Two Japanese workers were injured when a chemical agent leaked from a shell during a recovery operation in Jilin Province, China [1].

The incident highlights the persistent dangers of abandoned munitions from the Imperial Japanese Army and the complexities of joint recovery efforts between Tokyo and Beijing.

The workers were part of a sanctioned excavation team tasked with locating and removing chemical weapons left behind by the Japanese military [1]. A Cabinet Office source said the injuries occurred when a shell ruptured, releasing a chemical agent that caused contact injuries to the staff [1].

Reports indicate the incident took place on May 26 [1]. While some sources suggest a date in April, the recovery team's reports identify the 26th of the month preceding the June report [1].

Both individuals were wearing protective suits at the time of the leak [1]. They were transported to a local hospital in the Heilongjiang-border region for observation [1]. After spending several days under medical supervision, the workers returned to Japan [1].

China has previously signaled a desire to expedite the removal of these hazardous materials. Guo Jiakun, a spokesperson for China’s Foreign Ministry, said on April 30, 2024, "We are accelerating the disposal of the abandoned chemical weapons left by the Japanese army" [2].

The recovery operation is part of a long-term effort to clear contaminated sites in China to prevent civilian casualties, and environmental damage. The use of specialized Japanese teams is intended to ensure the safe handling of unstable munitions, though this leak demonstrates that the process remains high-risk [1].

The rupture of a chemical shell during a sanctioned recovery operation underscores the volatility of century-old munitions. Despite the use of protective equipment and expert teams, the physical degradation of these weapons poses a continuous risk to personnel. This incident may increase pressure on both governments to accelerate disposal timelines to mitigate the threat of accidental exposure in border regions.
