A court in China sentenced a Japanese businessman on Wednesday to three and a half years in prison for spying, Tokyo's ambassador in Beijing said.

The man, an employee of the Japanese pharmaceutical company Astellas Pharma, was detained in March 2023 and placed under formal arrest in October 2023.

He was "sentenced to three years and six months in prison for espionage activities," Kenji Kanasugi, Japan's ambassador to China, told Japanese media after the trial in Beijing. "It is extremely regrettable that such a guilty verdict was issued," he said.
