"Permanent Representative of the United States Nikki Haley with kind and courteous request to refrain from naming any legitimate governments, from labeling them as regimes, and specifically, I am referring to the Russian Federation," Nebenzia said.
"Now I will state this personally. Next time I will halt the meeting for a point of order if this takes place again," Nebenzia said.
In February, Nebenzia called on Haley and the US delegation to the United Nations to observe diplomatic decorum and not refer to the Russian authorities as a "regime of President Vladimir Putin."
Haley repeatedly referred to various governments by the term "regime," including the governments of Russia, Syria and North Korea.
