A Japanese business person was sentenced Wednesday to three and a half years in prison in China on espionage charges, according to the Japanese embassy in Beijing. Japan's Kyodo News Agency described him as a man in his 60s and an employee of Astellas Pharma Inc., a major Japanese pharmaceutical company. Kenji Kanasugi, the Japanese ambassador to China, was present at the ruling but Japanese reporters were not allowed inside the courtroom, Kyodo reported.
