North Korean leader Kim Jong-un, smiling broadly and supporting himself with a cane, appeared Tuesday in state media for the first time in nearly six weeks, ending an absence that fed global speculation that something was amiss with the country's most powerful person.

The sudden resumption of the "field guidance" tours that had been a regular part of Kim's public persona before he stopped showing up in media reports for 40 days allowed the country's massive propaganda apparatus to continue doing what it does best — glorifying the third generation of Kim family rule. And it will tamp down, at least for the moment, rampant rumours of a coup and serious health problems.

Kim, while touring the newly built Wisong Scientists Residential District and another new institute in Pyongyang, "took necessary steps with loving care," a dispatch early Tuesday from the official Korean Central News Agency said in typical fawning style. The North didn't say when the visit happened, nor did it address the leader's health.

The recent absence was, in part, "probably an attention-getting device and it certainly works," Bruce Cumings, an expert on Korea at the University of Chicago, said in an email.

All this puts them back on the front page."

Before Tuesday's dispatch, Kim had last been seen publicly at a Sept. 3 concert.

Foreign media had no trouble filling the void that followed. From Saturday Night Live spoofs to the wild theories of journalists across the globe trying to parse his growing absence from the public eye, Kim captured nearly as many headlines as he did when he threatened to nuke his enemies last year.

This ability to command attention by doing nothing says a lot about the North's propaganda focus on Kim as the centre of everything. Remove for 40 days the sun around which that propaganda spins and the international media, both traditional and social, exploded with curiosity.

And while there was plenty of informed analysis from experts and frequent visitors to Pyongyang that said it probably wasn't anything that serious, there seemed to be even more thinly sourced speculation.

Kim was, by turns, reported to be suffering from gout, from diabetes, from a brain hemorrhage, from a heart ailment, from a leg injury that required surgery from a French doctor, from mental illness or, according to a head-turning British report, from a cheese addiction. There were rumours of a coup.

Diplomacy has continued in Kim's absence

The speculation was partly a result of Kim missing several high-profile events that he normally attends and his description in an official documentary last month as experiencing "discomfort." Archive footage from August showed him overweight and limping.

The South Korean government, however, saw no signs to indicate any major problems.

At a South Korean parliamentary hearing Monday, Choi Yoon-hee, head of the Joint Chiefs of Staff, told a lawmaker that whatever health problems Kim might have, they "are not severe enough to disrupt his status as the ruler of the country."

No unusual troop movements or other signs of a possible coup have emerged. Diplomacy at the highest level has continued: Three members of his inner circle made a surprise visit to the South, something analysts say would be impossible without the leader's blessing. Foreign tourists and aid workers are still travelling to the North, and there have been no reports of new restrictions or warnings for diplomats.

There's also nothing particularly unusual about North Korean leaders laying low for extended periods. Kim's grandfather, Kim Il-sung, and father, Kim Jong-il, both took long, unexplained breaks from work, often leading to similar rumours in Seoul and beyond of coups and sudden death. Kim Jong-un, who seems to genuinely like being at the centre of things, took off without a word for three weeks in 2012.

Part of the interest in Kim's absence also stemmed from worries about what would happen to the country if the leader died without securing a succession.

Kim Jong-un's two older brothers, for whatever reasons, were deemed unfit to rule by Kim Jong-il, and little is known about Kim Jong-un's sister.

Kim reportedly does have a direct heir who may one day extend the Kim dynasty into a fourth generation. Probably not soon, though. She's believed to be a toddler.
