The publication androidheadlines.com is reporting that, according to an unnamed source in South Korea's Trade Commission, Qualcomm is under investigation by that country. This was first reported by Maeil Business Newspaper of South Korea. The investigation is reportedly about Qualcomm's potential abuse of its dominant position as the top mobile chip maker.
On February 10, Qualcomm agreed to pay China $975 million, the largest fine in China's history, over antitrust issues related to China's 2008 anti-monopoly law. The fine ended a 14-month-long investigation, and Qualcomm's stock rose as the uncertainty evaporated. The agreement also required Qualcomm to lower its royalty rates on patents used in China, according to Reuters.
One of the risks of settling an antitrust matter with one country is that another country will follow suit. Qualcomm had no comment on the matter.
