No they didn't. This is in reference to the announced exceptions for electronics like phones, which is a pretty big category. That's effectively dropping tariffs on a big chunk. That announcement was then unannounced by trump but who knows. The general perception is that trump wants tariffs but will fold when the economy catches fire and wants China to make a big deal with him so he can claim victory.

Depends on what you mean by drop. Is rolling back dropping? Is making exemptions dropping? Because both of those things have been done lol
