ABSTRACT

Despite escalating domestic alarm over China’s expanding gray–zone activities in the West Sea—including fixed structures and observation buoys in the Provisional Measures Zone, navigation restrictions, and interference with Korean maritime surveys—South Korea’s executive branch has kept its response within normal politics. Applying the Copenhagen School’s securitization theory, this article investigates where the securitization process stalled despite sustained securitizing pressure from the press and the National Assembly. This article argues that while the press and National Assembly frequently made securitizing moves and occasionally demanded exceptional measures, executive discourse acknowledged security implications without publicly justifying exceptional action. Drawing on large –language–model–assisted coding of press, legislative, and executive discourse and a longitudinal reconstruction of policy documents, the study identifies an uneven configuration of facilitating conditions: the ambiguity of the gray–zone activities left room for competing interpretations of the same conduct, explicit threat framing was not joined to executive justification of exceptional measures, and security framing varied across executive institutions rather than converging on a common justification for exceptional action. The findings show how a target state can acknowledge and respond to gray–zone activities while continuing to process them through legal, diplomatic, and law–enforcement instruments. The West Sea case demonstrates that securitization can stall after threat recognition, at the point where a recognized threat would have to be joined to authoritative justification of exceptional action.
