Japan and Russia resumed on Monday a ministerial security dialogue for the first time in over three years. But the talks are seen as a symbolic development rather than substantial, and may have only served Moscow's interest in showing its improved ties with a Group of Seven country.
Russia remains wary of U.S. missile defense abilities in the Asia-Pacific, while Japan is in a position to strengthen ties with Washington to counter North Korea's growing nuclear missile threat.
As a key security ally of the United States, Japan needs to convince Washington if it wants to take steps on any security cooperation with Moscow, analysts said. U.S. President Donald Trump's policy toward Russia remains unclear, but he has signaled a willingness to work toward a better relationship.
