“The stakes in 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.
Russia cannot change borders by force,” Biden said in a statement on the White House website.
He noted that Ukraine has the same rights as any sovereign state.
Earlier, the UN General Assembly adopted a resolution not recognizing referendums in the DPR, LPR, Kherson and Zaporozhye regions.
As Russia's permanent representative to the UN Vasily Nebenzya stated, UN General Assembly Chairman Chaba Kyoryoshi decided not to choose a secret voting format, "played for the authors of the resolution" and "did everything to manipulate the procedure of the General Assembly."
China said that the draft resolution does not meet the goals of de-escalating the situation and resuming dialogue.
On October 5, Russian President Vladimir Putin signed federal laws on the admission of the DPR, LPR, Kherson and Zaporozhye regions into Russia.
