The South Korean allegedly built a chip factory in China to manufacture copied Samsung chips.
South Korean police have arrested two former Samsung executives suspected of leaking Samsung secrets worth $3.2 billion to China. The authorities reported that one of the arrested suspects, 66-year-old Mr. Choi, set up a joint venture building chips in China alongside some local officials and served as its CEO (via Bloomberg). He was allegedly assisted by a plant designer, Mr. Oh, in this venture, while he also attempted to recruit other South Korean experts to work for him.
Look at Samsung's history. This is their MO, it's how they became the Samsung we know today - straight up steal actual product designs, not just concepts, not just copy closely, a compete steal, and sell until arrested.
