WATCH: Zelenskyy warns the world is 'now living through most destructive arms race in human history'

Ukraine's president said Wednesday that the world was "now living through the most destructive arms race in human history" because of the adoption of artificial intelligence in warfare. He called on world leaders to strengthen alliances and work to end Russia's invasion of Ukraine, which has stretch for more than three years.

“Stopping this war now and within the global arms race is cheaper than building underground kindergartens or massive bunkers for critical infrastructure later,”  Volodymyr Zelenskyy told the United Nations General Assembly. “Stopping Russia now is cheaper than wondering who will be the first to create a simple drone carrying a nuclear warhead.”

He asked for worldwide rules that detail how AI can be used in weaponry, calling the issue "just as urgent as preventing the spread of nuclear weapons." Ukraine's president also called international institutions, like the U.N., "too weak" to stop international conflicts.

“Weapons decide who survives,” he said. “There are no security guarantees except friends and weapons.”

Zelenskyy's comments come one day after he met with U.S. President Donald Trump on the sidelines of the annual U.N. meeting. Trump, in a shift on his own thinking about the ongoing war, said Ukraine could be in a position to win back its territory and criticized Russian President Vladimir Putin during comments on social media Tuesday.
