The Ukrainian president, Volodymyr Zelensky, will address the United Nations General Assembly in New York on Wednesday (NZ time).
He's expected to use his first speech to the gathering in person to stress the importance of territorial integrity, more than eighteen months after the full-scale Russian invasion of his country began.
Joe Biden addressed the assembly first and called for stronger condemnation of Russia's invasion of Ukraine.
New York correspondent Jody Jacobs spoke to Corin Dann.
