I have a lot of respect for Kissinger. But his contact with China was prmarily from the 70s and 80s, when the relationsihp between China and the Soviet Union was at its low point. Besides, did the Chinese and the Americans have anything good to say about each other until the late 60s?
Of course nothing is certain. But the US and China overcame the bloody Korean war to become allies against the Soviet Union for a few decades. Now Russia and China face similar common threat from expanding NATO while having less hostility to begin with than when Kissinger bridged the gap for China and US.
Grandeur was what Macron needed because Macron is the swing vote between China and the west and Xi was supporting Macron in his domestic struggle. Interactions between Putin and Xi has always been much more intimate between idealogical allies. Imagine Macron and Xi making pancakes and eat icecreams together. Or Xi and Putin listsens to traditional Chinese music.
