Deeds not words. As far as that goes Russia track record in this matter is stellar compared to the US.
To go from the Kara sea to the Leptev Sea in the Russian Arctic, the 'easy' way takes you through a narrow land passage. I don't recall it's name, if it has one.
The Russians don't care if you call it 'internal waters' or 'international waters'. Suit yourself as to what you call it. They have big nuclear powered ice breakers and destroyers above the water, and great big nuclear powered subs below the water, and if you want to pass that straight you will be renting heir icebreaker and their pilot.
Even in summer.
Like Bart said with Americans - don't trust them when it comes to fresh water, or land disputes. With Russians, you can trust them . . . once they are paid.
