I should have said, I am a B737 Captain,
..Sorry thought you were a FO. In any case by all means yes,
politely ask but give a bit of leeway - if its a long trip offer to
leave the cockpit say every 2 or 3 hours so he can have a fix.
There's a lot to learn about Eastern attitudes and you will do
very well within such companies if you're known to cut your
crewmembers a bit of slack now and then. Remember EVERY
airline within the East encourages their FOs (and Pursers to
some extent) to report on expat captains - you don't want to
get too many offside in this matter esp if its a widely smoking
culture - and no one will secretly spit in your coffee either!
