My suggestion was not for the current leader (GenSec Xi) but the leader(s) of tomorrow when China's status as the pre-eminent power is beyond reproach.I just don't think the President of China himself is gonna get involved in any discussions about Israel - Palestine conflict. It's a very sensitive topic. Xi Jinping is the President of China. While he is a very powerful person, he is still beholden to the CPC and China first. So if there are any opinions, it would be a CPC decision about what that is, and would be conveyed via proper channels, like their diplomats. That is how the Chinese government works. Its a machinery made up of people, not a one-man show.
I don't view Xi Jinping as a charismatic politician. And that is not a negative thing for me. Not every great leader must be charismatic. He is doing his job better than the vast majority of world leaders out there. If he does that quietly, then so be it. He is a serious leader, and that is best for China.
Despite all the accusations by the haters that Xi Jinping is building a cult of personality, he has been very low profile. We don't see him posting stuff on social media. We don't see him getting into interviews with journalists. We don't see him pulling out PR stunts like flying in a strategic bomber, riding in a tank, swimming in ice water, scuba diving, or praying in some temple. Whatever we get is just some snippets of his life story. Xi Jinping had always presented himself as a part of the CPC and China, and never about himself first. I think he is much more respectable than the majority of world leaders out there.
Some countries need charismatic leaders to lead them. Because of their social, cultural, historical, and political circumstances. It is only once in a lifetime, that people finally find a charismatic leader who genuinely cares about the nation. People like Anwar Ibrahim or Putin. Most of the time, they're getting snakes like Modi, Erdogan, Marcos Jr, Trump, etc. People who are very good at talking are more often than not, untrustworthy snakes. If charisma is not a must have, then more genuine leaders could be found. It is fortunate that China has perfected a political system that does not necessitate needing charismatic leaders.
I should have qualified my post but I do agree with the points you made and especially @plawolf
