Achievement: Iberia or Iberia? Question about playing characters

[Glatcher]

Achievement has following interpretation:
"As an Iberian culture character, control all of the Caucasian Iberia region"

But does georgian character count as an iberian?

Or only this:
Andalusian
Aragonese
Asturleonese
Basque
Castilian
Catalan
Galacian
Portuguese
Suebi
Visigothic
