Searchina's article), 25.9% of foreign people think Samsung is a Japanese company(59.7%: a Korean Company, 10.4%: a Chinese company). Some Chinese people misunderstand it too, even though China is a neighboring country of Japan and South Korea. In China in 2012, Samsung's shop was attacked by Chinese rioters who were frustrated with JAPAN (see dongA.com's article). As said before, Samsung is a SOUTH KOREAN company.
Why do many people think Samsung is a Japanese company? There are three reasons.
