not necessarily. there’s a direct rail link.
Yes and that was reinforced this past year.....Russia doesn't agree with the sanctions against N.Korea....because they see with China's easing off assisting N.Korea a gap they intend to fill and are.....plus they've opened the Russian internet to N.Korea and that's creating havoc in the technology war.....many of the hackers and thefts have come from N.Korea hackers though the demorats like to say it's Russia....which indirectly has a part in it by supplying N.Korea with access to their internet.
At any rate the rail is just the beginning stages for Russia's long term deals with n.Korea which has and will improve their infrastructure for Russia's long range abmitions in N.Korea.
