South Korea has proposed talks with North Korea to avoid border clashes. It is first such offer in seven years, as Seoul moves to ease military tensions with the nuclear-armed North. "The South Korean military formally proposes to hold military talks with North Korea to discuss setting a baseline for the military demarcation line to prevent accidental clashes between the two Koreas and ease military tensions," Kim Hong-cheol, South Korea's Deputy Defence Minister for National Defence Policy, said in a televised statement. Despite decades of intermittent dialogue, the two Koreas remain technically at war, since the 1953 armistice that halted the Korean War was never followed by a formal peace treaty.
