I've been a diplomat for a while now, and I won't call “like-minded” a term of art, but it's a term we use to signify countries that frequently take common positions internationally on issues of concern to us, like protection of human rights or liberalization of trade. It's not political in any sense. It's about our foreign policy directions. When I said these four members were among the most like-minded members of the Pacific Alliance, I meant only that in our relations at the OAS, the UN, or bilaterally we find a lot in common with them.
