I don't have any experience with Asiana but I did apply once for a job in Egypt that wanted 500 hours of B-737-800 PIC time. I had over 3000 PIC hours in the B-737-700 and only 35 hours in the -800. I was turned down as their goverment authority would only recognize -800 time as being valid for this position. How stupid is that, as the aircraft are for all practical purposes identical.

I think you need to keep in mind that you are dealing with people of a small mentality that don't have a clue about what they are doing.
