At around 9:50 am Saturday, President Yoon officially appointed Han Duck-soo as the nation's new Prime Minister, 48 days after being tapped by the South Korean leader for the post.
His nomination was approved on Friday with a 208-to-36 vote after the main opposition Democratic Party, which holds a majority at the National Assembly, decided to give the green light.
The PM is the only Cabinet post that requires parliamentary approval.
Han vowed to do his best to serve the president and run a country that prioritizes national interests and the people.
He also pledged to actively push for deregulation, the recovery of financial soundness, and national unity.
The 72-year-old is no stranger to the job, as he served as PM during the liberal Roh Moo-hyun administration.
Han has also worked in various government posts and played a key role in the FTA negotiations with the U.S.
