Agreed, but I think Russia and China are significantly different.
Putin has doubled down again and again in Ukraine, his life is now tied to it, as he is unlikely to survive a loss.
Xi hasn't committed any kinetic actions that are linked to China at this point -- sure they are belligerent, but staying in the gray zone of hostile actions.
Everyone should be listening, and more than listening they should be preparing. Additionally there should be actions taken towards China that give Xi a viable off ramp to military collision. The Chinese population declining is a temporary thing, based on the now removed one child policy - a costly conflict could make that irreversible. Find a way to raise the Chinese standard of living - something the West failed to do with Russia.
History has shown time and time again, that a population that doesn't see a way out will cling to anything or anyone who will promise them a better life - even if it is terribly unrealistic.
