Yeah that’s not even remotely true. You can read or even watch the actual statements by China and Russia. The US has been the one vetoingball ceasefire action since the beginning. They put forth this resolution which called for a ceasefire to be examined except it would also allow for various continued operations that don’t count and added extra crap that doesn’t belong in a ceasefire. It also did absolutely nothing to address the concerns the US has had all these months, completely ignoring its own dire warnings.
