well it does matter because not everyone is Putin stooge. If Lula and Zelenskiy do the song and dance of peace Putin would be cemented as unreasonable party who will call even his allies the west unless they hand him everything he wants. China's plan was a nothing burger, but Zelenskiy who initially was frustrated with it has moved into "we'll talk about". the goal is to isolate Russia rhetorically and eventually Economic. about moving the needle even in India where there is a cynical self interest about "if we play nice with Russia we'll get their stuff when they croak"

Also Vietnam happen in a free society, where the loses could be seen but the benefits of victory weren't. in Russia it is the opposite, a society of brutal repression and where the nationalists have clear goals and "benefits"- i.e. seeing those regions in the Russian landmass.
