On Thursday (22), Seoul took over a cleaver to form pact with Tokyo in terms of military intelligence, sharing ties shifting the damage into the military space, foreign reports said.
The long-running and rather savagely bitter bilateral dispute over recent history apparently has taken its latest escalation.
The pact, in Northeast Asia, was the only official tie binding the military bodies of Seoul and Tokyo, according to reports.
The Northeast Asia is a global flash point of critical economic and strategic importance, where China, North Korea and Russia face off against Japan, South Korea and the United States.
Tokyo has already expressed their displeasure over the actions by Seoul, according to reports. However, no reaction from the US has yet officially been reported.
