According to the detailed performance data published by Airbus, a Trent 700 powered A332 could take off from EDI at 11,000kg less than maximum take-off weight of 233,000kg on a standard day. PVG is 4,888nm great circle distance from EDI and the prevailing winds will generally assist. That should be enough for a full pax load and a decent amount of cargo.
