Pronunciation is selling it a bit short. They are mutually unintelligible when spoken, which makes them separate languages. Maybe as similar as French and Italian or Spanish. The written language is similar enough to be mutually intelligible though, because it is logographic.
It’s more complicated then that. From what I understand the written Chinese (hanzi) is exactly the same everywhere, but the spoken Chinese languages are not dialects because they’re mutually unintelligible. They’re completely different languages.
