US and 10 other countries bemoan inability of UNSC to condemn repeated missile launches this year by Pyongyang as Beijing and Moscow refuse to endorse their statement.
The United States and European allies have failed to convince China and Russia in the United Nations Security Council to back a text noting North Korea's "violations" of resolutions on missile technology.
"We would love to have China and Russia join us in this room" to adopt the text, US Ambassador to the UN Linda Thomas-Greenfield told the AFP news agency on Monday after a closed-door Security Council meeting.
Backed by 10 other ambassadors –– including from countries not on the Security Council, such as Australia and Japan –– Thomas-Greenfield read out a text affirming that the group is "united today in condemning the DPRK's March 5 (local time) launch of a ballistic missile," referring to North Korea's official name, the Democratic People's Republic of Korea.
"Like the 10 other ballistic missile launches since the beginning of the year, this act by the DPRK violated multiple Security Council resolutions," she said.
"While the DPRK escalates its destabilizing actions, the Security Council continues to remain silent.
"Each ballistic missile launch that results in inaction by the Council erodes the credibility of the UN Security Council itself," Thomas-Greenfield added, without mentioning China or Russia.
The two countries were the only states opposed to the short, "basic" text at Monday's meeting, diplomats said.
North Korean state media said Pyongyang carried out a test on Saturday for what it said was a reconnaissance satellite, but which analysts said was a thinly veiled ballistic missile launch, just days before a presidential election in South Korea.
China opposes text for 17th time
The text said the Security Council had met, that there were "violations" of the Council's resolutions and called for dialogue, a diplomat told AFP on the condition of anonymity.
The meeting marks the 17th time China has opposed the adoption of a US- and European-proposed text against North Korea since 2017 when the Security Council unanimously adopted sanctions in an effort to force Pyongyang to halt its nuclear and ballistic missile programmes.
"We stand ready to collaborate and determine a mutually agreeable approach with other Council Members to address the DPRK's provocations," Thomas-Greenfield said.
"But let us start with the basic premise that the Council has a responsibility to speak publicly about clear and repeated violations of Security Council resolutions," she added, calling on other members to also condemn "these dangerous and unlawful acts."
Despite biting international sanctions over its nuclear weapons, Pyongyang has ignored US offers of talks since high-profile negotiations between leader Kim Jong-un and then-US president Donald Trump collapsed in 2019, which Thomas-Greenfield pointed out on Monday.
Instead of diplomacy, Pyongyang has doubled down on Kim's drive to modernise its military, warning in January that it could abandon a self-imposed moratorium on testing long-range missiles and nuclear weapons.
