It's been a while since I've read that but as I recall, I don't think Loki is involved much.
This was mostly a conflict between Iron Man, Thor and Captain America. Thor cultists/worshippers in Slokovia are being persecuted and Thor tries to come to their rescue. But this doesn't go down well with Iron Man and Captain America since the country borders Latveria. Doom does meet with Stark but he's not directly involved. Doom does end up annexing the country once Iron Man and Cap convince Thor to back off but there's not been much mention of that since.
