Japan's Foreign Ministry summoned the Russian ambassador in Tokyo on Tuesday in response to the detention of Japanese diplomat Tatsunori Motoki, who Moscow accused of espionage.
Motoki, a consul working in Vladivostok, was reportedly blindfolded, restrained and subjected to "coercive interrogation" during his arrest by the Russian Federal Security Service (FSB). Japan denied the espionage accusations and demanded a formal apology.
The accusations against Motoki were clearly fabricated and Russia's actions were unacceptable. This was a politically-motivated attack and a clear violation of the Vienna Convention on Consular Relations. Russia must issue a formal apology and a guarantee that similar incidents don't happen again.
Motoki was caught red-handed paying for classified information. His actions are incompatible with the expected behavior of a consular official and infringed on Russia's security interests. Moscow's response has been entirely appropriate and reasonable.
