Automotive tier-one suppliers are key players in the global automotive supply chain. They produce essential components and systems directly for major vehicle manufacturers, and their influence often reaches beyond mere manufacturing—extending into innovation, quality assurance, and supply chain reliability. When selecting where to outsource, these companies examine several factors, such as labor costs, regulatory environments, and supply chain infrastructure. However, the economic health, specifically the GDP growth, of outsourcing countries is a critical metric that should not be overlooked. One country that stands out in this regard is Vietnam. This rapidly growing Southeast Asian economy offers both immediate and long-term advantages for tier-one suppliers, making its GDP growth highly relevant.
