The party presided over by Nami herself gathered the elites of foreign companies in Ba Country, and the purpose of this party was very clear: to contract the two territories seized by Kasam from Yahward to a company for management.
Of course, Kasam was doing this to win over foreign forces and add a friendly partner beside him.
Thus, with inseparable interests, there would be assistance in resisting Yahward.
Kasam's people already controlled the two regions, Yahward's counterattack was inevitable. Others were unaware that Kasam had already handed over the management rights of these two regions to Chu Group; this information was just yet to be announced. Michael, representing Yahward, had promised not to attack these two regions. It's no exaggeration to say that Chu Group had already secured a lucrative deal making others envious.
