The UN General Assembly on Wednesday voted overwhelmingly against the move by Russia.
Nigeria along with 142 other countries in the United Nations General Assembly have voted to condemn Russia's attempts to annex four regions of Ukraine.
The UN General Assembly on Wednesday voted overwhelmingly against the move by Russia.
The resolution was supported by 143 countries, while 35 states - including China and India - abstained.
Along with Russia, four countries rejected the vote, namely Belarus, North Korea, Syria and Nicaragua.
Although symbolic, it was the highest number of votes against Russia since the invasion, BBC News reports.
Last week, in a grand ceremony in the Kremlin, President Vladimir Putin signed documents to make the eastern Ukrainian regions of Luhansk, Donetsk, Zaporizhzhia and Kherson part of Russia.
The agreements were signed with the Moscow-installed leaders of the four regions, and came after self-proclaimed referendums in the areas that were denounced as a "sham" by the West.
The resolution calls on the international community not to recognise any of Russia's annexation claims and demands its "immediate reversal". It welcomes and "expresses its strong support" for efforts to de-escalate the conflict through negotiation.
The countries which voted with Russia all have a longstanding stance of criticising Western governments.
Belarus is considered a satellite state of its neighbour and ally, and its territory was used in Moscow's invasion of Ukraine in February.
As well as China and India, which have attempted to remain neutral on the conflict, parties that abstained from the vote included 19 nations in Africa.
Many African countries have avoided taking sides in the war - which has been seen as a reflection of efforts to maintain longstanding trade ties, or of historic non-alignment policies.
Three of four states that were visited by Russian Foreign Minister Sergei Lavrov in July - Congo-Brazzaville, Ethiopia and Uganda - chose to abstain.
Meanwhile, all four nations that featured on a recent trip by Ukraine's own foreign minister - Ghana, Ivory Coast, Kenya and Senegal - voted at the UN to condemn Russia.
Ukraine's President Volodymyr Zelensky said he was grateful to the countries that did support the resolution.
"The world had its say - [Russia's] attempts at annexation is [sic] worthless and will never be recognised by free nations," he tweeted, adding that Ukraine would "return all its lands".
US President Joe Biden said the vote sent a "clear message" to Moscow.
"The stakes of this conflict are clear to all, and the world has sent a clear message in response - Russia cannot erase a sovereign state from the map," he said.
A statement by Antony J. Blinken, US Secretary of State, published on the website of the US Department of State, says, “Today’s remarkable vote at the United Nations General Assembly is a powerful reminder that the overwhelming majority of nations stand with Ukraine, in defense of the UN Charter, and in resolute opposition to Russia’s ongoing war against Ukraine and its people.
“Territorial integrity is a central pillar of the United Nations, and Russia’s violent contempt for Ukraine’s national borders and sovereignty cannot and will not be accepted. By adopting this resolution, the assembled nations made clear: they will not tolerate an attempt by any UN Member State to seize land by force. The vote delivers a resounding rebuke to Russia for its aggression against Ukraine.
“The United States is proud to have voted in favor of this resolution. As we have stated repeatedly, we will defend the principles of the UN charter and will never recognize the legitimacy of sham referenda or Russia’s attempts to annex portions of Ukraine.”
Dame Barbara Woodward, Britain's ambassador to the UN, said Russia had failed on the battlefield and at the UN, adding that countries had united to defend the world body's charter.
"Russia has isolated itself, but Russia alone can stop the suffering. The time to end the war is now," she said.
