This document is a communication to the Soviet UN delegation in New York, written by Vasily Vasilievich Kuznetsov, the First Deputy Minister of Foreign Affairs. The Soviet Ministry of Foreign Affairs describes its contingency plan in case the US and UK refuse to sign the NPT in Geneva. This plan entails opening the treaty for signatures at the same time in Moscow, Washington, and London, using (presumably) the 1966 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies as a precedent for signing an agreement in three places at once.
