Russia's Prime Minister Mikhail Mishustin has formally abandoned a decades-old nuclear pact with Sweden. The 1988 agreement, signed between the USSR and Sweden, facilitated immediate notifications of nuclear accidents and information exchanges on nuclear facilities. This critical deal was initially established after Swedish nuclear scientists were the first in the West to detect alarming radiation levels two days after the 1986 Chernobyl explosion. The abandonment of this long-standing agreement follows Sweden's recent membership in NATO in March last year, amidst its growing concern over Russia's increasingly aggressive posture and its continued military aid to Ukraine.
