This fleshes things out a bit:
If Ms Kim does go to Seoul in March, it would be the first time an immediate member of the Kim dynasty has travelled to South Korea.
Ms Kim, who is believed to be 26, has risen rapidly in the regime in recent months and was in late November confirmed as a senior official in the ruling Workers Party.
Her rise has coincided with the purging and reported execution of dozens of senior government officials and Ms Kim now apparently serves as her brothers most trusted advisor
Isn’t March during the U.S./South Korea war games? What an odd time to go because usually the tension is very high during that period.
