Japan's rearmament plans noted, S. Korea's Yun Byung-se says SEOUL, Oct. 14 (UPI) -- Japan's move toward rearmament and expansion of its self-defense-only military force will not be overlooked, South Korea's foreign minister said Monday. There are many countries, including us, that are worried about Japan's rearmament. A situation where [they] overlook Japan's rearmament will not come," said Yun Byung-se, South Korean foreign minister, in reference to the right-wing government in Japan moving to rewrite its pacifist constitution to expand the capability of its forces. Japan's constitution, written by the United States in 1947 after Japan's World War II surrender, limits its military to self-defense and bans it from using force in international disputes. Yun noted the approval of U.S. Secretary of State John Kerry and Defense Secretary Chuck Hagel, who agreed with their Japanese counterparts to modernize Japan's military in a meeting earlier in October, should not be interpreted as U.S. approval of any decision by Tokyo to rearm, the South Korean Yonhap News Agency reported. "It means that [a military build-up plan] will be pursued within the scope of the U.S.-Japan security treaty, rather than that the U.S. will give Japan a blank check," Yun said.
