Aston entered the DTM in 2019 via partner squad R-Motorsport, which was granted an exclusive license to build and run Vantages to the Class One rules the series adopted last year.
R-Motorsport tied up with HWA for this purpose, but the two parties split at the end of the year - and R-Motorsport recently announced that it will not contest the 2020 DTM season.
HWA and R-Motorsport had originally agreed to sell the cars to a buyer in Hong Kong but the deal didn't go through because of civil unrest in the Chinese special administrative region.
