Highlights

• Korea seeks to reduce 90% rare earth metal dependency on China by developing alternative sourcing through Vietnam.
• Dysprosium prices spiked threefold after China's April export restrictions on rare earth metals and magnets.
• Korean firms are exploring new critical mineral projects with Vietnam to mitigate geopolitical and supply chain risks.

The Korea JoongAng Daily piece published August 12 paints a clear picture: Korea, long reliant on China for over 90% of its rare earth metals, is tightening ties with Vietnam to diversify supply chains for semiconductors, EVs, and defense applications. The catalyst, according to the piece, is China’s April export curb on certain REEs and magnets—an action that sent dysprosium prices soaring threefold.

The Solid Core: Where the Reporting Holds Up

It’s factual that Korea’s reliance on China for rare earth imports exceeded 80% in 2023 for metals and compounds, per the Korea Institute for International Economic Policy. It’s also correct that dysprosium is overwhelmingly controlled by China (99%+ of supply) and is critical for high-performance magnets. The reference to Vietnam’s resource base is well supported; Vietnam is among the world’s top holders of rare earth reserves, and Korean firms such as LS Cable & System are actively exploring projects there. The mention of the Korea–Vietnam Critical Minerals Supply Chain Center aligns with official joint statements from the August summit.

Foggy Edges: The Details Still Missing

While the article highlights agreements and corporate enthusiasm, it offers no production or investment timelines, resource-grade data from Vietnam, or clarity on the capacity of these projects to offset China risk in the near term. Supply chain “diversification” is presented as an established reality for major firms like Samsung and SK hynix, yet without specifying actual tonnage or import share shifts. The price spike figure for dysprosium lacks a cited baseline, making it hard to verify the true magnitude of market impact.

Framing the Narrative: Confidence or Complacency?

The tone leans toward reassurance—emphasizing that Korean giants have already diversified and face “minimal” risk from China’s dominance. That glosses over the reality that, in physical supply chains, diversification on paper doesn’t equal full insulation from price swings or geopolitical disruptions. The coverage underplays the risk of execution delays in Vietnam, where mining-to-refining capacity is still limited and infrastructure gaps persist.

Investor Takeaway

The fundamentals—Korea’s dependence on Chinese REEs, the strategic importance of dysprosium, and Vietnam’s growing role—are sound. But the optimism is ahead of the operational facts. Until Vietnamese projects prove commercial scale and quality, China remains the price and supply setter. For investors tracking the ex-China REE chain, this is a signal of intent, not yet a structural shift.
