From Critical Minerals to Connectivity: South Korea’s Stakes in Central Asia
On September 16, Seoul hosted the first Korea–Central Asia Summit, bringing President Lee Jae Myung together with the heads of all five Central Asian states. The meeting elevated a dialogue that has run at a ministerial level since 2007 to the level of heads of state. The leaders adopted a Seoul Declaration setting the terms for future engagement and agreed to hold summits every two years. On September 14, trade and industry ministers from South Korea and the five Central Asian states met in Seoul for the first C5+Korea Industry Ministers’ Meeting. They signed a joint statement launching a standing platform for industrial cooperation. Uzbekistan’s Ministry of Investment, Industry and Trade used the occasion to push for a shift away from raw-material trade toward joint production and localization. Behind the diplomatic choreography sits a practical problem: the minerals both sides keep discussing cannot move without a route to carry them. A Minerals Agenda with Separate Tracks South Korea relies heavily on imported minerals for its manufacturing industries. Seoul has been developing separate plans with each country. With Tajikistan, discussions have focused on gold and silver, alongside antimony. With Kyrgyzstan, Seoul has been discussing antimony and tungsten. Cooperation with Uzbekistan covers minerals and digital manufacturing. With Kazakhstan, a central issue is moving beyond raw exports toward processing inside the country, as The Times of Central Asia reported ahead of the summit. South Korean firms are pursuing supply diversification independently. POSCO International and LX International have been expanding overseas mineral investments, including graphite and nickel projects, amid Chinese export restrictions. The Transport Connection Consider the Bolashak chrome mine in Kazakhstan, which Eurasian Resources Group launched in late 2024. The company plans to ramp it up to a design capacity of 7.5 million metric tons of chrome ore a year. Production on that scale makes reliable transport an essential part of the commercial equation. An Atlantic Council analysis identifies limited processing capacity and underdeveloped westward routes as obstacles to U.S. mineral partnerships with Central Asia. It presents the Trans-Caspian Middle Corridor as a route to Western markets that avoids Russian and Iranian territory. That argument needs a distinction when applied to Korea. The corridor runs westward toward Europe; it is not a prerequisite for minerals to reach South Korea. Its relevance is the wider choice of buyers it could offer Central Asian producers, including potential Korean-backed processing ventures serving those markets. That corridor is being built out. The Aktau container hub has a planned capacity of 240,000 twenty-foot equivalent units. The World Bank-backed Mointy–Kyzylzhar railway is meant to remove a 149-kilometer detour and accommodate 30 train pairs a day, against roughly ten on the existing constrained route. Traffic is already rising: 125 container trains crossed Kazakhstan on the Trans-Caspian route in the first quarter of 2026, up 34.4% year-on-year. Japan has also become involved, pledging in August 2025 to help modernize customs operations at the port of Aktau. The Seoul Declaration also backs Korean participation in transport infrastructure, including modernization and digitalization. In...
