Eh, it's yet another meaningless resolution for the sole purpose of creating this screenshot. It's a 3 page document saying effectively nothing.

I mean, it was drafted by the following paragons of fighting for nation's right to self-determination:

Belarus, Bolivia (Plurinational State of), Botswana, China, Cuba, Democratic People’s Republic of Korea, Equatorial Guinea, Eritrea, Iran (Islamic Republic of), Lao People’s Democratic Republic, Nicaragua, Russian Federation, Saint Vincent and the Grenadines, Venezuela (Bolivarian Republic of), Zimbabwe and State of Palestine: draft resolution

Just to show how meaningless:

Reaffirming that any attempt aimed at the partial or total disruption of the national unity and the territorial integrity of a country is incompatible with the purposes and principles of the Charter of the United Nations

Russia co-drafted this btw

The reasoning behind each abstention can also (probably?) be read online. See Germany's:
