We explore how the outward FDI strategies of Chinese auto component MNCs are shaped by sub-contracting supply relationships established with developed market MNCs. We argue the strong presence of foreign MNC business networks developed through prior inward FDI constitutes an important home country effect influencing the outward FDI strategies of emerging market MNCs. Using the updated internationalization process model, we show how commitment to business networks is a critical mechanism driving the internationalization trajectories of Chinese auto component MNCs. This includes geographic location choices to psychically distant developed markets, strategic asset seeking orientation, pace of internationalisation and entry mode decisions.
