SEOUL, South Korea (AP) — North Korean leader Kim Jong Un’s daughter made a public appearance again, this time with missile scientists and more honorific titles as her father’s “most beloved” or “precious” child. She’s only about 10, but her new, bold photos are deepening the debate over whether she’s being primed as a successor.

The daughter, believed to be Kim’s second child named Ju Ae and about 9 or 10 years old, was first unveiled to the outside world last weekend in state media photos showing her observing the North’s intercontinental ballistic missile launch the previous day with her parents and other older officials. The daughter wearing a white puffy coat and red shoes was shown walking hand-in-hand with Kim past a huge missile loaded on a launch truck and watching a soaring weapon.

On Sunday, the North’s official Korean Central News Agency mentioned her for the second time, saying she and Kim took group photos with scientists, officials and others involved in what it called the test-launch of its Hwasong-17 ICBM.

KCNA described her as Kim’s “most beloved” or “precious” child, a more honorific title than her previous description of “(Kim’s) beloved” child on its Nov. 19 dispatch. State media-released photos showed the daughter in a long, black coat holding her father’s arm as the two posed for a photo. Taking after her mother Ri Sol Ju, who wasn’t visible in any of the photos Sunday, she had a more mature appearance than in her unveiling a week ago.
