True, but that is irrelevant to the grand scheme of things. Whether or not Xi and the CPC leadership have different opinions, is neither important or even possible for us to know. All we can go off of is the policy position, and that policy position has been cold, calculating, and pragmatic. China will fulfill its own self interests first, and whether or not Xi finds it regrettable or wishes to support Palestine, Chinese leadership has little reason to care for the current conflict and the plight of Palestinians. They have bigger fish to fry, and this current stance is very much in line with the position they have taken for years on a myriad of conflicts.
