U.S. President Donald Trump has announced that his second summit with North Korean leader Kim Jong Un will be held in the Vietnamese capital of Hanoi at the end of this month as the two sides seek to inject fresh momentum into denuclearization talks.
During the Diet committee session, Foreign Minister Taro Kono said he is arranging a meeting with U.S. Secretary of State Mike Pompeo before the upcoming U.S.
The US wants North Korea to make a full declaration of all its nuclear weapons facilities and commit to destroying them, under global supervision - something North Korea has never said it will do. Palladino reiterated that sanctions relief that North Korea has been seeking would follow its denuclearization. He said the history of the two nations reflects the possibilities for peace and prosperity.
Palladino said Vietnam is a close friend and partner of the United States.
It remains unclear how long the talks will continue.
The State Department confirmed Biegun agreed to meet his North Korean counterpart Kim Hyok Chol again before the summit.
Stephen Biegun, the US special representative for North Korea, met with South Korean Foreign Minister Kang Kyung-wha and Seoul's chief nuclear envoy Lee Do-hoon on Saturday to brief them on his negotiations with North Korea.
They are likely to cover a wide range of subjects but focus on concrete denuclearization steps the North will take and the US response, as well as protocol and security at the summit scheduled for February 27-28 in Vietnam. He and Biegun have stressed the economic benefits to North Korea if it does so.
Before travelling to Pyongyang on Wednesday, Mr Biegun said he wanted to achieve some "concrete deliverables". "I look forward to seeing Chairman Kim & advancing the cause of peace!"
The United States sustained more than 33,000 battle deaths in the Korean War, while the number of NKoreans killed, both military and civilian, has been estimated at about 1-M.
In a report earlier this week, it said actions including the illegal transfer of banned goods at sea could make sanctions - the worldwide community's main way of putting pressure on North Korea - "ineffective".
It said the country's nuclear and ballistic missile programs remained intact and North Korea was working to make sure those capabilities could not be destroyed by any military strikes.
