BEIJING — North Korea's totalitarian regime Tuesday lifted the curtain slightly on plans for a successor to ailing leader Kim Jong-Il, with an announcement that his son had been named a four-star general.
However, the decision shortly before the country's biggest political conference in 30 years raised fears of possible future turmoil in the "Hermit Kingdom." The secretive government didn't say how or when the younger Kim Jong-un, thought to be 27 or 28 years old, might assume power.
Kim Jong-un's lack of experience and his junior family position as his father's third son have caused experts to worry that the transition could be rocky if the elder Kim, who had a stroke in 2008, were to die soon. Even the basic facts about Kim Jong-un remain unknown, including his birth year, his recent activities and what he looks like.
His youth is "a big problem, but there's no other choice right now," said Jiang Longfan, a professor at the Northeast Asia research institute of China's Yanbian University, not far from North Korea.
A major power struggle in North Korea would have serious implications for China and South Korea, both of which fear millions of refugees pouring across their borders. For countries beyond the region, there also would be concerns about control of the North's conventional military and nuclear program capabilities.
Kim Jung-un being the heir apparent while his father is alive is one thing, "but the question is after his father's death ... that will be the test," said Chen Qi, a professor of regional politics at Tsinghua University in Beijing.
To head off potential problems, Kim Jong-il seems to be moving his relatives and key allies into senior government positions to provide a "support base for Kim Jong-un," said Lee Jung-hoon, a professor of international relations at Seoul's Yonsei University.
Should the elder Kim die sooner rather than later, all bets could be off. "Who's to say (the allies) would continue to provide the cushion and the protection," Lee said.
Because so little is known about North Korea, though, analysts could only sift through official statements about the ruling Worker's Party conference on Tuesday, and guess what might come next. "Outside observations can to some degree be right," said Chen, the professor in Beijing. "Or maybe not."
The last similar meeting in North Korea, held in 1980, signaled that the mantle of power eventually would be passed from Kim Il-sung to his son, Kim Jong-il. That transition, however, didn't take place for another 14 years until after Kim Il-sung's heart attack.
This time, the grooming period could be much shorter due to 68-year-old Kim Jong-il's reportedly frail condition.
There's been some expectation — hedged, as with everything else about the North — that Kim Jong-un might formally be named as next in line for power.
