Russian Prime Minister Mikhail Mishustin has ordered the cancellation of an information sharing agreement with Sweden on nuclear accidents and nuclear facilities, after Stockholm joined NATO last year.
The relevant document was signed by Prime Minister Mishustin on June 24 and published on the state's legal information portal on June 27.
The agreement, signed by the Soviet Union and Sweden in 1988, came into effect in April that year, stemming from the 1986 Convention of the International Atomic Energy Agency (IAEA) on Early Notice of Nuclear Disasters, in which members agreed to notify each other of any nuclear disasters on their territory that could affect other countries.
Scientists at the Swedish nuclear power plant in Forsmark were the first in the West to discover the increase in radiation levels on April 28, 1986, two days after the explosion at the Chernobyl nuclear power plant in Ukraine.
Sweden joined NATO in March 2024, abandoning its long-standing neutrality policy. Sweden has provided nearly $1 billion in military and other assistance to Ukraine since February 2022, and launched a major domestic rearms program.
Constitutionally, Russia remains a successor to the Soviet Union, fully held in debt by the bloc when it was dissolved and Moscow recognized international treaties signed by the Soviet Union.
Russian Ambassador to Stockholm Sergey Belyaev told RIA Novosti that Stockholm's stance "sees that Sweden has completely lost its position as a neutral state and is becoming a springboard to realize NATO's military ambitions".
