Police are investigating a Chinese diplomat suspected of conducting espionage and unlawful commercial activities during his stint in Tokyo, investigative sources said Tuesday.
The police in mid-May asked the Chinese Embassy in Tokyo via the Foreign Ministry for the diplomat to turn himself in for questioning over activities considered in violation of the Vienna Convention on Diplomatic Relations, the sources said, without naming the suspect.
But the embassy turned down the request and the 45-year-old first secretary, who was from an intelligence unit of the Chinese People's Liberation Army, returned to China, according to the sources.
