South Korea faces growing pressure to diversify its supply chains as new data from the Ministry of Trade, Industry and Energy reveals a deep dependence on China for key materials underpinning its high-tech industries. Information obtained by National Assembly member Lee Jae-gwan shows that South Korean strategic sectors remain overwhelmingly reliant on Chinese imports for essential raw materials and components.
The battery industry is among the most vulnerable. China accounts for 97.6 percent of South Korea’s natural graphite imports and 98.8 percent of synthetic graphite—both crucial for secondary battery anodes. Imports of precursors and nickel hydroxide, used in cathode materials, depend on China by 94.1 percent and 96.4 percent, respectively. The robotics sector shows a similar trend, with reliance on Chinese core drive components rising from 77.7 percent in 2021 to 80.3 percent in 2023.
Advanced display technologies also expose structural weaknesses. Over 90 percent of core materials for Micro LED displays come from China, while OLED materials such as dopants and fine metal masks depend on China by 67 percent and more than 95 percent, respectively. Of the 31 rare metals managed by the South Korean government, 20 are imported from China.
Semiconductor production faces comparable risks: niobium and silicon imports rely on China by 78 percent and 63 percent, while lithium—essential for battery cathodes—is 65 percent sourced from China. Other critical materials such as gallium (98 percent), graphite (97 percent), indium (93 percent), and magnesium (84 percent) also come predominantly from China, underscoring the urgency for Seoul to restructure its supply chains and reduce strategic vulnerabilities.
