BERLIN, April 14 (Reuters) - Volkswagen said on Sunday it will build a fully electric sports utility vehicle for the Chinese market from 2021, entering a segment dominated by Tesla's Model X.

The new SUV is the latest in Volkswagen's aggressive roll-out of electric cars in China, where zero emissions vehicles are given preferential treatment by authorities.

VW said its ID ROOMZZ will have three rows of seats and an operating range of up to 450 kms. (Reporting by Edward Taylor Editing by Alexander Smith)
