Roger is very much so ICAO standard terminology and means, I acknowledge receipt of your transmission.
It is NEVER a clearance, in no part of the world.
The required clearance would read: In case of go around climb to and maintain FL80.
I hope your airborne appearance is limited to simulator skies, otherwise I suggest to revisit an ICAO phraseology RT lesson asap.
I accept that, but therefore they acknowledged the intention to climb to FL80.
The fact they didn't deny a clearance to FL80 could have been interpreted as a clearance-by-omission.
I've never flown to Russia, but I know plenty of people who have, and their non-standardness extends beyond just units. Phraseology is not always from the ICAO textbook, and in this instance, whilst it should not be accepted as a clearance, it is very possible that the controller meant it as an approval.
