I have had no difficulty obtaining QNH for ops into Russia...and in fact it was provided just for the asking, by the folks in the tower, as they, at the same time, were polishing off the last bottle of adult beverage at Christmastime.
They also asked what minima we needed.
The First Officer replied 550 meters....and 550 meters it was, even though on the ground you couldn't see s***.
Friendly folks.
