North Korea has said it will hold talks with the US “if the conditions were right”, South Korean media reports.
A senior North Korean diplomat said dialogue with the Trump administration was possible following a meeting with ex-US government officials in Norway.
Earlier this month US President Donald Trump said he would be “honoured” to meet Kim Jong-un.
The comments follow months of rising tensions over North Korea’s ballistic missile and nuclear programme.
Choe Son-hui, an official in the North Korean foreign ministry responsible for North American affairs, told reporters in Beijing that bilateral talks between Pyongyang and Washington would be considered.
