Probably unrelated:
Before the vote, a statement was made by the representative of the Russian
Federation; statements in explanation of vote were made by the representatives of the
United States and Ukraine.
while in meeting #15, on the very next day, the vote called
"A global call for concrete action for the elimination of
racism, racial discrimination, xenophobia and related intolerance and the
comprehensive implementation of and follow-up to the Durban Declaration and
Programme of Action"
Ukraine obstained, while USA voted "N" (No).
I think there has to be shed further light on this issue, because the reasonings of Ukraine and USA of voting "No" for draft resolution "A/C.3/75/L.49" (70a) are not given in context here. I admit, this looked strange to me as well, but further investigation is needed to get more detail.
If USA and Ukraine would have voted the same in similar drafting votes (as outlined above), this would look like a no-brainer, but this way it's worth to investigate before blaming or accusing anyone. Nobody knows why the US and UA voted against this draft, but the details could be clarifying.
To sum it up: Don't judge based on the first look of something.
