I'm going to have to be careful to not speak outside my lane and outside of my expertise.
I'll focus on competition law. Specifically dealing with trade agreements, there are provisions in the trade agreements that deal with harmonization of competition laws. However, in terms of the consumer protection side, I'm not aware that there is a detailed harmonization attempt, as you're suggesting. The trade agreements generally do try to link up competition policy and approaches. It's not clause by clause, so the devil is often in the details. There are attempts to co-operate and attempts to have similar types of provisions, but there is nuance. That sometimes really matters.
