Diplomatic Office

The Diplomatic Office is a diplomacy-related building used to establish friendly relations with other city-states. It is part of the broader diplomatic progression alongside the Exploration Office, Trading Center, and Bank. In practice, the Exploration Office is used first to reveal nearby terrain and the locations of other city-states, then the Diplomatic Office is used to make treaties, after which the Trading Center handles commerce.

When a foreign envoy arrives, the Diplomatic Office is the place where offers tied to investment and future relations are presented. The message emphasizes that the city may be seeking support for overseas development, and that accepting the proposal helps maintain good relations later. Refusing does not cause penalties in the dialogue, so the choice is presented as optional rather than forced.

• Use the Exploration Office before relying on diplomacy, since city-state locations are random each run.
• Build the Diplomatic Office to secure treaties and unlock the next step in diplomatic interaction.
• Pair it with the Trading Center if you want diplomacy and trade to develop together.
• The Bank comes later in the same system, allowing exchange and borrowing involving Pia and Dahl.
