The UN General Assembly's human rights committee, in its first action on Crimea, adopted a resolution drafted by Ukraine and backed by the United States, France, and Britain by a vote of 73 to 23 on November 15, with 76 abstentions, RFE/RL reports.
The resolution next month goes for a vote before the full assembly, which is expected to approve it.
Russia lobbied hard against the resolution, dismissing it as "politically-motivated" and "one-sided."
The people of Crimea "chose to vote in a historic referendum to reunite with Russia," said Russian Foreign Ministry official Anatoly Viktorov.
"It completely ignores the negative impact that the actions of Ukrainian authorities have had on the residents of Crimea," who have the same rights and privileges as other Russian citizens, he said.
Among the countries that backed Russia in opposing the resolution were China, Iran, India, Syria, South Africa, Kazakhstan, Serbia, and North Korea. Many Latin American and African countries abstained from the vote.
