South Korean President Moon Jae-in, who met with Trump on Thursday and addressed the U.N. General Assembly, said sanctions were needed to bring Pyongyang to the negotiating table and force it to give up its nuclear weapons, but Seoul was not seeking North Korea's collapse.
The situation on the Korean peninsula is getting more serious by the day and can not be allowed to spin out of control, Chinese Foreign Minister Wang Yi told his German counterpart, the state-run China News Service said this morning. Previous quakes were caused by weapon tests. Pyongyang later said it had tested a hydrogen bomb that could be fitted onto a missile-an assertion that no foreign government has so far confirmed.
The administration said in a statement on its website that the quake, which occurred around 4.29pm, was recorded a depth of 0km.
The agency said it was analysing the nature of the quake and its initial view was that it was a natural tremor because no sound waves specific to man-made earthquakes were detected.
Resisting intensifying worldwide pressure, Pyongyang conducted its sixth and largest nuclear test on September 3 and has launched several missiles this year, including two intercontinental ballistic missiles.
The majority of North Korea's oil likely comes from China, but the exact tally of oil exports remains unknown, as Beijing has not published such data since 2014.
A Friday commentary from the North's official Korean Central News Agency accused the party newspaper People's Daily and other party news outlets of "kowtowing to the ignorant acts of the Trump Administration".
North Korea has one nuclear test site - Punggye-ri. Its leaders say nuclear capabilities are its only deterrent against an outside world seeking to destroy it.
European Union ambassadors have reached an initial agreement to impose more economic sanctions on North Korea, going beyond the latest round of United Nations measures, officials and diplomats said.
The pair had swapped insults, with Mr Trump calling the North Korean a suicidal "rocket man" and being labelled "mentally deranged" and "a dotard" in return.
His comments came after Trump ordered new sanctions on individuals, companies and banks doing business with North Korea as he sought to further isolate the regime and increase economic pressure for it to curb its weapons programs.
