If we take just one country, China, out of the global poverty equation, then even under the $1.90 poverty standard we find that the extreme poverty headcount is the exact same as it was in 1981.

The $1.90/day (2011 PPP) line is not an adequate or in any way satisfactory level of consumption; it is explicitly an extreme measure. Some analysts suggest that around $7.40/day is the minimum necessary to achieve good nutrition and normal life expectancy, while others propose we use the US poverty line, which is $15.

It’s interesting that you argue for isolation when communism usually is a global approach.

I'm not arguing for isolationism at all. I'm arguing for the country to leverage its own resources and labour to meet its needs without relying on exploitation of other countries. In fact, this has to be the foundation for any sort of public ownership where the workers own the means of production.

That’s the exploitation I was hinting at. You want to keep ‘your’ resources instead of sharing them with the world.

That's not what exploitation is.

But even if you do, look at China’s history to know the problems that will come with that strategy.

The problems of having constant and consistent improvement of standard of living for its population without suffering economic crashes every decade as seen under capitalism?

Do you remember the end of the text? That virtualization will make any revolution unnecessary. If you want communist relations, you better come up with something new if you don’t want to find a new way to have working cooperatives.

The text simply explains the mechanics of financial capitalism which led to deindustrialization of the west. I do not have to agree with every single conclusion it makes. I don't have t come up with anything new because I'm perfectly happy with the kinds of relations USSR, Cuba, or China managed to achieve. I see these as a real and tangible improvement on relations in western societies under capitalism.

Nobody is stopping you from implementing your cooperativist utopia, but I'm simply explaining to you that it's an unlikely outcome in practice. You can do what you want with that.
