Péter Szijjártó, Minister of Foreign Affairs and Trade, asked United Nations Secretary-General Antonio Guterres to intercede to advance negotiations between the United States and Russia in New York on Thursday.
After meeting with Guterres, Minister Szijjártó warned that the failure of the world's biggest powers to speak to each other presented an "extraordinary risk" in terms of global security.
"We also know well that it comes with the risk that the world will be divided into blocs again and we could return to the nightmare that was the Cold War," he added.
"I've asked the UN secretary-general to intercede in the interest of getting the global powers, the Americans and the Russians, to finally talk to each other," Minister Szijjártó said.
He added that an end to the Ukraine war would not be possible without American-Russian dialogue.
Minister Szijjártó said the UN needed to take up its original role as a platform for establishing dialogue between countries that were on bad terms or in conflict.
The start of an American-Russian dialogue could bring "new hope" for global security, as well as the security of Central Europe, he added.
