Japan investigates Chinese envoy on spying TOKYO, June 2 (UPI) -- Prosecutors in Tokyo have received documents from police in an investigation of a Chinese diplomat accused of of spying, an official said. Police officials turned over the documents concerning Li Chunguang, a first secretary with the Chinese Embassy in Tokyo, as prosecutors look into allegations Li used a false identity to get a foreign resident card, The Yomiuri Shimbun reported Saturday. Li also is suspected of participating in commercial activities banned under the Vienna Convention, most likely to secure a revenue source for the Chinese military from Japanese companies, investigative sources told the newspaper. Officials said the matter is the first time a Chinese diplomat was criminally investigated by Japanese police. Tokyo's Metropolitan Police Department's Public Security Bureau said that while Li is suspected of espionage, it is unlikely the diplomat will be indicted because he left Japan to "temporarily return home" May 23 after he was asked come in for questioning by police.
