North Korea said on Friday it would soon check whether it could access the funds, which account for about $25m.
“It is time now for the DPRK to make its move so that all of us can move forward,” the US state department said in a written statement, referring to the country by its official name, the Democratic People’s Republic of Korea.
The statement also said North Korea must immediately invite back International Atomic Energy Agency nuclear inspectors and begin shutting down Yongbyon to get energy aid promised under the February 13 deal.
Sean McCormack, the state department spokesman, said in the statement: “It remains for the DPRK Korea to realise fully its commitments … by inviting back the IAEA immediately to begin shutting and sealing the Yongbyon nuclear facility.”
McCormack said that would allow other nations to provide North Korea with the equivalent of 50,000 tonnes of heavy fuel oil, as promised under the agreement among the two Koreas, China, Japan, Russia and the US.
