but long term they will recover without problem.

You recon? Somehow I have my doubts. It does look like China had their moment and it's gone. They boosted economy mostly by creating huge amount of debt and growing GDP with housing/construction sector.
Now it does look like party is over. I'm not sure if China can recover (once they will fall into heavy correction) during our lifetime.

I am not sure whether you should neglect all of the investments into Africa.

I don't neglect those investments. I just think that most African countries will turn their back on China sooner or later.

It is one thing to give other countries predatory loans and it's a different story when those loans need to be paid back.
Time will only show.
