Russia's Federal Security Service (FSB) has said that it detained and ordered the expulsion of a Japanese diplomat in the eastern city of Vladivostok for suspected espionage after the consul allegedly sought "restricted" information.
It said the diplomat was caught receiving the information, on the economic effects of Western sanctions, in exchange for a "monetary reward."
"A Japanese diplomat was detained red-handed while receiving, in exchange for financial reward, restricted information about Russia's cooperation with another country in the Asia-Pacific region," the FSB said in a public statement on September 26.
The diplomat was named by Russian officials as Vladivostok-based consul Motoki Tatsunori.
The Foreign Ministry said Tatsunori had been declared persona non grata and given 48 hours to leave Russia.
There was no immediate confirmation from Tokyo of the incident.
The accusation and expulsion come with Japanese Prime Minister Fumio Kishida so far joining international sanctions including asset freezes on Russia over its unprovoked invasion of Ukraine that began in late February.
