I'm playing IGC 2.3 (EU 1.09) and have noticed that Dai Vet has been setting up trading posts and colonies in Siberia (circa 1560). Unless I am greatly mistaken, Dai Vet doesn't get any colonial dynamism from traders.csv or colonists.csv, so where are they coming from? Actually, how did they even get the maps? Not from me, and no one else has been to Siberia that I know of to trade them. Ayuttaya also has a couple of trading posts in SE Asia, does anyone know if they start out with these?
