US is used to being able to wage economic war on other countries because traditionally it has commanded a far bigger economy. Now, US is faced with an adversary whose economy is already bigger in terms of purchasing power, and continues to grow much more rapidly than US is. On top of that, China is now a more important trading partner than the US for the majority of the world. Attempts to bully China are achieving the opposite of the intended effect. China’s response has consistently been to make themselves less dependent on US, which is making China stronger.
