I don't know why you guys are being so asinine about an African who wants to see Africa industrialise. It's a matter of national self respect. The biggest leverage they have is their natural resources so it's completely expected they offer that in return for factories.
Developing countries absolutely should have tariff barriers to promote industrialization. There's a big reason why many Africans are fans of the CCP, they want to learn from them. I find African commentators are a lot less delusional than Indians, they aren't fantasizing about supapowa 20xx.
That said, I predict that economies like Australia (exports raw materials/low manufacturing) are going to do a lot better than economies like Europe (few raw materials/strong manufacturing) because being primarily a raw materials exporter means you aren't in a hunger games manufacturing death match with Guangdong.
Australia and New Zealand might be the two Anglo nations most insulated from the upcoming crisis, at the terrible cost of falling into the Chinese sphere. But I suppose with China's manufacturing, the conversion rate between NZ wool and Australia ore to manufactured goods will be high enough to ensure a comfortable life for both nations citizens.
Developing countries should co-plan their industrialization with China, so that China does not swallow their industries whole. China could even partition out several sectors that those nations would monopolize. Ultimately, if the goal for both China and the developing country is balanced trade, such a goal can only be accomplished via coordination.
Strong border guards will not solve that problem unless a country mobilizes their entire population. Industrial countries want to get rich by being productive economies then keep everybody else poor by being low productive economies, won't work and eventually something will give. You can't skew the global economic system in your favor and expect nothing to happen.
Tbh, as the industry becomes more and more capital-intensive, and profit margins drop as a result, the ratio of raw materials to finished goods tilts in the factor of the raw material exporter, unless the owner of such industry chooses to monopolize those goods. The western countries often monopolize technology in order to keep the price artifically high, but in theory, a manufacturing economy should see its profits frittered away by heavy capital investment.
