SEOUL — North Korea on Wednesday test-fired a submarine-launched missile 500km towards Japan, which Japan said marked the first time a North Korean sub-launched missile had entered its air defence identification zone. "This system is still in development, but North Korea is clearly making progress," Lewis said. Current UN resolutions prohibit North Korea from any use of ballistic missile technology, but Pyongyang has continued to carry out numerous launches following its fourth nuclear test in January. Trilateral talksMeanwhile, foreign ministers from Japan, China and South Korea held their first talks in more than a year today just hours after the North Korea missile launch. The meeting, the first since March 2015, comes as Tokyo, Seoul and Beijing have struggled to find common ground on how to deal with North Korea.
