Re: "before" and "after" scorecard?
It's hard to describe in simple detail what the USA wants, perhaps if you think of it as a 'level playing field' in Asia.
1) Western companies cannot set up a Chinese company without a Chinese "business partner" (note: probably why there are so many Chinese billionaires). So far, Tesla is the only exemption.
2) Many Western tech companies are explicitly banned in China. Facebook, WhatsApp, Google, Amazon prime, YouTube, twitter, Netflix, Microsoft search, Google maps etc. Are all blocked/banned at network level. Quid Pro quo, I assume that's why Huawei was recently "banned" from EU/USA for flippant reasons.
I think China just agreed to buy some stuff, probably without huge concessions in this deal.
