I am here because I want denuclearisation: Kim

North Korean Leader speaks on denuclearisation, Kim and Trump held a summit in Vietnam.

Hanoi: North Korean leader Kim Jong Un says he wouldn't be holding a second summit with US President Donald Trump if he weren't willing to make good on his denuclearisation pledge.

Asked by a US reporter on Thursday in Hanoi whether he's willing to denuclearise, Kim responded: "If I'm not willing to do that, I won't be here right now."

Trump told reporters that that's what the two are discussing during their second day of talks.

Kim was also asked if the leaders would be talking about human rights, which he's accused of abusing. But Trump responded to the question instead, telling reporters: "We're discussing everything."

In an unprecedented question-and-answer session with reporters in Vietnam, the two leaders of the technically-warring countries also inched closer toward establishing formal ties.

Trump said it's "a good idea" for the US to open a liaison office in North Korea.

Asked by an American reporter if he was willing to allow the US to open an office in Pyongyang, Kim said through a translator, "I think that is something which is welcomable."

Trump says that he considers it "a good idea," adding that it should happen "both ways".
