Sorry for not being clear. By "sacrificing in the short term" I meant "delaying" rather than "abandoning" or "reverting". Here is an explanation of my stance.
I'm sorry, I mischose my wording. They did not abandon any ideas or revert any socialist policies. By "sacrificing" I meant they chose to remain in a particular stage of socialism and delay any further advances in the path of socialism until the conditions allow. This is in perfect accordance with the revolutionary principles outlined by Lenin and even Mao (e.g. On Contradiction), and I see no problem with that strategy.
No, I'm not talking about markets per se. But there are different stages of socialism and China is in a pretty young stage at the moment, compared to a country like NK. There are still plenty of changes ahead, which will need to happen as the complex geopolitical situation in the world allows, notably as the West starts becoming less of a threat to socialism worldwide.
I mean, China has sacrificed some specific Marxist ideas in the short-term (edit: meaning "dealyed until safe", not "reverted" or "abandoned") in order to avoid being destroyed by the West like the USSR was. So it makes sense that some paranoid Marxists want to wait and see how the situation evolves before making their minds on the issue. I believe in the Communist leadership of China, but I can't blame others for being more skeptical.
Holy shit, they killed him right there. They have put the thread in "sort by new" mode and I bet it's just to bury that bomb as deep as they can.
