If you don't think I speak for Africa then go to any African forum or walk up to any group of African and say the nonsense you're saying and watch their reaction. You know nothing about Africa or Africans. We respect China but don't take it for granted.
So a couple of things about what you're saying, not in this post in particular but overall:
1. You want China to respect the global south.
There are different types of respect. One type is respecting that you have your basic rights and they are not to be violated. You have this from us. China does not violate and colonize people like the West does. However, the second type of respect is viewing someone as your own equal or near equal. This you cannot have, or ask for, from anyone. This type of respect is only earned by your own power and competence and it is given to you automatically, regardless of alliance, based on your achievements.
2. You don't want the new boss to be like the old boss.
Yeah, but you do still have to realize they're both bosses. China can be a kinder boss who does not violate your rights or exploit you and even helps you out but you are not your boss's equal and do not confuse his kindness with him being on the same level as you. "Balance" doesn't mean that that power is distributed evenly regardless of national power. And unlike your old boss, this new boss can afford to not exploit you precisely because China gets our power from within and have plenty to dig from while the old one needs to suck power exogenously to make up for his own weaknesses.
3. China needs the world so don't waste the good will.
Whatever China gets from the world, we do not get it from their goodwill or because they support us in our rise. We deal for the things we get and we pay for them. We got them because we were the highest bidder and they were acting in their own interests to sell to the highest bidder. It is not uncommon that we need to be the highest bidder by a large margin to compensate for their fear of ending up in America's crosshairs for dealing with us. Oftentimes, we give freebies to the global south, never the other way around. And you traded these things to us for the benefits that we respond to you with. Don't make this sound like we got strong from your charity and support and now we're being arrogant and not acknowledging it. We rose on our own power and gave a bunch of you guys lifts up too on the way. If we're arrogant, it's because we achieved everything we got from our own power and we're achieving more than ever.
To end, I don't believe in forcing the weak to serve us; that is clearly evil colonialism. I believe in strongly rewarding those who support us and building mutually beneficial relationships with them so they can far outgrow and outstrip those who are stubbornly against us. Getting left back will be their punishment.
