Coupang Inc. founder and chairman Kim Bom-suk, also known as Bom Kim, has notified the National Assembly that he will not attend a two-day parliamentary hearing on the company scheduled for this week.

Rep. Choi Min-hee, chair of the National Assembly's Science, ICT, Broadcasting and Communications Committee, disclosed Kim's notice of absence in a Facebook post on Sunday, calling his refusal to appear "absolutely unacceptable."

In the notice, Kim said he is currently residing overseas and would be unable to attend due to prior commitments on those dates, adding that the schedule had already been finalized and could not be changed.

Former Coupang CEO Kang Han-seung and Coupang Vice President Kim Yoo-seok, the younger brother of Kim Beom-seok, who were also summoned as witnesses, submitted similar notices saying they would not attend.

Choi rejected the explanations, criticizing Coupang's leadership for prioritizing other engagements over what she described as serious issues facing the company in South Korea, and vowed that the National Assembly would continue with its responsibilities.

The joint hearing, led by the ruling Democratic Party and involving six parliamentary standing committees, is scheduled for Tuesday and Wednesday.
