China doesn't invade the Middle East, China doesn't preach Communism globally. It's a really good question to ask who always really tries to spread their own influence.
As for peaceful, from Tienanmen square to how they deal with the Uyghurs to what is likely to be the case for Hong Kong they are anything but peaceful, even with their own citizens. If they were truly peaceful they wouldn't have to censor their own actions from their own citizens. If they wanted a peaceful solution they'd be happy keeping Hong Kongs current autonomy. Externally, they invaded Tibet, they would invade Taiwan if they could, most of their peacefulness comes from inability and not lack of desire.
I only come to hope to bring certain other perspective in peace and hoping for scholarly discussions on perspectives that I've not personally considered.
But of course it's all in the willingness of yourself to believe that there can actually be legitimate and unsponsored grassroot opinions not in favor of the West's perspective.
