A similar fare:
BUD/PRG - CKG (Chongqing, China) in J @ £1149 wide open until next year. (Min stay: 3 Days; Max: 12 Months)
Nothing too exciting, unlike ARN-SIN with QSuites, plus a Chinese visa might be needed if not transiting via CKG.
On the bright side, CKG has reasonably good & cheap options for int'l connections with AirAsis, MH, KA, CZ, MU, CA, etc.; so one can travel to elsewhere in CN or Asia easily.
An interesting route I found through this fare is that for a price of £1286, you can make stopovers at both HKG and DOH:
Outbound: BUD-DOH-HKG(stopover)-CKG Inbound: CKG-HKG-DOH(stopover)-BUD (you do not have to route it via HKG for Inbound I suppose, but it adds a 40 TPs more for BAEC)
Maybe people are more knowledgeable with fare rules than me can make a better use of this fare. For me, it just helped me slightly lowered the price for my 2 trips this year ARN-HKG and ARN-BKK; I did not choose the stopover option.
