No worries,
PVG-MAN-DUB is certainly feasible if a carrier was looking for a tag route, however MAN's best chance at a China route would be by far and away Hong Kong. Not only because its the biggest unserved market from MAN by a long country mile, but Cathay Pacific already send freighters to MAN and keep saying they will open MAN-HKG when the A350's arrive.
The next biggest route is Beijing and Air China have now publicly said they are looking into opening MAN flights.
