Air China: SGN - FRA US$ 1,640 in J
 

Air China currently has a good fare in business class (booked into Z).
LHR is also available for about $ 200 more.

Below is a sample itinerary to Frankfurt but many other dates are available.
Maybe this is useful to someone. I will be flying from SE Asia to Europe later this year but prefer not to fly with CA.
