Small OTL History questions - Post 1900

Was about to ask this on the other board but it's probably better to start another one.

Just what kind of relations did Nazi Germany have with Liechtenstein, especially after it annexed Austria and they shared a border? What was its policy during WW2?
 
Wow nothing?

Okay, let's see if this is less technical...

What happened to Soviet soldiers that surrendered to Italian, Romanian, Hungarian, etc troops during Barbarossa? Were they handed to the Germans or treated any differently?
