Is it ok to hug people in Vietnam?

I had an incident in Dalat that I gave my laundry to the hostel owner, and he sent it to the laundry company, long story short, this company lost my belt and the hostel owner was really nice and tried to find it for 3 days until he found it, I was so happy he found it I gave him a hug.. He seemed really weirded about it.

Same thing also happened when I gave a small hug to the local we played pool together, So I guess its not very socially acceptable to do?

I'm a male btw.

Edit: Wasn't expecting it would be also controversial outside of Vietnam, Obviously I don't just hug random people so often but if I really connected with someone and we happen to shake hands I might as well add a small hug with the other hand, nothing too crazy.
