Africa is a big place .
Can you be more specific with a counrty?

Probably by NOT going to expat websites to ask such questions! You could, you know, try going to Chinese investment forums....

I know, absurd idea. I get them sometimes...

(one should also probably ask - if you're having problems in finding investors, it shows a lack of 'due diligence' checking ability. Probably very fortunate, if you're looking for Chinese investors!).

Avast ye buccaneers there be corsairs sailing close to the wind chasing some ivory coast dubloons. Put a mesaage in a bottle and drop it over the side at high tide. Ye be wanting some land lubbers for this treasure hunt.

You want to find people to give you money but you don't know how to find these people?

Hmmm...

Start sending random emails, like you represent somebody who won a large sum but cannot withdraw it in person. So you need somebody specifically from China to act as representative. For doing so, you will ask a sum to cover the document fees.

Or something like that.

Oh, to make it more credible, specify you come from Nigeria.
