“It is crucial that resolutions are fully enforced,” Inigo Lambertini, Italy’s deputy representative to the UN said.
“Sanctions are not the final objective. Just a means. But of course, to be effective, sanctions must be applied by everybody,” he added.
North Korea’s UN envoy last week accused the US of working to block economic development and denounced sanctions imposed on poor countries as a bid to “destroy modern civilization.”
Ambassador Ja Song Nam said North Korea will withstand the blow of sanctions and continue “along the road of building the socialist power by dint of the spirit of self-reliance and self-development.”
The latest set of sanctions were in response to Pyongyang’s sixth nuclear test — the largest yet — and the firing of two missiles over Japan.
North Korea’s main economic partner China has signed up to the measures, as has Russia.
But the US has not ruled out the use of force to compel Pyongyang to halt its missile and nuclear tests, and President Donald Trump has threatened to destroy the country.
On Saturday, he said that diplomatic efforts have consistently failed and “only one thing will work,” in what appeared to be a repetition of previous threats of force.
