Under President Moon Jae-in, South Korea has set an ambitious target to move from being “first in the world” in the race to 5G to “first in global quality.” Yet, while a range of industry and government stakeholders are investing heavily in making this vision a reality, a number of factors are likely to weigh on whether or not these efforts yield significant results. These include uncertainties about how to further accelerate development in ways that lead to better returns on investments, and about how to navigate complex geopolitical considerations, including ongoing debates about Huawei’s involvement in 5G network infrastructure. Each of these areas will, in turn, require domestic stakeholders to make complex assessments about potential tradeoffs and risks. Thus, this paper assesses South Korea’s emerging 5G era at the one-year mark, and highlights key successes, setbacks, and ongoing challenges. Building on these findings, the paper concludes by offering several potential scenarios for future development, and suggestions for ways forward.
