Ask what Korea is talking about.

Hoban Group has become the largest shareholder of Hanjin KAL, the holding company of Korean Air, overtaking Hanjin Group Chairman Cho Won-tae and his related parties, according to a regulatory filing on Wednesday, Yonhap reports. Hoban Construction emerged as the top shareholder, and Hoban has notified the Fair Trade Commission of a business combination after securing more shares, KBS World reports. The shift has reignited uncertainty over management control, with Hanjin KAL shares soaring 25.5% as Hoban's stake threatens Cho's position, Business Korea reports. Korean Air said it cannot confirm whether Hoban has overtaken Cho, citing a lack of information on the scale of stakes, the Korea Times reports. Business Korea notes assessments that a management dispute had become slim after Cho purchased additional stakes, but Hoban is now pushing for a board seat.
