China and Russia have placed a "hold" on the proposal by the U.S. to impose new UN sanctions on the regime.
Washington unilaterally imposed sanctions against North Korean individuals and entities in response to the regime's recent missile launches.
It then proposed that five of those individuals should also be subject to UN travel bans and have their assets frozen.
But a proposal of this nature requires approval from all 15 members of the UN Security Council and China said it needed more time to study it, while Russia said more evidence is needed.
This came ahead of a UN Security Council meeting on North Korea, held behind closed-doors later in the day.
But seven council members, and Japan issued a joint statement at the United Nations, urging the Security Council to respond to the North's threats by implementing sanctions, calling the regime's moves "unlawful."
"These facts should not be in dispute. The DPRK's unlawful behavior is a threat to international peace and security. It is extremely important that member states take the necessary steps to implement the sanctions in their jurisdictions or risk providing a blank check for the DPRK regime to advance a weapons program."
North Korea has carried out four missile launches this year, all of which were in violation of UN Security Council resolutions.
The regime has also suggested that it will resume nuclear and inter-continental ballistic missile testing.
Citing an official from the office of the White House National Security Council's spokesperson, state broadcaster Voice of America reported Thursday, that the NSC remains prepared to engage in "serious and sustained diplomacy" with North Korea without preconditions to make tangible progress.
The official added that while the NSC remains committed to diplomacy, it will continue to work with the international community to halt progress in North Korea's ballistic missile programs.
