A bit of a generalisation about Asians but that the African "governments" are to blame I believe is absolutely correct. The African leaders sell commodities to those from whom they can get the best kickbacks into an opaque bank account (or Dubai in the Gupta case). This seems to be condoned if you look at SA and say, Angola. That those who promote and protect such actions, like Mbeki, also whine about it is an ironic sidebar.
