Global peace produces trade between countries.

Question

is that because those trading nations would be at ease with each and trade at their own will. Negotiations would not have to be made because everyone would be getting along with each other. Or is that not the right direction???

Answer 1

Negotiations are always made between the buyer and seller.

However, during a war, the combantants and their allies don't usually trade with each other. However, during peace, countries are free to decide on their own trade agreements.
