Japanese worker detained in China over rare earth products

While Chinese customs authorities reportedly consider the employee's actions problematic, they do not suspect espionage. The detention comes amid heightened tensions between Japan and China, partly due to remarks made by Japanese Prime Minister Sanae Takaichi in November concerning a potential attack on Taiwan.

In January, China reinforced controls on shipments of dual-use items, including rare earths, destined for Japan. These materials are crucial for manufacturing high-tech goods like electric vehicles and weapons, and China holds a dominant position in their global supply.

This incident echoes a previous case in July last year, where a Chinese court sentenced a Japanese man working for Astellas Pharma to three years and six months in prison for spying. That individual, a former executive at the pharmaceutical company's China unit and a senior official of the Japanese Chamber of Commerce and Industry in China, was detained in March 2023.
