Denying communism and introducing capitalist reforms was kind of Nikita Khrushchev's thing to be fair.

Khruschev introduced no capitalism. He simply stopped Stalin's terror policies. And there's no such thing as communism in the whole history of humanity. All that has been "attempted" was socialism. Communism means NO STATE whatsoever.

I say this as a Maoist: Nikita Khrushchev was a revisionist striving for "peaceful coexistence with capitalism".

I would also include countries who are striving to attain Full Communism in the definition of communism.

Well, the Hutterites practice what could be called small-scale non-state communism. But I take your point.
