Chinese authorities have indicted a Japanese citizen, an employee of Astellas Pharma, on espionage charges, escalating tensions between China and Japan amid ongoing territorial disputes and the Fukushima water release controversy. The man has been detained since March 2023, and his indictment has raised concerns over the impact on Japanese foreign investment and business relations in China. The Japanese government is actively seeking his release, while China's foreign ministry insists that investigations are lawful and rights will be safeguarded. In a related case, Yuanjun Tang, a U.S. citizen and former dissident, was arrested for acting as an unregistered agent of the Chinese government, allegedly spying on pro-democracy activists in the U.S. Tang, who defected to Taiwan and was granted asylum in the U.S., faces serious charges including making false statements to the FBI. These developments reflect increasing scrutiny on espionage activities and the geopolitical friction between China and Japan, as well as the United States.
