North Korean leader Kim Jong Un says he has "fond memories" of US President Donald Trump and is open to future talks with the United States - if he can keep his nuclear arsenal. Since the failed 2019 summit, North Korea has repeatedly said it will never give up its atomic weapons and declared itself an "irreversible" nuclear state. "We will never give up our nuclear weapons." Trump is expected to visit South Korea next month, when the country hosts the Asia-Pacific Economic Cooperation Forum (APEC) in its southern city of Gyeongju. "The timing of the remarks, just ahead of Trump's trip to South Korea for the APEC summit, appears calculated," said Lim Eul-chul at South Korea's Kyungnam University.
