"The United States calls on all member states to fully implement the existing Security Council resolutions," US Ambassador to the United Nations Linda Thomas-Greenfield said during the meeting convened to discuss North Korea.
"Because of DPRK's increasingly dangerous provocations, the United States will be introducing a... Security Council resolution to update and strengthen the sanctions regime" that was adopted in December 2017, she said, using the official acronym for North Korea.
At the time "the council decided we would take further action in the event of a DPRK ICBM launch," Thomas-Greenfield said.
"This is precisely what happened. So now is the time to take that action."
The unanimously adopted text was voted on a month after Pyongyang fired its last previous intercontinental ballistic missile (ICBM), the Hwasong-15, which was deemed powerful enough to reach the continental United States.
Following Friday's meeting, a group of 15 nations including permanent Security Council members Britain, France and the US -- but minus China and Russia -- released a joint statement condemning Pyongyang's latest launch "in the strongest terms" and warning it "poses a threat" to the entire international community.
"The DPRK is demonstrating its determination to continue advancing its weapons program as it escalates its provocative behavior -- and yet the Council has remained silent," said the countries, which include non-permanent Security Council members Brazil, Ireland and Norway, as well as Germany, Japan and South Korea.
The statement urged UN states, especially Security Council members, "to join us in condemning this behavior and in urging the DPRK to abandon its weapons of mass destruction and ballistic missile programs and engage in diplomacy toward denuclearization."
China addressed the Security Council meeting and urged "prudence and reason" regarding North Korea.
"All is not quiet on the international front. No parties should take any action that would lead to greater tensions," China's UN ambassador Zhang Jun said.
Russia, for its part, warned against following Washington's lead on tightening sanctions.
Deputy Russian envoy to the UN Anna Evstigneeva said Moscow believes that doing so would "go beyond the framework of cutting off financing" for the DPRK missile and nuclear programs and would "threaten North Korean citizens with unacceptable socio-economic and humanitarian problems."
