Taiwan designates Korea as Namhan; warns ETA changes if no response by March 31
Taiwan’s Ministry of Foreign Affairs said on the 1st that the designation for Korea on Taiwan’s foreign-resident card has been changed to “Namhan” (South Korea), in line with the principle of equal footing between the two sides. It added that if Korea does not respond positively by March 31, Taiwan will take corresponding measures against Taiwan’s Electronic Travel Authorization (ETA) program.
The move comes amid a dispute over how Korea labels Taiwan in its immigration-related forms. Taiwan objects to Korea’s practice of listing Taiwan as “China (Taiwan)” or otherwise tying Taiwan to China on the departure and destination fields of Korea’s ETA.
Taiwan’s foreign ministry stressed that Koreas and Taiwan have long-standing economic, cultural, and people-to-people exchanges, and that Taiwan values that relationship. It urged Korea to rectify the “unfair” labeling on Korea’s ETA and to engage constructively.

Taiwan had publicly raised the issue again last December. President Tsai Ing-wen has said she hopes Koreas can work together to advance regional peace, stability, and prosperity. Taiwan’s Deputy Minister of Foreign Affairs, Chiang Ming-chi, noted that Korea maintains a large trade surplus with Taiwan and argued that unfriendly actions would be inappropriate.
A Korean foreign ministry official said Seoul is reviewing the matter, considering various factors, and that this is not a new issue. The ministry indicated it would handle the situation according to Korea’s fundamental stance.

Taiwan’s side also cited the broader international backdrop, including the One China principle emphasized by Beijing’s Taiwan Affairs Office as a basic norm of international relations.
For U.S. readers, the dispute highlights how Taiwan’s international status and cross-strait dynamics can intersect with practical issues such as travel, trade, and supply chains. Taiwan is a critical supplier of semiconductors and other advanced electronics, and Korea is a major technology player in its own right; together, friction over how Taiwan is labeled in immigration and travel documents can ripple into business travel, regulatory coordination, and regional security alignments that touch U.S. interests in Asia.
Context for non-Korean readers: Taoyuan International Airport in Taiwan is a major international hub, underscoring how its travelers interact with Korea’s immigration systems. The case centers on how national designations are used in bilateral administrative forms and what happens when states object to those designations in ways that affect travel and visa processes.
