Following the Second World War, the Kingdom of Afghanistan and the Soviet Union formed a friendly relationship, and the latter provided much aid and development to Afghanistan. Following the Saur Revolution, the two countries signed a friendship treaty in 1978. In 1979 the Soviet Union intervened in Afghanistan with Operation Storm-333. This action precipitated a negative reaction in most of the Muslim world deeming it as an invasion, and contributing to a decline in Afghanistan's prosperity and a strengthening of radical elements within the country. The Russian-backed Afghan government collapsed in 1992. However, Russo-Afghan relations have improved somewhat in the years following the conflict. Russia now has an embassy in Kabul and a consulate-general in Mazar-e-Sharif, and Afghanistan has an embassy in Moscow.
