North Korean state media have raised the possibility that the isolated country could "establish a new relationship" with the United States.
It comes a day before North Korean leader Kim Jong-un meets US President Donald Trump for historic talks.
The comments mark a shift in tone from North Korea after decades of animosity towards the US.
Meanwhile Mr Trump has said he has a "good feeling" about the much-anticipated summit.
Both leaders arrived for the talks - the first ever between a sitting US president and a North Korean leader - in Singapore on Sunday.
Mr Trump tweeted on Monday morning that there was "excitement in the air" in the Asian country ahead of the summit.
He hopes the meeting will kick-start a process that eventually sees Mr Kim give up nuclear weapons. But North Korea's perspective has always been more opaque.
