You're going to find China's history as wanting as the US's in that regard. Plenty of Chinese arms found their way to theaters of war in all corners of the globe during the latter half of the 20th century, and continue to do so in the Donbas today.

Or maybe you can look into what happens to nations in China's immediate neighborhood that resist Beijing's designs.

North Korea, a prison camp masquerading as a country, exists solely because of China. Had Mao not intervened on behalf of the Kim family, UN forces would have asserted control up to the Yalu. To this day, the Chinese have been breaking international law by helping Pyongyang dodge sanctions over the DPRK's nuclear weapons program. Same with Russia, actually, despite them both sitting on the UNSC, which passed the sanctions.

China also illegally occupies Tibet and has for over 75 years.

All of this points to a country very much not existing in harmony with the world.

As far as the US government being better, it's not about any given government being better. It's about whether or not totalitarianism can continue on peacefully. It cannot. This is evident on its face.
