Capitalists only want profit, and since they control the government of the West, it's very profitable for them to not sanction China nor Viet Nam so they could tap into the labour forces of these countries and use them for outsourcing labour.
Cuba and DPRK on the other hand are not as profitable since they do not really allow private enterprises in their country as much as the latter 2.
For Laos though, I think the West just doesn't know it exists and if it's relevant or not. I think we're just waiting for Laotian Socialism to become even more successful and Western media would create a thing called the "Hmong Genocide" or smth.
