Having lived in several African countries and studied Sino-African relations I can say with certainty, that both Chinese and Africans couldn’t give less of a shit about what Bill Gates wants if there is a product that Chinese people want to sell and Africans want to buy.

No, that's not how trade functions. You can't sell what you want, where you want.

Trade is subject to lobbyism (to say the least)

[tfourb]

Sure, but the US or US-based businessmen are hardly the only actors lobbying and if you look at the trade balances of basically all African countries, Chinese interests are far more successful in exploiting African markets than US concerns. Add to this that several African countries have basically no diplomatic relationship and/or are openly hostile to the US and it makes no sense at all that they would forego a cheap and self-sufficient remedy to malaria (if it existed), just to please big Pharma.
