Japan Removes South Korea from 'White List,' Escalating Trade Dispute William Gallo Updated on Aug. 2, at 2:32 a.m. SEOUL -- Japan has removed South Korea from a list of its preferred trading partners, a major escalation in a trade dispute rooted in historical tensions. The Cabinet of Shinzo Abe, Japan's conservative prime minister, Friday approved plans to remove South Korea from the list of so-called "white countries" with preferred trade status. Beginning Aug.28, Japanese companies must now seek case-by-case approval from Japan's trade ministry before shipping certain products, which could be diverted for military use, to South Korea. South Korean President Moon Jae-in called the move "selfish" and a "grave challenge" to Korean-Japan relations, warning it could damage the global economy. Earlier, a South Korean presidential Blue House spokesperson vowed a "resolute" response. Japan last month restricted exports of high-tech materials to South Korea. The materials are used to produce semiconductors and displays in smartphones and other electronics that serve as the backbone of South Korea's export-driven economy. .
