Accordingly, this article analyzes Korea's dependency on imports for semiconductors and secondary batteries, noting significant increases in imports and the diversification of import sources. The analysis reveals Korea's high import dependence on specific countries for critical goods and materials, emphasizing the importance of supply chain cooperation with countries that have global export competitiveness.
