The battle surrounding control of Korea Zinc has increasingly evolved far beyond a traditional shareholder dispute and now stretches into Washington, Tokyo, and the broader geopolitical competition over critical mineral supply chains. In recent months, MBK Partners and its ally Young Poong expanded their campaign against Korea Zinc by hiring major U.S. lobbying and legal firms connected to discussions surrounding the company’s critical minerals refinery project in Tennessee, a project closely aligned with American efforts to reduce dependence on China for strategic mineral processing and industrial supply chains.
According to lobbying disclosures and Korean media reports, the MBK-Young Poong alliance retained the global law firm, which also performs lobbying -Squire Patton Boggs – through a special purpose entity called Korea Corporate Investment Holdings (KCIH). The filings specifically referenced “foreign investment in a critical mineral refinery in Tennessee,” directly tying the lobbying effort to Korea Zinc’s growing U.S. expansion strategy. Reports indicated the campaign focused on shareholder rights, foreign investment oversight, and corporate governance issues connected to the ongoing struggle for influence over Korea Zinc.
The decision to bring in one of Washington’s most connected lobbying organizations demonstrated how much larger the Korea Zinc shareholding conflict has become. Squire Patton Boggs maintains extensive ties across Congress, trade policy circles, and federal regulatory institutions, particularly in sectors involving manufacturing, industrial policy, and cross-border investment. Multiple lobbyists were reportedly assigned to the account as the dispute expanded beyond South Korea’s corporate sector and into strategic minerals policy discussions in the United States.
The timing is particularly notable because Korea Zinc’s Tennessee refinery project has been repeatedly positioned by American officials and industry observers as strategically important to U.S. supply chain resilience. The project is tied to broader efforts aimed at securing domestic and allied refining capacity for minerals essential to semiconductors, electric vehicles, advanced manufacturing, and defense systems. As competition over critical minerals intensifies globally, the Korea Zinc dispute has increasingly become intertwined with wider geopolitical and industrial policy considerations.
Critics of MBK Partners have also increasingly pointed toward the firm’s historical financial relationships involving Chinese state-linked capital and investors connected to Chinese state-owned enterprises (SOEs). These concerns have become more sensitive as Washington places greater scrutiny on foreign influence, strategic mineral supply chains, and potential direct links to entities aligned with the Chinese Communist Party (CCP). Within this context, some industry observers view MBK’s expanding lobbying campaign in Washington not simply as a shareholder rights effort, but also as part of a broader attempt to reposition itself politically and soften growing concerns surrounding its own geopolitical exposure.
The issue carries particular weight because Korea Zinc’s Tennessee refinery project sits within a sector now viewed by the United States as strategically critical to national industrial and economic security. Any perception of indirect CCP-linked influence surrounding ownership disputes or governance instability could complicate political support, regulatory confidence, or long-term strategic partnerships tied to the refinery. Rather than Korea Zinc itself being viewed as the primary geopolitical liability, critics increasingly argue that MBK’s own historical ties to Chinese state-linked capital risk becoming the larger vulnerability capable of undermining confidence in the project among U.S. policymakers and strategic stakeholders.
At the same time, MBK Partners continues managing mounting financial pressure connected to Homeplus, one of the firm’s largest and most controversial investments. Homeplus entered court-led rehabilitation proceedings following severe debt and liquidity problems, triggering criticism of MBK’s leveraged buyout model and long-term management strategy. Korean media reports stated that MBK has since decided to sell off portions of the Homeplus business and related assets as part of broader restructuring efforts aimed at stabilizing the retailer’s financial position amid ongoing creditor pressure.
MBK also faced complications earlier this year in Japan after authorities intervened in the firm’s proposed acquisition of Makino Milling Machine. The transaction became politically sensitive because Makino’s advanced machine tool technologies were viewed as strategically important to industrial and defense manufacturing capabilities. The move reflected a broader trend across Asia in which governments are increasingly willing to scrutinize or block foreign investment transactions involving sensitive industrial technologies and strategic manufacturing infrastructure.
The Korea Zinc conflict now sits at the intersection of shareholder activism, industrial policy, strategic minerals, and national economic security. What began as a domestic corporate struggle has evolved into a much larger contest involving Washington lobbying firms, international legal battles, geopolitical supply chain competition, and growing government attention toward strategically important industries across the United States and Asia.
