I suspected this so called trade and tech wars are American ways of pressuring China to stick to the dollar world order no matter what happen to the dollar value. America is terrified of the prospect China leading the world to abandon dollar. The US shot themselves on the foot when they seized 300 billions of Russia assets. Thanks to that, now resource rich nations, mostly autocrats, want to diversify reserve. If they are joined by the largest manufacturer and trading nation, China, that is hell of strength.
