The US says its discussions with North Korea are moving “more quickly than expected” ahead of the joint summit in Singapore on Tuesday.
The preliminary talks between officials have been taking place ahead of the highly anticipated first meeting.
The White House also confirms that President Donald Trump and Kim Jong-un will hold a one-on-one meeting, with only translators present, adding that Trump will then leave the country that same evening.
Earlier, North Korean state media talked about a “new relationship” with the US.
The US also said it will offer North Korea “unique” security assurances in return for denuclearisation, according to Secretary of State Mike Pompeo.
He insisted the US would accept nothing less than complete denuclearisation.
