The improvement of inter-Korean relations is a foreign policy priority of the administration of South Korean President Moon Jae-in. The dynamics of the dialogue between the Korean states will be influenced by internal, especially economic, problems in South Korea, progress in the U.S.–North Korea talks on denuclearisation, and coordination within the U.S.–South Korea alliance. Weakening public support and problems in the alliance may make it difficult for Moon to achieve the main goals of his inter-Korean policy. The EU can play a role in maintaining the North-South dialogue by providing more support for conciliatory measures from the Moon administration.
