South Korea to Open Sejong Presidential Office by 2029 to Curb Seoul’s Dominance

South Korea’s government announced plans to establish a presidential office in the administrative city of Sejong by August 2029, alongside the relocation of approximately 350 more public institutions from the Seoul metropolitan area. Led by President Lee Jae Myung, the initiative aims to curb the capital’s dominance and foster balanced regional development across the country.

For more than two decades, the Korean government has tried, in fits and starts, to move its center of political power away from Seoul. While the nation built a new administrative city and relocated dozens of government ministries, the president has never had a real foothold with them down south.

Here is why that matters for the country’s institutional future: President Lee Jae Myung has turned this administrative shuffle into a central pillar of his regional development agenda, signaling a concrete push to decentralize national governance before his term concludes.

Untangling Seoul’s Economic Grip

The capital region currently absorbs a share of South Korea’s population, capital, businesses, and infrastructure. Prime Minister Han Seong-sook noted that the new relocation measures form part of a broader strategy designed to tackle this concentration, especially as other parts of the country face demographic decline.

The upcoming relocations are scheduled to roll out in phases starting in 2027. According to official government statements, central government agencies will move first, prioritizing bodies with the largest scale or relocation impact.

But there is a catch. Certain powerful ministries are currently walled off by existing legal frameworks.

To pull off the broader move, the administration must amend the law governing Sejong’s development. This legislative tweak will clear the way for ministries currently excluded from relocation mandates, including the Justice Ministry and the Gender Equality Ministry. Meanwhile, the Prosecution Service and the National Police Agency will relocate only after dedicated new headquarters are completed in Sejong.

Navigating the Constitutional Ceiling

A full, permanent relocation of the South Korean presidency out of Seoul is easier said than done. Back in 2004, a Constitutional Court ruling effectively enshrined Seoul as the nation’s capital by customary law.

Because that legal barrier remains intact, President Lee has framed the Sejong project not as an outright relocation of the seat of power, but as the construction of a second presidential workplace. The idea gained momentum after Lee took office, with the State Affairs Planning Committee fast-tracking the initiative in August 2025.

After a design competition hit a brief snag over architectural symbolism and Korean identity, the government locked in a winning master plan titled “The Future We Build Together” by ANU Design Group Architects, followed by HAEAHN Architecture’s winning design for the office itself.

Alongside the executive branch, construction is marching forward on a Sejong branch of the National Assembly, scheduled for completion by 2033.

Streamlining State Bureaucracy

This massive geographic shuffle is running parallel to a sweeping internal consolidation. The government announced it will cut or restructure 109 public institutions by merging smaller bodies and consolidating overlapping functions. Notable adjustments include combining the country’s five state power generators and four port authorities.

These parallel reforms underline a dual mission: shrinking institutional bloat while physically spreading governance across the peninsula. As ground breaks in 2027 and the 2029 deadline approaches, watch to see how effectively Seoul’s entrenched political elite adapts to sharing a zip code with the nation’s administrative machinery.
