It faced rigid export policies including high duties and taxes that eliminated its cost advantages. It also struggled with bureaucracy in manufacturing and sales, a lack of trust between parent and subsidiary companies, and cultural clashes that increased administrative burdens and costs. Exporting the Nano to China involved high risks from political issues and challenges in distribution channels and establishing the brand in that market.
