I'm sure there is some multiple ways Russia can be excluded from the UNSC using off hand tactics. Whatever way they try, it will immediately isolate China and a multitude of other countries.
The UN will just become another expensive government building in New York, able to pass whatever resolutions it wants but it won't change anything internationally. A UNSC condemnation of the Ukraine war without Russia, China means the exact same as the US government just making the announcement. The UN is powerless without it's members.
It was one of the reasons China was eventually readmitted to the UN. There's no point in the UN existing if the biggest country isn't part of it.
