The linking of the DPRK to the already sunk ship is groundless and the reason for Japan to do so is to mislead public opinion, a Foreign Ministry spokesman was quoted by the official Korean Central News Agency as saying.
"This is an unpardonable smear campaign against the dignified DPRK," the spokesman was cited as saying.
He noted that some days ago, Japan used force to sink a ship in other country's territorial waters with the mobilization of patrol boats and planes under the pretext of chasing an "unidentified ship."
The spokesman stressed that no matter what details of the incident were, Japan's open military action committed beyond its territorial waters proves that Japan's moves for remilitarization and overseas expansion have reached a very perilous phase.
The DPRK is compelled to maintain the highest degree of vigilance against a series of plots hatched by Japan to escalate its anti-DPRK campaign, and will take relevant countermeasures depending on the future attitude of Japan toward the incident, the spokesman added.
