The 2020 Summer School brought together more than 70 participants from 25 Latin American and Caribbean countries and close to 30 expert speakers, including senior diplomats and heads of international organizations, a
hibakusha
(atomic bomb survivor), two Nobel laureates, and many world-renowned experts in nuclear weapons and associated materials, nuclear diplomacy, and international law.
This year's novel online format, developed by the Instituto Matias Romero, allowed for a much larger group of participants than ever before. The school ran for two weeks and was organized in conjunction with the Mexican Foreign Ministry, the Agency for the Prohibition of Nuclear Weapons in Latin America and the Caribbean, and the Instituto Matias Romero (Diplomatic Academy in Mexico City).
