partly because Japan feared Chinese regional influence—China turned to a strategy of non-combatant support. Starting in late 1916, the Chinese Labour Corps began shipping thousands of volunteers, mostly from Shandong, to Britain, France, and Russia. These workers, often dismissed as mere coolies, performed the grueling labor of war: digging trenches, repairing tanks, and building munitions depots. Their contribution was not merely logistical; it was a calculated diplomatic maneuver. By becoming an Allied partner, Chinese leaders aimed to leverage their participation to cancel past indemnities and force the return of the Shandong Peninsula.

The path to formal belligerence was fraught with internal division. Premier Duan Qirui pushed for entry into the war to integrate China with Western powers, while President Li Yuanhong and others remained wary of Japanese ambitions. The turning point came in February 1917, when a German U-boat sank the French ship Athos, killing over 500 Chinese laborers. Following this tragedy and pressure from the United States, China officially declared war on Germany and Austria-Hungary on August 14, 1917. Although the nation’s military contribution remained minimal, the war fundamentally reshaped China’s political landscape, accelerating the rise of warlordism and setting the stage for the intense diplomatic struggles that would define the country’s future.
