::::::::Most Communist states historically were, or continue to be, totalitarian with a rigid plan economy; embracing market reforms isn't necessarily coupled with as much socio-political liberalisation, they may remain authoritarian.  The clauses after the semicolon don't make sense and are improperly connected.  They also need to be sourced.  Secondly, your edit erased a whole paragraph of relevant and important information about the differences between socialism and communism.
