Here is a write-up on the China part:

For broader geopolitical chess games the "Path to Persia" and "Extending Russia" papers are all time favorites.

The EU part isn't that explicit. It is a mixture of the US wanting to take the Greenland Arctic Sea route, sabotaging energy deliveries from Russia and making the EU dependent on US LNG. Now the EU is even more dependent on the US and there is no sign that the US wants Hormuz open. It is stalling, in my opinion deliberately.
