North Korea said on Tuesday the United States must accept that reality has changed since the countries' summit meetings in the past, and no future dialogue would end its nuclear program, state media KCNA reported.

In a statement carried by state media, Kim Yo Jong said she doesn’t deny the personal relationship between her brother and Trump “is not bad.” But she said if their personal relations are to serve the purpose of North Korea’s denuclearization, North Korea would view it as “nothing but a mockery.”

The country appeared to signal an openness to talks, but said it must be recognized as a nuclear power and would not discuss abandoning its arsenal.
