That "scrapping" is just propaganda from Trump. Have you heard from Xi that "Made in China 2025" becomes 2035? Even if China is to make concessions, how could China be able to scrap something that is a vision or objective? Vision and objective are not specific and measurable, not like import quota, tariff level by percentage etc. Nor is it enforceable by any agreement.
Let me put it simple, if China want to be the fastest runner by training hard, USA object to it, how could USA make sure of China does not train and practice? Even China choose not to compete with USA in next Olympic game so USA get the gold medal (being the nr.1 in name), China could still be the fastest runner (in fact) in the world measured in an open game or not. Blocking China to take the gold medal in Olympic is enforceable because it is physically defined and measurable, preventing China to run faster is not.
