Korea-Mexico Summit: Implications of Resuming FTA Negotiations and Expanding Cooperation in Critical Minerals, Defense, and AI
Executive Summary
President Lee Jae-myung's state visit has brought Korea-Mexico FTA negotiations back to the table for the first time in 20 years. Mexico is already a USMCA-based export hub to the United States, home to over 500 Korean companies. The newly signed Joint Action Plan represents an attempt to fill the institutional void—such as the lack of investment protection and social security agreements—that has persisted despite the substantial scale of bilateral economic relations. The fact that the Sheinbaum administration has incentives to diversify its partners amid US pressure over triangular trade and tightened investment screening provides a favorable negotiating environment for Korea. However, expanding cooperation in critical minerals, crude oil, defense, and AI risks remaining merely symbolic; for these efforts to translate into actual contracts, working-level FTA negotiations must proceed alongside domestic coordination regarding agricultural market opening. Given Mexico's moves to diversify its approach toward China, Korea needs to expedite the establishment of an institutional framework to secure its position as a key third-party partner.
I. Issue Analysis
Korea-Mexico Summit: Issue Analysis
1. Background and Progress
Discussions on a free trade agreement (FTA) between Korea and Mexico began in the early 2000s. Since then, they have remained stagnant for over 20 years without any substantial progress [3]. Although the two countries officially declared the resumption of negotiations in 2022 [1], the negotiating table has not been properly reconvened since then.
Mexico is integrated into the United States-Mexico-Canada Agreement (USMCA, known as T-MEC in Mexico) framework and positions itself as a core pillar of the North American supply chain. Within this structure, Korean companies have already established a significant presence in Mexico. Currently, approximately 500 Korean companies operate in the country [1][3]. This is the result of automakers and electronics firms, such as Samsung, LG, and Kia, utilizing Mexico as a low-tariff export hub to the United States.
The problem is that despite the scale of these practical economic relations, there has been no institutional framework to support them. Due to the absence of an FTA, basic mechanisms such as investment protection and social security agreements have not been established for 20 years [1][3]. This is the context behind President Lee Jae-myung's remark during an interview during his state visit, where he noted that 'it is time to establish an institutional framework commensurate with the relations we have built so far' [1].
The external environment surrounding Mexico has also changed rapidly of late. The Sheinbaum administration faces US pressure over allegations of triangular trade and demands for tightened investment screening [4]. Washington has raised concerns over Chinese capital entering the US market by bypassing through Mexico [4]. Discussions on revising Mexico's National Foreign Investment Commission (CNIE) are also underway in tandem with this pressure [4]. Under these circumstances, the Mexican government has an incentive to diversify its supply chain partners and move away from its heavy reliance on the United States.
2. Current Situation
President Lee Jae-myung made a three-day state visit to Mexico starting September 23, marking the first state visit by a South Korean president to Mexico in 16 years [6]. During the summit with President Sheinbaum, the two countries signed the 'Korea-Mexico Joint Action Plan 2026-2030' [5]. This plan explicitly expands the scope of cooperation to include crude oil, critical minerals, defense, and artificial intelligence [5].
In an interview with the local daily El Universal, President Lee defined Mexico as 'Korea's largest trading and investment partner in Latin America' [3]. He presented three major tasks: resuming negotiations on economic agreements, signing a social security agreement, and strengthening investment protection mechanisms [1][3]. At the subsequent Korea-Mexico Business Forum, he once again called for the swift resumption of FTA negotiations [7].
At this juncture, the attention of the local Mexican media is focused more on Mexico's diplomatic moves toward China than on expanding cooperation with Korea. El Financiero prominently reported that President Sheinbaum expressed 'interest' in holding a bilateral meeting with President Xi Jinping on the sidelines of the APEC summit in November [11]. This aligns with the Mexican government's efforts to diversify its diplomatic counterweights in response to US pressure over triangular trade. The adoption of the Joint Action Plan with Korea can also be read as a branch of this diversification trend.
3. Key Actors and Positions
Mexican Government (Sheinbaum Administration): Amid US pressure regarding investment screening and tariffs, Mexico needs partners to diversify its supply chain. Korean manufacturing investment has a track record of making substantial contributions to job creation and industrial advancement [1]. At the same time, Mexico must operate within the constraints of complying with USMCA rules of origin. It is attempting a balanced diplomacy that manages both its approach toward China and its cooperation with Korea [11].
Korean Government: President Lee defined Mexico as an 'important partner in electric vehicles and defense' [1]. The government has a clear, practical goal of filling the legal protection gap for the 500 Korean companies operating there through institutionalization. Cooperation in crude oil and critical minerals is significant for supply chain diversification, while cooperation in defense and AI is meaningful for regional diversification that goes beyond US-centric security cooperation [5].
United States (Background Variable): Although not a direct party, the United States is in a position to effectively regulate the scope of Mexico's external cooperation through the USMCA framework and pressure to tighten investment screening [4]. Even if a Korea-Mexico FTA is actually concluded, it is already constrained by the fact that it cannot escape the rules of origin and the monitoring network against triangular trade.
4. Key Issues
The first issue is the gap between the declaration to resume FTA negotiations and the actual conclusion of an agreement. A similar declaration of resumption was made in 2022, but no progress was made for four years [1]. It remains unconfirmed whether the current declaration will lead to the activation of a working-level negotiation track.
The second is the issue of alignment with USMCA rules of origin. Most investments by Korean companies in Mexico are predicated on exporting to the United States. The practical key is whether a Korea-Mexico FTA can be integrated with this structure without conflict.
The third is Korea's position within Mexico's balanced diplomacy between China and the United States. In a situation where the Sheinbaum administration's move to pursue a meeting with Xi Jinping [11] and US pressure on investment screening [4] are occurring simultaneously, what strategic implications expanding cooperation with Korea holds for Mexico is a question that will unfold during the future negotiation process.
II. In-Depth Analysis
Korea-Mexico Summit: In-Depth Analysis
1. Root Cause Analysis
The root cause of the Korea-Mexico FTA drifting for 20 years lies in the strategic priorities of both sides rather than the difficulty of the negotiating agenda itself. Since the 2000s, Mexico has effectively centered its foreign trade policy on the North American Free Trade Agreement (NAFTA) and its successor, the USMCA. While a customs union-like integration with the United States and Canada was a constant in its economic policy, individual FTAs with Asian countries were treated as secondary issues. Korea, too, concentrated its negotiating resources on concluding FTAs with the United States and the EU after the mid-2000s, pushing negotiations with Mexico down its priority list.
Domestic political burdens surrounding agricultural market opening have also dampened negotiating momentum. Mexico remains a society with a high proportion of the workforce employed in primary industries, such as corn and sugar. The structure is one where Korea must make corresponding concessions in agriculture and livestock in exchange for gaining access to the Mexican market in the automotive and electronics sectors. This asymmetrical interest has raised the cost of domestic persuasion for both sides, making it difficult for negotiations to progress on their own when political priority was low.
The lack of substantial progress even after the 2022 declaration to resume negotiations was also due to overlapping domestic political schedules in both countries following the pandemic. Korea went through a transition of power and a presidential impeachment crisis, while Mexico underwent its 2024 presidential election and the inauguration of the Sheinbaum administration. Agendas like trade negotiations, which require long-term working-level accumulation, are easily sidelined amid the uncertainty of political schedules [1][3].
2. Structural Context
Economic Structure: Mexico has functioned as an export platform to the United States utilizing USMCA rules of origin. Approximately 500 Korean companies are already integrated into this structure and operate local production bases [1][3]. The problem is the gap between this economic reality and the legal-institutional framework. In the absence of an FTA, an investment protection agreement, and a social security agreement, companies have essentially continued their expansion while bearing the risks themselves. President Lee's remark that 'it is time to establish an institutional framework commensurate with the relations we have built so far' targets this structural delay [1].
Security and Trade Structure: The external environment facing the Sheinbaum administration is different from the past. Washington is pressing for tightened investment screening based on allegations of Chinese capital bypassing through Mexico [4]. Discussions on refining the screening criteria of Mexico's National Foreign Investment Commission (CNIE) strongly reflect a response to this pressure [4]. At the same time, President Sheinbaum expressed interest in a bilateral meeting with President Xi Jinping on the sidelines of the APEC summit in November [11]. This represents a dual approach of maintaining reliance on the United States while attempting to diversify diplomatic and trade partners. The adoption of the Joint Action Plan with Korea aligns with Mexico's interest in securing a third-party partner—neither the United States nor China—amid this diversification trend.
Political Structure: The Mexican presidency is limited to a single six-year term with no re-election. Consequently, policy continuity tends to fluctuate significantly with transitions of power. While the previous L3pez Obrador administration was passive toward overseas travel, President Sheinbaum is evaluated as being relatively open to foreign visits [11]. There are indications that these differences in leadership style have directly influenced whether trade negotiations are resumed.
3. Comparison of Historical Precedents and Similar Cases
The Korea-Chile FTA (which entered into force in 2004) was Korea's first FTA. Despite intense domestic opposition over agricultural market opening, it was eventually concluded. This case differs from Mexico in that the negotiating partner was not part of an exclusive economic bloc with the United States. Because Mexico belongs to the USMCA, a separate and powerful trade bloc, any FTA with Korea is constrained by the fact that it can only be effective to the extent that it does not conflict with the rules of origin within that bloc.
The negotiation process of the Korea-US FTA (which entered into force in 2012) is also a reference precedent. It took more than five years from the start of negotiations to entry into force, during which it underwent transitions of power and renegotiation phases. The tendency for trade negotiations to be subordinate to the domestic political schedules of both countries is similarly observed in the Korea-Mexico case. However, in the case of Korea and Mexico, the degree of delay is far more severe, given that negotiations themselves have effectively been in a state of suspension for 20 years.
Japan's approach to Mexico also serves as a point of comparison. Japan put the Japan-Mexico Economic Partnership Agreement (EPA) into effect back in 2005. Through this agreement, Japanese companies secured tariff benefits and investment protection mechanisms in Mexico ahead of Korea. The fact that Korean companies have expanded into Mexico on a large scale even without an FTA paradoxically indicates that they prioritized market accessibility and geographical advantages despite bearing this institutional void. At the same time, this means that the institutional disadvantages of Korean companies compared to their Japanese counterparts have continued to accumulate.
4. Key Variables Shaping Future Developments
USMCA Joint Review Schedule: A joint review of the USMCA is scheduled for 2026 [4]. If rules of origin are tightened during this process, the very viability of Mexico as a production base for Korean companies could be shaken. Discussions on resuming FTA negotiations can hardly proceed independently of the outcome of this USMCA review.
Intensity of US-Mexico Pressure over Triangular Trade: The intensity with which the United States challenges Mexico's connections with China will dictate the Mexican government's incentives to diversify. If this pressure eases, Mexico's momentum to pursue an FTA with Korea could also weaken [4].
Political Reaction of Mexico's Domestic Agricultural Sector: If negotiations are actually launched, domestic interest groups surrounding sensitive items such as corn and sugar are likely to push back once again. This was one of the core reasons negotiations failed to progress over the past 20 years.
Policy Consistency of the Sheinbaum Administration during Its Term: Under a single six-year term system, the key is whether initial policy priorities can be sustained through the latter half of the administration. For the Joint Action Plan 2026-2030 to transition into an actual implementation phase, a continuous commitment to push forward from the Mexican bureaucracy is a prerequisite [5].
III. Recommended Policy Responses
Korea-Mexico Summit: Comprehensive Responses and Action Plans
1. Comprehensive Assessment and Recommended Responses
Mexico holds a position beyond that of a mere emerging market in Korea's trade strategy toward Latin America. It is a country where approximately 500 Korean companies have already entered and established substantial production bases [1][3]. Its function as an export hub to bypass the United States using USMCA rules of origin is structured such that its strategic value actually increases as US trade pressure on Korea intensifies. The problem is that the legal and institutional framework to support these practical economic relations has been absent for 20 years [1][3]. While the adoption of the Joint Action Plan is an attempt to fill this void, the FTA negotiations themselves remain at the stage of a mere declaration of resumption.
Changes in the external environment surrounding Mexico present both opportunities and risks for Korea. The phase in which the Sheinbaum administration seeks to diversify its diplomatic and trade partners in response to US pressure over triangular trade provides a favorable negotiating environment for Korea [4][11]. At the same time, Mexico's moves to tighten foreign investment screening (CNIE) could affect the investment and procurement structures of Korean companies in Mexico [4]. The fact that President Sheinbaum expressed interest in a bilateral meeting with President Xi Jinping can be read as a signal that Mexico needs a third-party partner—neither the United States nor China [11]. Korea has a strong incentive to preemptively secure this position.
Expanding cooperation into critical minerals, crude oil, defense, and AI carries significant symbolic weight [5]. However, the fact remains that an institutional infrastructure like an FTA is required for these efforts to translate into actual contracts and investments. The task for the next stage is to convert the political momentum generated at the summit level into driving force for working-level negotiations.
2. Short-, Medium-, and Long-Term Action Plans
Short-Term (3–6 Months)
The Ministry of Trade, Industry and Energy (MOTIE) must reactivate the working-level FTA negotiation channels that have been stagnant since the 2022 declaration [1][3]. Among the negotiating agendas, priority should be given to conducting preliminary coordination with domestic stakeholders regarding agricultural market opening. If this coordination is delayed, negotiations are highly likely to drift again, sidelined by political schedules as in the past.
For the four areas specified in the Joint Action Plan—critical minerals, crude oil, defense, and AI—working-level groups should be established at an early stage to finalize a list of concrete projects [5]. Given the long contract lead times in the defense sector, clarifying target items and procedures during the initial phase would be highly advantageous.
A channel for continuous monitoring of Mexico's discussions on revising the CNIE screening criteria should be established, centered on KOTRA and the South Korean Embassy in Mexico [4]. A communication channel is needed to convey the concerns of South Korean companies before the detailed revised criteria are finalized.
Medium-term (6 months to 2 years)
It is realistic to pursue FTA negotiations in parallel with an investment protection agreement and a social security agreement [1][3]. Addressing these three agreements simultaneously rather than sequentially can reduce the risk of the entire negotiation process drifting again over the long term. The social security agreement, which is less politically sensitive, can be utilized as a track for early conclusion.
Cooperation on critical minerals needs to be materialized in the form of long-term supply contracts to diversify raw material sourcing. Cooperation on crude oil should also progress beyond simple purchasing to exploring possibilities for joint investment in refining and logistics infrastructure [5].
In a context where Mexico's rapprochement with China and US pressure on investment screening are occurring simultaneously, South Korean companies must manage regulatory risks by refining their proof-of-origin compliance systems and dual sourcing networks to avoid exposure [4].
Long-term (2 years or more)
On the premise of the FTA entering into force, the goal should be to elevate South Korea-Mexico relations to the most institutionalized relationship among non-USMCA partners. This will yield practical benefits for South Korean companies by securing an alternative hub if US trade pressure on South Korea or demands for supply chain restructuring intensify in the future.
AI cooperation needs to expand beyond the initial stage of intergovernmental cooperation to pilot projects between companies of both countries. Concrete projects combining Mexico's manufacturing base and South Korea's AI and semiconductor capabilities must emerge at this stage to validate the substance of the cooperation.
3. Monitoring Indicators and Trigger Points
The initiation of working-level FTA negotiations and the pace of negotiation rounds should serve as the primary indicators. If a schedule for working-level negotiations is not set within six months of signing the Joint Action Plan, it can be interpreted as a recurrence of past patterns of drifting.
The timing of the finalization of Mexico's CNIE amendment and the details of its criteria serve as immediate trigger points [4]. If the amendment proves to be effectively targeting Chinese capital, the possibility cannot be ruled out that the burden on South Korean companies to prove origin and ownership structures will also increase.
Whether a Sheinbaum-Xi Jinping summit takes place and its outcomes will serve as indicators to gauge the direction of Mexico's external balancing strategy [11]. If the summit actually occurs and economic cooperation agendas emerge, South Korea must reassess its relative position within this diversification trend.
Changes in the intensity of US tariff and investment screening measures against Mexico also require continuous observation [4]. While intensifying pressure from Washington increases Mexico's incentive to diversify its partners, it simultaneously raises the risk for South Korean companies using Mexico as a base for circumvention exports to the United States.
4. Summary and Conclusion
Although Mexico is a substantive economic partner where 500 South Korean companies have already taken root, the legal and institutional framework to support this has remained in a vacuum for 20 years [1][3]. The recent Joint Action Plan and the call to resume FTA negotiations are political signals aimed at filling this gap [5], and tangible results depend on the pace of future working-level negotiations. The current situation, in which Mexico seeks to diversify its partners amid US pressure on investment screening [4][11], provides a favorable negotiating environment for South Korea, but this window of opportunity is limited. If the momentum at the leadership level is not translated into working-level achievements, South Korea-Mexico relations are highly likely to remain confined to symbolic declarations once again.
