North Korea has rejected any further talks with South Korea, calling its decision “completely the fault of South Korea’s actions”.
It issued a statement in response to a speech by South Korea President Moon Jae-in on Thursday.
South Korea’s president, Moon Jae-in, vowed to achieve the unification of the Korean peninsula by 2045, a century after the end of the second world war.
In a speech to mark the 74th anniversary on Thursday of Korea’s liberation from Japan’s 1910-45 rule, Moon also said South Korea would “gladly join” hands with its former colonial ruler to defuse an escalating trade dispute whose roots lie in the country’s bitter wartime history.
Meanwhile, early on Friday North Korea test-fired two missiles into the sea off its eastern coast, the South Korean military said.
It is the sixth such test in less than a month.
Six days ago, North Korea fired two short-range ballistic missiles into the Sea of Japan.
The series of tests come after US President Donald Trump and North Korean leader Kim Jong-un agreed during a meeting in June to restart denuclearisation negotiations.
