China could easily just declare that they'd be willing to support Niger against the ecowas terrorists and then those dogs wouldn't dare to invade the country. I understand how China delivering arms to Russian forces in Ukraine might be too risky (although even then I seriously doubt the West would be stubborn enough to crash the entire world economy and cripple themselves just for their fascist puppet state) but what does China have to loose in Africa?
Do you understand that China jumping to defend Niger would be a casus belli for ww3?
China absolutely shouldn't get involved and they should focus on their national affairs. Solidarity and self-reliance between african nations is the only way forward.
