Nero could not call himself an expert on foreign policy, nor was it a topic that was covered in school so far. At most they established, with broad strokes, the relationship Kolar had with the other countries.
Kolar was not on good terms with Saint Codale and Dolziya, considering the multiple wars they'd had in the past. The accusations against Kolar for assassinating multiple Saint candidates didn't help much either, nor did the fact that Dolziya was heavily suspected of sponsoring every kind of illegal activity that took place in Kolar.
The relationship with New Velariya was tense, but mostly neutral due to the fact that the residents of the country saw themselves as too superior to concern themselves with the rest of the world. It did not help that they were, in fact, at the forefront of Eldrim card research and manufacturing in the whole world. They also didn't share a border with Kolar, so conflicts were usually kept to a minimum.
