For the record, this is what the NK rep said before voting against Ukraine (note the incusion of Kehrson and Zap):

"SONG KIM (Democratic People’s Republic of Korea) stressed the crucial role of the right to self-determination, adding that the people of Luhansk, Donetsk, Kherson and Zaporizhzhia have the right to decide their international political status at their own discretion. The people of those regions have exercised their right through a referendum held from 23 to 27 September 2022, he said, adding that his country respects their will. They aspire to integration into the Russian Federation, he said, adding that the United Nations Charter and international law must not be applied in a selective and partial manner. The sovereignty and territorial integrity of former Yugoslavia, as well as Afghanistan, Iraq and Libya, were violated brutally by the United States and other Western countries, he said, adding that such unlawful and illegal acts have never been called into question in the Security Council."

I will not dispute the sovereignty claims, but I am not aware of any changes whatsoever to the territorial integrity of Afganistan, Libya, or Iraq. Yugoslavia dissolved of its own accord, but there were no changes to the overall territory.
