Talks weren't suspended because the EU hates Turkey (national politics and sentiment nonwithstanding Berlaymont just doesn't care about those things) but because the accession procedure went nowhere, and in some areas backslided.

As such reopening is contingent on nothing but Turkey actually taking its prospect of joining seriously. I wonder if Erdogan understands that "Sweden reinvigorating Turkey's application" pretty much means Sweden giving Turkey private lessons in how to be less of a shithole... in any case it doesn't surprise me that Sweden agreed to such language.
