that's not how doing business in china works, also, since it seems many aren't aware of this fact, NetEase are on the CCP's shitlist and are actively falling apart as a company within China, so Relapses 'reading between the lines' bullshit has nothing to do with the two companies 'falling out', it's more than likely that blizzard needs certain assurances in place alongside the current 'middle man' that NetEase provides which is something ActiBlizz wants to have before renegotiating their contract.
In terms of jumping ship and trying to get in bed with another company to provide them with the 'middle man' they need to legally operate in China, the CCP has cracked down on international companies aligning with both state owned and 'private' enterprises within China over the last couple of years and it's now even harder for companies to establish a legal and fair partnership in order to do business within China as a result, and the 'mutually-satisfactory' wording is more likely referring to keeping NetEase and the CCP on side than anything ActiBlizz is after.

i could be wrong but last time i bothered looking at things like that i think microsoft is one of the very small number of companies that can sell to the chinese market without needing a 'middle man' operator, due to what microsoft produced historically and how ubiquitous it was with the technological revolution which China bought hand over fist to try and catch up with the likes of the US and such, unless things have changed they are able to directly interact with the Chinese market.
