Belarus: I could see CPB taking over when Lukashenko isn’t in charge anymore.
Burkina Faso: Their prime-minister seems to be a communist. Hopefully this means working towards a socialist state.
Cyprus: AKEL is one of the main opposition parties in Cyprus and their candidate for presidency went to the runoff election this year.
Greece: KKE is one of the main opposition parties and they keep growing.
Haiti: There are some revolutionary organisations involved in the protests against the government, maybe they’ll succeed.
Swaziland: The CPS is the main opposition to the king’s rule.
Taiwan: through reunification with PRC.
What others seem likely to you?
EDIT: I remembered South Africa is a candidate as well, the EFF is getting stronger
The “Communist” Party of India ("Marxist) are reactionaries who have done endless massacres against indigenous and lower caste people. They depend on the state to oppress them (and the revolutionaries currently taking part in the war, who’ve gained the support of the indigenous, Dalit, and people from other oppressed caste, who have been displaced, their forests getting used for the purposes of profit, and killed).
