South Korea’s missed opportunities in the global lithium battery supply chain highlight a strategic divergence with China, according to industry analysts. A senior executive at a domestic battery materials firm noted that early investments in South American lithium reserves, such as POSCO Holding’s 2018 acquisition of Argentina’s Ombré Muerto brine project, could have positioned the country as a leader in the sector. “If a few more such cases had occurred, South Korea might now sit at the top of the global battery supply chain instead of China,” the executive said, citing the erosion of South Korea’s resource diplomacy following political shifts.
Historical Context of South Korea’s Resource Diplomacy
Under former President Lee Myung-bak, South Korea prioritized securing lithium resources in South America, where over half of the world’s reserves are located. The government and state-owned enterprises focused on acquiring stakes in lithium-rich regions like Bolivia, Chile, and Argentina. However, subsequent political changes led to the abandonment of these efforts, with public enterprises selling off key assets at discounted prices. This shift allowed China to fill the void, according to a report by the First Financial Daily (23 May 2023).
China’s Strategic Advantage in the Lithium Market
China’s dominance in the lithium battery sector is driven by its control over low-cost lithium iron phosphate (LFP) battery production. Data from the First Financial Daily shows that Chinese LFP battery sales surged 87.7% year-on-year in the first five months of 2023, outpacing global demand. This growth stems from China’s early investment in LFP technology, which requires less expensive raw materials compared to other battery chemistries. By contrast, South Korea’s reliance on nickel-cobalt-manganese (NCM) batteries has left it vulnerable to supply chain disruptions and price volatility.
Impact of Political Decisions on Resource Acquisition
The 2018 acquisition of Argentina’s Ombré Muerto brine project by POSCO Holding, valued at approximately 30 billion won, has become a rare success story in South Korea’s resource strategy. Current estimates place the project’s accumulated value at tens of billions of won, serving as a critical pillar for the country’s battery supply chain. However, this case remains an exception amid broader policy shifts. A 2021 study by the Korea Institute of Industrial Economics highlighted that political interference in resource acquisitions led to the loss of strategic assets, including high-quality lithium mine shares in Chile.
Comparative Analysis: South Korea vs. China
While China’s lithium battery ecosystem grew by 48.5% year-on-year in the first half of 2023, South Korea’s market expansion has been slower. This disparity reflects differing approaches: China’s state-backed investments in downstream processing and manufacturing, versus South Korea’s reliance on upstream resource acquisition. According to a 2022 report by the International Energy Agency, China controls 70% of global lithium processing capacity, compared to South Korea’s 12%. This gap underscores the long-term consequences of policy instability.
Future Implications and Policy Recommendations
Industry experts warn that South Korea must re-evaluate its approach to resource diplomacy to compete effectively. “Political judgments should no longer dictate strategic decisions,” one analyst stated. The government has begun revisiting resource acquisition strategies, with recent discussions on establishing a national lithium reserve. However, analysts emphasize that sustained investment in both upstream and downstream sectors is necessary to close the gap with China.
