[1] In 1329, shortly after becoming count, Aymon established a committee to settle the territorial disputes with his cousin, Amadeus III of Geneva.

These disputes had been an ongoing feud between the families for generations, but they were able to resolve them through years of negotiations without resorting back to war.

Eventually, a settlement was reached whereby Aymon obtained the Countship in return for providing a monetary payment to Joan.

He spent much of his first few years as count at war with the Dauphin, Guigues VIII of Viennois, continuing a feud which went back for generations in their families.

[3] In August 1334, in the buildup to the Hundred Years' War, Edward III of England sent an embassy to Aymon to convince him to join the impending conflict on the side of the English.

Aymon declined to commit, as he held lands both in England and in Normandy, so was technically a subject of both kings.
