To the extent that Passio-Corum is a member of the USSO, citizens of the Pallisican nation are eligible to receive USSO passports which allow them to travel freely across all of the alliance's member nations.
The Pallisican Foreign Office is responsible for the foreign affairs of Passio-Corum.
Despite its expansive trade networks, which extend across much of Micras' eastern hemisphere, and despite its involvement in foreign conflicts, the Greater Pallisican Trade Association is officially isolationist in its foreign policy. In general, the government of Passio-Corum only engages with foreign governments in matters relating to trade, and military interests. That said, the nation for a long time enjoyed very few, loosely enforced treaties with a handful of nations. This changed with the establishment of the USSO. In terms of enemies, Passio-Corum has none, although Jingdao was regarded as a national rival until in an ironic twist of fate it became a strong ally and trade partner.
Formal relations between Passio-Corum and Craitland were adopted in early 2017. Positive relations are maintained between the two nations despite Gerenia's complete withdrawal from the USSO.
Despite the unreasonable and unfounded extreme animosity expressed by the Caputian government against Passio-Corum, the Pallisican nation still faithfully adheres to the Treaty of Bel Air as well as to the earlier Treaty of New Kirrie.
During the War of Lost Brothers Passio-Corum laid siege to the island of Talenore, which is now claimed by Iteru. This fact is the source of tension between the two nations.
Passio-Corum operates a puppet government in the Natopian territory of Normark. The existence of this puppet state is a source of animosity between the two nations.
