Here is the El Pais interview in which he says so. He may be right, but it’s not his job to state it and thereby accept war as a priority. I am glad he lauds the Chinese initiative.
However, the UN needs – and deserves – a more dynamic leadership, one that would dare to not only distance her/himself from Russia’s invasion but would also denounce NATO’s ill-considered, provocative and unnecessary expansion and massive armament of Ukraine for years.
This has never been a war between Russia and Ukraine only. And he and his staff should look at the conflict underneath the war – and address that.
