Because there is one major difference - Foxconn is mainly producing and assembling products for other companies and their business model is based on this. Kia create products for the consumer and has their own brand in the consumer market.I don’t understand why some people are so confused by this. Kia would be a manufacturing partner for Apple. Foxconn is also a manufacturing partner. Apple has invested in Foxconn as well. Does the name “Foxconn” appear on iPhone or other Apple products? No, because they are a manufacturing partner, not a co-branding partner.
