North Korea may consider attending an inter-Korean summit if mutual respect can be guaranteed, according to state news agency KCNA, citing Kim Yo Jong, North Korean leader Kim Jong Un’s sister.

The remark comes only a day after North Korea requested the US and South Korea to stop their “hostile policies” and “double standards” toward it before official negotiations on ending the 1950-53 Korean War could take place.

There was a cease-fire, but no peace treaty, at the end of that battle.

“I believe only when fairness and mutual respect can be maintained can smooth communication between the North and the South take place and … issues such as summit meetings between the North and South can be resolved,” Kim said in a statement.

South Korea President Moon Jae-in repeated a call for a formal end to the war in an address to the U.N. General Assembly in New York on Tuesday.
