I'm sure that it could be argued that Sweden had Soviet influence, there was definitely a soviet-backed communist party in Sweden from 1917 until 1977.

But at the same time, Swedish Social Democracy is a completely separate ideology from Soviet Communism, and the parties that implemented these "folkhemmet" policies were 100% hostile to the Soviet Union and any Soviet influence. Sweden has never had any system of communism, nor any USSR-friendly prime ministers or ministers.

Specifically, Per Albin Hansson's "the people's home" ideology that he advocated for as prime minister was a reformist, anti-marxist form of social liberalism.
