SEOUL, Jan 5 (Reuters) - Private equity giant Carlyle Group (CG.O) bought a 10% stake in logistics company Hyundai Glovis Co Ltd (086280.KS) worth about 611 billion won ($510 million), Hyundai Motor Group said on Wednesday. The shares in the Hyundai Motor (005380.KS) affiliate were sold by Hyundai Motor Group Chairman Euisun Chung and Honorary Chairman Mong-Koo Chung, Hyundai Glovis said in a regulatory filing. Mong-Koo Chung and Euisun Chung are father and son. "Carlyle’s deep sector expertise and strong operational value-creation capabilities will benefit the corporate value and the shareholder value of Hyundai Glovis going forward," the group said in a statement. Carlyle did not immediately respond to a request for comment. South Korea recently strengthened its antitrust regulations against listed companies with more than 20% held by owner families, down from a 30% stake. ($1 = 1,198.1300 won)
