Partial Nuclear Test Ban Treaty
The most obvious manifestation of détente was the series of summits between the leaders of both superpowers and the treaties that resulted from those meetings. In the early 1960s, before détente, the Partial Nuclear Test Ban Treaty had been signed on 5 August 1963. Later that decade, the January 1967 Outer Space Treaty and the July 1968 Treaty on the Non-Proliferation of Nuclear Weapons were two of the first building blocks of détente. The early treaties were signed all over the globe.
