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, Nov. 4, Yonhap reports. Hoban Construction emerged as the top shareholder, and Hoban has notified the Fair Trade Commission of a business combination after acquiring more shares, KBS World reports. The shift has sparked uncertainty over management control, with Hanjin KAL shares surging 25.5% as the battle reignites, 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. Korean reaction focuses on the foggy outlook: Business Korea describes the direction of management rights as "descending into a fog," while noting assessments that a management dispute with Hoban has become practically slim after Cho purchased additional stakes, though Hoban is eyeing a board seat.
