Given the growing need for hosts of sports mega-events to provide concrete plans for a sustainable sports mega-event at the bidding stage, it is perhaps surprising that there has not been more research on the actual implementation of the legacy plan in terms of sustainability. The main aim of this paper is to do just that: to analyse an empirical example of the implementation of the sustainability legacy plan for the PyeongChang 2018 Winter Olympic Games. Through an empirical analysis, the research methods used to collect the data are document analysis and semi-structured interviews with stakeholder sampling (16 documents and 10 interviewees). The paper uncovers the difficulties the PyeongChang Games encountered in achieving the sustainable legacy planned in the bid files through an evaluation of the implementation of PyeongChang’s legacy strategy in the context of South Korea. Part of the findings reveal that Gangwon Province and South Korea achieved their strategic goals set out in advance of the PyeongChang Olympics as an effective tool for promoting regional development. One of the main obstacles to the sustainability of the PyeongChang Olympics was the lack of a clear plan for the post-Games use of Olympics venues and conflicts of interest among stakeholders of the PyeongChang Winter Games.

This paper seeks to contribute to the growing literature on ‘soft power’ by focusing on East Asia as a region gaining in political and economic significance; equally, we highlight the role sports mega-events play in the region’s most powerful states’ soft power strategies. For the purpose of this paper, we focus on South Korea’s soft power strategy and how the hosting of major sporting events has become a central part of this. We introduce both a novel tripartite approach to the study of the motives behind hosting sports mega-events, along with new, empirical data on the chosen case of South Korea. Our findings strengthen the notion that an explanation of why states seek to host major sports events can be better understood by considering the domestic, regional and international dimensions to capture the complexities behind such decisions.
