What historical event happened outside the US in 1996?

In 1996, one significant historical event outside the United States was the signing of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) by 71 countries at the United Nations in New York. This treaty aimed to ban all nuclear explosions and promote disarmament, reflecting growing international concern about nuclear proliferation.
