Frequently Asked Questions
Can I build Trade Offices in my own territory in Europa Universalis 5?
No, Trade Offices can only be constructed in foreign nations’ territories. They’re specifically designed for establishing international trade relationships. If you want to boost domestic trade, you’ll need to build Trading Hubs instead, which are completely different structures with different requirements and benefits. Focus Trade Offices on expanding your economic influence abroad.
What happens to my Trade Office if relations with the foreign nation deteriorate?
If your Opinion with the host nation drops below 100 after you’ve already built a Trade Office, the building remains functional and continues providing benefits. However, if relations become hostile or war breaks out, the Trade Office may be seized, destroyed, or become inaccessible. Maintaining positive diplomatic relations is crucial for protecting your trade investments long-term.
