North Korea successfully tested a hypersonic missile on Wednesday, its first major weapons test this year, said a state media report.
KCNA said it “precisely hit” a set target 700km (434 miles) away.
This is the second reported test of a hypersonic missile, which can avoid detection for longer than ballistic missiles.
The test comes as its leader Kim Jong-un had earlier vowed to bolster Pyongyang’s defences.
Mr Kim said in a New Year’s speech that Pyongyang would continue to strengthen its defence capabilities due to an increasingly unstable military environment on the Korean peninsula.
North Korea tested a variety of missiles last year amid stalled talks with the South and US.
