Presentation slides on the Mengzhou manned spacecraft given at IAC 2024. Two versions of the Mengzhou are under development: one variant is for missions to LEO, such as ferrying taikonauts to the Chinese space station; the other is of course for landing taikonauts on the moon. They can be visually differentiated by their respective service modules and solar panels: the service module for the lunar variant is considerably larger in diameter, along with larger solar panels.

Guowang is not a pure LEO constellation.
When we compare G60 to Guowang, we are talking about the LEO constellation of Guowang. That's an apple to apple comparison.

There are Chinasat that went up previously like 16 and 26, but they are comparable to Viasat.

When people talk about the Guowang constellation project, they are referring to LEO satellites.
