TOKYO, September 27. /TASS/. Russian Ambassador to Japan Mikhail Galuzin has been summoned by the Japanese Foreign Ministry and handed a note of protest regarding the detention of Japan’s consul in Vladivostok on September 26, Kyodo news agency reported on Tuesday citing Foreign Minister Yoshimasa Hayashi as saying.

Hayashi stated that Russia violated the Vienna Convention and its move is "totally unacceptable," according to the news agency.

The Japanese minister said that Tokyo demanded apologies on behalf of the Russian side as the detained diplomat had never been involved in any illegal activities and also urged against any repetitions of such incidents.
