Second question is why did neither fare equate the published accepted fare, they were both higher? Third question is how much longer are we going to tolerate this cloak and dagger, completely invisible process behind the curtain? And fourth question why are we still dealing with it years and years after the problem surfaced?
1- Because they're an international flag carrier based in China and PVG is in China.

(if you're asking why they're on the pairing DH, probably because the contract doesn't say they can't be.

)
2- Because our accepted fares are published much too far in advance and then the fares go up by they time the tickets are purchased.
3- At least until the next contract is signed.
4- Contractual language (or lack thereof).
You're in a slightly different situation since your duty day on that DH appears to be under 16 hours (flight time seems to be ~11 block hours).
If I'm wrong and it is an over 16 duty day, you could get an email from corp travel, deviate, buy a FC ticket on Air France and it wouldn't matter what the accepted fare was.
