Check the different tariff rates, I think it's more possible a social media PR by BYD, or maybe just whitewash action by their fans.But SAIC is state owned by the Chinese government, So dont understandhow that happened. Anyway, its an inefficient car company. Private innovative and dynamic Chinese auto companies will put them out of business soon.
update: Just searched related news, seems both SAIC and Geely denied the rumour, BYD has no response yet.
