Kim Jin-sun, the head of Pyeongchang's organizing committee for the 2018 Winter Olympics, resigned Monday, according to the Associated Press, via Yahoo Sports.
Jin-sun had been the head of the committee since 2011. He was elected its president shortly after the South Korean city was chosen to host the 2018 Games over bids from Munich and Annecy, France. His term was scheduled to end in Oct. 2015.
A former governor of the province which holds Pyeongchang, Jin-sun gave no clear reason for his departure.
"PyeongChang 2018 is at a turning point for the latter half of its games preparation, which requires more detailed planning and execution," Kim told a committee meeting Monday, according to a POCOG statement.
"At this critical juncture, I believe that Pyeongchang 2018 needs new leadership and a stronger system that will effectively carry out various games-related projects."
Preparations for the Pyeongchang Games are still proceeding as scheduled. IOC officials who visited the city in May expressed no major concerns about its readiness for 2018.
Pyeongchang will become the first South Korean city to host the Winter Olympics. Seoul hosted the Summer Olympics in 1988.
The 2014 Winter Olympics were hosted by Sochi, Russia.
