The US doesn't want a deal. China hasn't fallen far short in reducing it's necessity for crucial US high tech components from ICs to Jet engines. I think Xi gravely miscalculated early in his term beating his chest and acting like China is already a great superpower when much of China's technology still relies on crucial components from the US, a rival state, that cannot be replaced at all, unlike China's products to the US.
Xi has to act strong. I applaud him for island building in South China Sea. Steve Bannon hates him .
Why? Why do you think CCP allow him term limitless.
Because the party see him as a strongman, they entrust him the Holy task of completing the Taiwan Unification in his life time!
