Delegations and observers will follow the proceedings on UN WebTV, which streams the daily plenary sessions and posts on-demand videos and statements for each speaker.

For New York residents and visitors, city authorities have briefed on security and services around the UN area ahead of High‑Level Week, as the city coordinates policing and transit while leaders arrive.
