41 Nations Urge 24-Hour Notice for ICBM and Space Launches After Chinese SLBM Test

Forty-one countries called on 11 August 2026 for at least 24 hours' advance notice before any launch of an intercontinental ballistic missile, a submarine-launched ballistic missile or a space launch vehicle. The joint statement was delivered to the Conference on Disarmament in Geneva and published by the United States mission there.

The signatories ask that a notification specify the class of missile, the launch window, the launch area and the planned trajectory, and that it be accompanied by the standard navigational warnings issued to mariners and airmen. The stated rationale is narrow and practical: advance warning reduces the risk that a test flight is read as an attack, and gives civil aviation and shipping time to clear the impact area.

The immediate trigger was a Chinese test in July. China fired a nuclear-capable submarine-launched ballistic missile into the South Pacific, notifying Japan, Australia, New Zealand and Papua New Guinea only several hours beforehand, which the group of 41 judged insufficient. China's ambassador to the Conference on Disarmament rejected the statement on 13 August, calling it political manipulation and accusing the signatories of double standards over their own arsenals.

The gap the statement is trying to close is a real one. The Hague Code of Conduct against Ballistic Missile Proliferation, the existing multilateral pre-launch notification mechanism, has 145 subscribing states — but not China, North Korea, Pakistan, Israel or Iran. Russia does subscribe to it and made no public response to the Geneva statement.

China's sea-based deterrent is the fastest-growing part of its arsenal. GlobalMilitary.net puts the Chinese inventory at an estimated 620 warheads, third behind Russia's 5,420 and the United States' 5,042, and its ballistic missile submarines are being armed with the JL-3, introduced in 2022 and credited with a range beyond 10,000 kilometers. On land the DF-41 covers the same mission. The American systems the statement would equally cover are the silo-based LGM-30 Minuteman III and the submarine-launched Trident II D5.

Timing is the whole point. Reentry vehicles released by an ICBM are among the fastest missiles in the world, and a launch detected without warning leaves the other side minutes rather than hours to decide what it is looking at. A fuller picture of which agreements still bind whom is on the nuclear treaties page, and the country-by-country totals on the nuclear forces hub.

The statement is political, not binding: it creates no obligation and no verification mechanism, and the states whose practice it targets are precisely those that did not sign. Whether it changes anything will be visible at the next Chinese or North Korean long-range test.
