TOKYO (Sputnik) — It is expected that the channel, dubbed Link-16, will be controlled from the US military base in Osan, south of Seoul, according to the Yonhap news agency.
"Despite the U.S.-Japan linkage, information sharing will not take place without the agreement from each side and, even if it takes place, it will be confined to subjects on North Korea's nuclear weapons and missiles," a defense official was quoted as saying by the agency.
South and North Korea are still legally at war, as no peace treaty between them was signed after the Korean War of 1950-1953.
Long-standing tensions between the two Koreas flared up again in late August when cross-border artillery fire erupted along the Demilitarized Zone, prompting Pyongyang to declare what it described as a "semi-state of war." The two countries eventually defused the tensions during a series of talks.
Relations between the two countries further deteriorated when Pyongyang claimed it had carried out a hydrogen bomb test earlier this month.
