South Korea's financial watchdog has announced it will intensify market monitoring and investigate potential unfair trading practices related to the takeover battle for Korea Zinc Co. This comes as the company’s shares fell more than 3% following the comments from the watchdog. The investigation is expected to scrutinize the ongoing management battle for control of Korea Zinc, which is recognized as the world's leading refiner of zinc. In a related development, MBK Partners has stated that it will not increase its tender offer price for Korea Zinc amidst this competitive landscape.
