A great way to expedite that transition is to disrespect them, treating them like your enemy when they're still your ally.
The convenient narratives spun to explain international politics seem entirely lost on people and are being treated as literal relations of how countries behave rather then shorthand.
"China" doesn't act like a person. It doesn't have emotions, moods or opinions like a person does. When we talk about "China thinks this" or "China feels that" we are not describing the moods of a human being, we're not even describing necessarily the aggregate mood of it's government except in so far as we're using a shorthand because we want to talk about trends in policy making or the types of people being appointed as advisers/policy-makers on whichever issue we are actually talking about specifically.
Alliances between countries are not formed in a rational way just on a specific issue normally, but based on previous actions and previous issues, and old loyalties. To betray those loyalties just means no-one will feel any loyalty to you - that may work in the short-term if you are big enough but long-term it's a terrible strategy.
So in that sense countries are like people, though I agree in many senses they are not.
Presumably spying on friends may be needed someday, but it brings the kind of diplomatic flamefest that should keep such spying restricted to Very Important Things and not just "we'll tap them because their numbers fell in our lap".
