Kammenos met earlier on Tuesday with Russian Ambassador Andrey Maslov to discuss strategic cooperation, including contacts between the Greek and Rusian defense ministries.
"I received an invitation from the Russian defense minister [Sergei Shoigu] to visit Moscow in the near future," the ministry quoted Kammenos as saying after the meeting.
On January 25, the deputy chief of an economic policy committee in Russia's lower house of parliament, Mikhail Emelyanov, said that Russia and Greece would have new opportunities for developing bilateral ties following the victory of the left-wing party Syriza in the Greek parliamentary election.
Back in December 2013, the two countries signed an intergovernmental agreement on defense cooperation relating to the supply of arms and military hardware. Shoigu and then-Greek Defense Minister Dimitris Avramopoulos also discussed the possibility of joint personnel training events.
