Yes, but if we want to be that pedantic, we should also specify that Xi is a person and not an economy. The person you replied to above did not say that China has a communist economy, they called Xi a communist. If someone is heavily influenced by Marxist-Leninist ideology, calls themself a communist, and leads a communist political party, it is reasonable to call them a communist.
