SINGAPORE, June 3 (Reuters) - South Korea's defence minister said on Saturday that some countries were "ignoring North Korea's unlawful behaviour", which he said threatens to weaken U.N. sanctions against its missile and nuclear programmes.
On Wednesday, North Korea launched its first spy satellite into space, although it ended in failure with the booster and payload plunging into the sea.
The South Korean minister reiterated that coordination with the United States and Japan to deter North Korea was important.
The three countries have agreed to begin sharing North Korean missile warning data in real time "within this year", South Korea's defence ministry said in a statement after a meeting between the South Korean, U.S. and Japanese defence chiefs.
North Korea argues it has a sovereign right to space development.
