South Korea's financial watchdog is continuing its investigation into Korea Zinc Co. following the company's decision to cancel a planned $1.8 billion share sale. The share sale, announced nearly two weeks prior, had sparked a significant selloff in the company's stock and raised concerns that led to the regulatory probe. Korea Zinc's board is scheduled to meet on Wednesday to discuss future strategies amidst this controversy. Additionally, South Korea has imposed fines on Barclays and Citi for naked short selling, further emphasizing the regulatory scrutiny in the financial sector.
