North Korea has published a commentary in state-run media strongly objecting to the resolution passed by a UN agency against Pyongyang's missile launches. It says it is looking at carrying out future firing without prior notification.

Korean Central News Agency published the commentary by an expert on international affairs on Sunday.

It denounces the resolution adopted by the International Maritime Organization, or IMO, as being in line with anti-North Korea hostile policies of the United States and its followers.

The UN agency is tasked with overseeing the safety and security of maritime shipping. It adopted its first-ever resolution last Wednesday condemning Pyongyang following its recent repeated missile launches.

The commentary says the resolution is taken as a public announcement that the IMO no longer needs notification from North Koreans on plans to launch satellites.

The commentary says that last time North Korea notified Japan on the planned launch based on IMO rules.

Last month, North Korea said its attempt to put a military reconnaissance satellite into orbit failed, and it would conduct another launch soon. The move is raising concerns for the US, Japan and South Korea.
