Fair points.
However, African nations and entertainers have no power to broker any kind of peace. They bring nothing of tangible value to either side. The League of African Nations or a Russian pop star has nothing to hold a deal together. So, putting them in the peacebroker column is whimsical.
China, on the other hand, isn't whimsical, but serious. A Chinese brokered peace deal though is a serious threat to American power, as it would allow China to diminish US-European relations and foil the USian push to decouple Western-Chinese economic ties. It would stabilize and strengthen China's influence in the West.
That Chinese deal would have also allowed China to be a major player in the rebuilding of Ukraine, which would be an extension of its ambitious Belt and Road initiative. In other words, a Chinese brokered peace would have further ingrained Chinese economic and geopolitical influence into the European continent.
It had to be torpedoed.
I've read some folks also mention how it would also give China more credibility with leaders in the southern hemisphere-places that have valuable deposits of resources.
