A New Safe Haven is the trophy for freeing all 15 Mongol territories in Kamiagata. It is usually the last regional liberation trophy you get.
Clear every minor territory, major camp and stronghold in Kamiagata. Use the map to find any red zones left.
Finish this before Master Liberator, which needs all three regions.
