What was the outcome of Vernet's actions towards American sealing ships?

Vernet's actions towards American sealing ships primarily resulted in creating tensions that endangered significant trade. He imposed harsh regulations and restrictions on American sealing activities in the Pacific region, which directly challenged the interests of American merchants and seal hunters. This imposition not only affected the livelihoods of those involved in the sealing industry but also sparked diplomatic disputes between the United States and other nations involved in the Pacific trade. The heightened tensions had potential repercussions on trade routes and relationships, illustrating how Vernet's measures had far-reaching implications on commerce and international relations at the time.

The other possible outcomes reflect scenarios that did not encapsulate the immediate consequences of his actions as accurately, focusing on aspects like formal agreements or negotiations that did not transpire in the same manners as the trade tensions did.
