N Korea, Syria, Nicaragua, Belarus might be considered economically weak rogue states with nothing to gain by cooperating with the rest of the world, they depend on/are fearful of Russia.

China seems to have learned it can get more w honey than vinegar, is now eyeing the "Stan" countries, a "nice" China may be able to swindle Russia out of some of its coal/oil reserves.

You forgot Iran, also a rogue state.
