To be honest, last time China accepted major trade deals from the West to fully open their market, they got their cities flooded by opium and got land ruled by foreign law, and then got their government toppled. The lessons learned from that was that if you are not careful, western countries will come and dominate you. Look around, the same happened in India and many other countries with often exctintion of natives

Fast forward to 2018, China and USA already agreed to WTO rules with China considered as a developing countries and thus granted special rights such as protection of its industries. Then USA unilaterally breaks WTO rules with tariffs with an arbitrary interpretation of "national security" and wants a signature of a one way deal where USA gets all the rights and controls but doesn't give anything. I'm sorry but history teaches you that kind of deals will get your citizens subjugated by foreign powers or foreign corporations.
