The US has denied that its day of nuclear talks with North Korea ended in failure, insisting that “good discussions” were had.
Earlier, North Korea said the meeting had broken down, because the US brought “nothing to the negotiation table”.
Officials from the two countries met in Sweden on Saturday, in the hope of breaking their stalemate.
This came just days after North Korea tested a new missile, in a significant advance on earlier tests.
The meeting was the first formal working-level discussion since US President Donald Trump and North Korean leader Kim Jong Un met briefly at the inter-Korean border zone in June.
Neither of the leaders was present in Sweden, instead initial discussions were being handled by North Korea’s Kim Myong Gil and US Special Representative for North Korea Stephen Biegun.
They met on an island northeast of Stockholm called Lidingo, where North Korea has its embassy.
