North Korea's denuclearization talks with U.S. officials in Sweden have broken off shortly after they had resumed, chief North Korean negotiator Kim Nyong Gil said Saturday.

"The negotiations have not fulfilled our expectations and finally broke off," Gil told reporters outside of the North Korean embassy in Stockholm, adding that the U.S. brought nothing to the negotiating table.

The negotiations on Saturday were the first diplomatic meetings between the two countries since President Donald Trump's visit with North Korea leader Kim Jong Un at the end of June. The talks were carried out between North Korea's Gil and U.S. Special Representative for North Korea Stephen Biegun.

The talks come just days after North Korea claimed it fired off a new type of ballistic missile.

Trump and Kim have met previously in Vietnam and Singapore. Trump has wanted the country to denuclearize in exchange for reduced sanctions.

Critics, such as former National Security Advisor John Bolton, have characterized Trump's policy as appeasement and have warned that Pyongyang is stalling Washington in order to develop more nuclear weapons and missiles. Bolton said that North Korea could even sell its nuclear weapons to other countries for a profit.

Analysts have told the Wall Street Journal in July that North Korea has the capacity to develop six to seven nuclear bombs a year, with the country already having an arsenal of 20 to 60 bombs in total.
