I want to establish new departments/ministries please someone guide me... and one more thing.. how to construct embassies and establish relations with other countries?
Wrong forum, General is for discussing real-life topics such as politics. I recommend looking at Factbooks and National Information for roleplaying (which you seem to be referring to) and write some factbooks (found in the book icon on your nation’s homepage) if you want to flesh out your nation’s information. You can also check Frequently Asked Questions if you have further questions.
