I don't know about the "explicitly forbidden" stuff knfrmity is mentioning but here is my perspective.

The US and Europe heavily subsidizes grain production, which combined with their huge arable land share leads to an inmense surplus of grain, which makes it dirt cheap.

This makes it nearly impossible for global south countries, which have less efficient machinery and often very archaic land reforms that encourage small scale farming, to compete with. So in order to pay loans denomitated in USD, global south countries have to switch to an export oriented model of crops that are very resource intensive like produce or fruits.

Since the US and Europe control the grain supply of these nations, grains being the most important commodity for the food industry, they can starve them if they do not follow their commands.

The article is a big example of this, monetary speaking poppy is a very profitable crop but it does not feed the people, the imperialists want these nations to stick to these export crops to continue controlling their food supply and thus controlling their policies.
