If that was true, they would be collaborating with each other and opening up all the results from their work.
The Chinese are genociding Uyghurs as we speak, purely for being Muslim, in numbers that dwarf any harm the US has done.
The list of wars the US is or was actively involved in[0] is SO LONG that the Wikipedia page is split into multiple different pages.
The main relevant ones are 20th[1] and 21st century[2], for which you better get a good grip on your mouse to scroll down.
I urge you to use your favorite AI to give you a rough summary of direct and indirect casualties of just those wars directly caused, started, or provoked by the US, from these lists.
For example, the "war on terror" alone has, so far, seen around 4.5–4.6 million+ people killed, and at least 38 million people displaced.

Nothing China did comes close to this.
its not, this would require voted resolution to declare genocide. It was some report on inquiry by individuals with unknown bias.
