"Mercantilist nations"
Do you have a reference I could read on this subject? I thought merchantilism featured a vertically integrated mother country to and from colony trade structure. Not predatory monopolistic policies you are describing.
That probably is the truest definition of mercantilist. The term today is often used to describe nations that follow predatory trade practices to help build their industry at the expense of a host country. Try googling for more details.
