The evolving trade negotiations between the United States and the Republic of Korea (ROK) are critical, not only for both nations but also for the wider Indo-Pacific region and the global technology landscape.
An enduring military alliance, decades of economic cooperation, and shared economic security concerns provide a robust foundation for the two countries.
In light of political shifts, a challenging U.S. tariff regime, and a shift towards protectionism in South Korea, the partnership must address mutual concerns that foster economic growth, innovation, and security.
Key areas of focus include semiconductors, shipbuilding, digital technology and connectivity, and energy and battery technology, which are crucial for both nations to achieve their respective industrial goals.
As the U.S. negotiates its supply chains and foreign policy, it must recognize that a strong collaboration with South Korea is critical to meeting its objectives and that failure to do so could have significant risks for both parties.
While South Korea’s export-oriented economy remains vulnerable, the U.S. has a keen interest in attracting investment to its Midwest and Southern states.
No matter the challenges, opportunities abound in emerging sectors, provided that trade negotiations extend beyond traditional views of trade imbalances to encompass a comprehensive bilateral partnership.
The Importance of Investment
The U.S.-ROK relationship should be approached holistically, rather than through a narrow lens focused solely on trade deficits.
By 2024, South Korea became the largest foreign investor in the United States, accounting for 2.3% of total foreign direct investment.
The Enhanced U.S. CHIPS Act and Investment Reduction Act have motivated ROK companies to commit significant investments, including a $3.87 billion project from SK Hynix to develop a semiconductor facility.
Additionally, South Korea is the second-largest destination for U.S. exports, with figures reaching $127.8 billion in the same year.
Both nations are pursuing collaborations in emerging technologies, including those related to battery technology, electric vehicles, and nuclear energy.
Key investments demonstrate this commitment, such as Hyundai’s $5.4 billion electric vehicle plant in Georgia and SK Innovation’s partnership with Ford amounting to $11.4 billion for battery parks in Kentucky and Tennessee.
Moreover, Hanwha Q Cells has invested $2.5 billion to boost its solar factory presence in Georgia, further solidifying the U.S.-ROK economic partnership.
Challenges to Enhanced Cooperation
Despite this strong foundation, there are considerable obstacles impeding greater cooperation.
According to the American Chamber of Commerce in Korea’s 2025 Business Environment Scorecard, foreign investors report challenges related to regulatory opacity, inconsistent regulatory interpretations, and sudden regulatory changes.
Additional hurdles include South Korean corporate governance issues and rigid labor policies that complicate investment flows.
The influence of major South Korean conglomerates, known as chaebols, also remains a significant point of concern, complicating the business landscape for foreign entities.
A particular focus on digital connectivity has drawn attention to Korea’s stringent regulations on cloud service providers and digital platforms that differ from international standards, impacting the free flow of data.
In 2014, the National Intelligence Service implemented additional cybersecurity requirements, limiting foreign firms’ engagement in the ROK’s public sector and underscoring vulnerabilities in cybersecurity practices.
Furthermore, newly proposed legislation aims to empower regulators to prevent anticompetitive practices among online platforms, affecting major U.S. companies such as Google, Meta, and Microsoft, as well as South Korean firms like Naver and Kakao.
Issues such as tariffs and cost-sharing complaints regarding U.S. troop presence have also strained the U.S.-ROK relationship, prompting South Korea to focus on enhancing its domestic industrial capacity.
The rising $66 billion trade deficit faced by the U.S. highlights the urgency for overcoming trade disputes and establishing equitable terms.
Given these challenges, it is vital for U.S. policymakers to showcase the substantial ROK investments in the U.S. and counterbalance trade surplus discussions to foster a more stable economic relationship.
Enhanced Cooperation on Economic Security
Despite various challenges, the mutual economic security interests shared by both nations create a pathway toward cooperation that can bolster their respective industrial and technological strengths.
In the shipbuilding sector, President Trump recently issued an executive order aimed at revitalizing U.S. commercial shipbuilding capacity, underscoring its relevance for national defense and competitiveness.
With South Korea housing the world’s second-largest shipbuilding industry, U.S. firms can strategically leverage this partnership to restore its maritime capabilities more effectively.
South Korean companies currently offer invaluable support by repairing U.S. naval vessels and collaborating with U.S. shipbuilders to construct advanced vessels that meet modern standards.
In terms of semiconductors, South Korea’s leadership in the global semiconductor market is indispensable, especially as U.S. efforts toward expanding domestic semiconductor manufacturing become a priority.
With companies like Samsung and SK Hynix leading production and investing billions to establish cutting-edge facilities in the United States, bilateral cooperation can create a robust industrial ecosystem.
Joint efforts can mitigate risks associated with China’s advancements in technology and bolster both nations’ competitiveness in emerging tech such as AI and advanced chips.
Bolstering digital connectivity is equally paramount.
The promotion of data flow and the establishment of innovative digital platforms are essential for economic growth.
However, current tariff structures and protective measures hinder fair competition for U.S. digital platforms in the South Korean market, complicating collaborative efforts in cybersecurity and digital services.
The U.S. boasts valuable expertise in cybersecurity that can immensely benefit the South Korean public and private sectors.
However, barriers exist that prevent U.S. firms from fully engaging in opportunities within ROK’s cybersecurity landscape, necessitating dialogue to harmonize standards and practices.
The two countries must deepen their energy cooperation and expand partnerships in energy technology to counterbalance China’s growing dominance in the electric vehicle market as they seek to innovate and optimize supply chains.
Collaborative efforts around small modular reactors can serve as a focal point in addressing the increasing energy needs tied to the proliferation of advanced technologies such as AI and quantum computing.
Both countries need stable and reliable energy sources to effectively respond to the ever-growing demand for electrification.
The U.S. cannot achieve its industrial and climate ambitions without significantly increasing production in sectors like batteries, solar energy, and electric vehicles.
Moreover, such partnerships pave the way for job creation in the U.S., while simultaneously insulating critical sectors from geopolitical instability.
A Path Towards Stability and Future Growth
To fully realize the potential of the U.S.-ROK relationship, trade deficits and other disagreements should not dominate the narrative.
Instead, a comprehensive understanding of the relationship that encompasses investments, contributions to job creation, and mutual benefits must take precedence.
Many U.S. companies are already embedded within the bilateral framework, and South Korean investments in the U.S. have led to significant domestic job opportunities.
Opportunities for collaboration remain ripe within sectors where both nations excel, addressing pressing economic security challenges.
South Korea’s ability to support U.S. needs in shipbuilding, semiconductor co-development, and digital platform innovation lay an invaluable proposition for both sides.
To capitalize on these opportunities, policymakers must resist zero-sum logic in favor of strategic investment that creates shared resilience.
Amending the existing Korea Free Trade Agreement to better reflect shared economic interests will further enhance this dynamic, establishing a true partnership amid global competition.
The time has come for the United States and ROK to reimagine their partnership, focusing on a collaborative future shaped by mutual growth and comprehensive economic security preparedness.
