Yes, comrade Zyuganov brought up implementing Socialist economics to counter the economic sanctions at one of their party faction head meetings a little while back. Putin seemed to give some sort of positive acknowledgement but I see this as just realpolitik. The CPRF is the second largest party in the Russian Federation and the main opposition, now is a time where Putin needs as much unity within the country as he can get, so there’s no way he’s going to outright disagree or shoot down ideas from any of the factions at such a time, especially those that are already backing him on the current international situation. Putin isn’t dumb, I’m sure he’s well aware that after a certain point of isolation from the west, a neoliberal economy isn’t going to cut it anymore, so best case scenario he’s just saying he’s open for dialogue if the need arises later on.
