North Korea says it will hold talks with the US if the conditions were right.
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 said that bilateral talks between Pyongyang and Washington would be considered.
Report says North Korea would probably have to agree to at least discuss relinquishing or limiting its nuclear weapons for the US to participate.
Ms Choe, who has been involved in nuclear negotiations in the past, made the comments during a stop-over on her return to Pyongyang following a meeting in Oslo.
Mr Trump has previously said that he would like to solve the North Korea crisis diplomatically, but that a ‘major, major conflict’ is possible.
The country has engaged in several military shows of strength in recent weeks including missile tests.
The US has responded by sending warships to the region to install a controversial anti-missile system in South Korea.
