Russia has a number of means to respond to Japan's unfriendly actions, Russian Deputy Foreign Minister Andrei Rudenko said.
"I can assure you that we still have something in our arsenal to respond to if Japan continues its current course," the diplomat told TASS.
He recalled that Moscow has already taken "many steps" in response to Tokyo's unfriendly actions.
"We have frozen contacts actually at the political level. After Japan supported the policy of sanctions of the United States of America, we have frozen negotiations on a peace treaty and introduced a number of other measures that I would not like to talk about," Rudenko said.
As reported, on April 10, Russian Foreign Ministry spokeswoman Maria Zakharova, in connection with Tokyo's decision to join the work of the NATO Center for Security Assistance and Training for Ukraine, said that Russia would take inevitable and tough retaliatory measures to any steps by Japan to participate in supplying Kiev with weapons. The diplomat stressed that Japan is becoming more and more involved in the conflict over Ukraine, expanding logistical support for the terrorist regime in Kiev. She warned that any steps by Tokyo to directly or indirectly participate in supplying Ukraine with weapons and military equipment that will be used to kill Russian citizens, to assist in the training of Ukrainian militants are viewed by Moscow as unequivocally hostile.
