On 17 March 2020, Japan and South Korea announced that they would keep negotiating a trade dispute that began in July 2019, after a 16‑hour video conference – the second senior‑level dialogue between the two governments. The meeting, held online because of the COVID‑19 pandemic, focused on Tokyo’s restrictions on three materials that are vital for South Korea’s semiconductor and display‑panel sectors.
Japan’s trade ministry, represented by Yoichi Iida, head of the trade control department, said the two sides exchanged details about their export‑control systems and “welcomed the progress each side has made.” South Korea’s Ministry of Trade, Industry and Energy echoed the sentiment, noting that both governments gave “positive feedback on each other’s plan to bolster export control capabilities in terms of rules and policies.” The dispute traces back to Japan’s July 2019 decision to curb exports of fluorinated polyimides, photoresists and hydrogen fluoride – chemicals used in the production of advanced chips and flat‑panel displays.
Tokyo justified the move on national‑security grounds, alleging that Seoul mishandled sensitive shipments. Seoul, in turn, interpreted the curbs as retaliation linked to a 2018 South Korean Supreme Court ruling that ordered Japanese firms to compensate Korean workers forced into labor during World War II, a matter Japan claims was settled by the 1965 bilateral treaty. Following the export restrictions, Japan removed South Korea from its “white list” of trusted trading partners in August 2019, adding bureaucratic hurdles for a broader range of Japanese goods.
The fallout extended beyond economics: Seoul threatened to pull out of the General Security of Military Information Agreement (GSOMIA), the intelligence‑sharing pact that underpins cooperation on North Korean missile threats. The United States intervened, urging both allies to preserve the agreement.
Seoul suspended the withdrawal plan just hours before it would have taken effect in November 2019, a decision welcomed by Washington as a sign of alliance stability. The first senior‑level talks took place in Tokyo in December 2019 and lasted about six hours. While both sides described the session as constructive, no breakthrough emerged. The March 2020 meeting, twice as long, highlighted the technical and political complexity of the issue.
Both parties agreed to reconvene in South Korea, though a specific date was not set at the time of the announcement. Analysts warn that a prolonged standoff could ripple through global high‑tech supply chains.
South Korean firms such as Samsung and SK Hynix dominate the semiconductor market, while Japan supplies a sizable share of the specialized chemicals required for chip and panel fabrication. A disruption would affect products ranging from smartphones to automobiles. Domestically, the dispute carries significant political weight.
Japan’s ruling party backs the export controls as a security measure, whereas the South Korean government frames the issue as a defense of economic sovereignty. Despite the pressure, diplomatic channels have remained open, and the continuation of talks signals a mutual preference for negotiation over escalation.
The outcome of the negotiations remains uncertain, but the willingness of both capitals to stay engaged offers a modest prospect for resolution. The episode underscores how intertwined the two economies are, especially in the semiconductor supply chain, and how their broader security cooperation – particularly concerning North Korea – depends on maintaining functional diplomatic ties.
