At least two Chinese carriers have recently issued policies with the effect that most travellers can cancel tickets with a full (end expedited) refund. I know of CA and MF.
On one hand I'd say it is very uncharacteristic of Finnair to take such measures. OTOH, could they be forced to? Anyone care to speculate on that?
With the reliance on China as main market, that could quickly ground a big portion of the fleet.
