An emergency meeting of the UN Security Council to discuss the recent firing of a missile by North Korea has been postponed.
North Korea said on Wednesday that it had carried out the first test-launch the previous day of a newly developed hypersonic missile, the Hwasong-8.
The UNSC was set to meet on Thursday at the request of the United States, Britain and France.
Diplomatic sources said China expressed reluctance about holding the session. China is a permanent member of the council.
The meeting is now being rescheduled for Friday.
The council held an emergency meeting following North Korea's launches of short-range ballistic missiles on September 15. It failed to agree on a united response, as the views of the US and some European countries differed from those of China and Russia.
The postponement of Thursday's session has highlighted the lack of agreement among the council members on the issue.
