PYONGYANG, North Korea (AP) – North Korea is holding what is expected to be one of its biggest celebrations ever Saturday for the 70th anniversary of its ruling party's creation, an attention-getting event that is the government's way of showing the world and its own people the Kim dynasty – now in its third generation – is firmly in control and its military a power to be reckoned with.

As the clock struck midnight Friday, North Korean leader Kim Jong Un marked the anniversary by paying respect to both his late father and grandfather at the Kumsusan Palace of the Sun in Pyongyang, according to the North's official Korean Central News Agency, or KCNA.

The military parade kicking off the celebrations could hold some surprises for analysts abroad who will be watching its display of weaponry very closely, particularly North Korea's growing fleet of drone aircraft and long-range missiles.

The guest list is shaping up to be less impressive. 

While no world leaders will be attending – North Korean ally China is sending a senior Communist Party official, not its head of state, or even vice premier – the normally isolated and quiet North Korean capital has been flooded by tourists, international media and delegations ranging from ethnic Koreans living abroad to obscure Russian and Mongolian groups dedicated to studying North Korea's political ideas.

The military parade was expected to begin in the morning, but was being delayed, apparently due to heavy rain Friday night. Even by late morning, as a light rain fell, officials had not distributed a final schedule – which is unusual even in North Korea.

Suggesting that the show will indeed go on, crowds of people carrying bouquets of plastic flowers could be seen streaming to Kim Il Sung Square, where the event will be held. Military vehicles or possibly floats shrouded in blue plastic tarps to protect them against the weather were parked in a long row on a bridge leading to the parade route.

Even though North Korean officials did not divulge details of the day's plans, open-source satellite imagery has been monitoring large-scale troop activities at the Mirim military air base in Pyongyang, which has been rigged with a mock-up of Kim Il Sung Square. Masses of Pyongyang citizens have for weeks been out in public plazas across the city practicing their roles for a torchlight parade in the evening.

For the finale, a stage has been set up on a river running through central Pyongyang for a late-night concert featuring North Korea's most popular musical group, the all-female Moranbong Band. Tickets for foreigners hoping to attend the concert were going for 100 euros ($114) a pop.

The spectacle promises to be the most elaborate since Kim Jong Un assumed power after the death of his father, Kim Jong Il, in late 2011, and the satellite imagery suggests the military parade could be the country's biggest ever.

It's not known if Kim himself will speak at any of the day's events.

Kim has yet to make a state visit abroad and although his visits to various farms and factories around the country are featured daily on North Korean news broadcasts, he rarely speaks at public events.

Though military parades were out of fashion until about a decade ago, North Korea's leadership often uses anniversaries to rally the nation behind the military or the party, while at the same time reinforcing the primacy of the leader himself.

On Friday, senior state officials led a mass gathering in Pyongyang singing the praises of the party and the leader.

Also on Friday, Kim met with the Chinese delegation led by Liu Yunshan, the Communist Party's No. 5 leader, where Liu delivered a message by Chinese President Xi Jinping, KCNA said.

China's official Xinhua News Agency reported that Liu told Kim that China was willing to work with North Korea for a quick resumption of six-party nuclear talks. The talks, which aim to end the North's nuclear program and also involve the U.S., South Korea, Russia and Japan, stalled seven years ago.

Some foreign analysts believe the particularly strong emphasis this year on making the anniversary of the party's foundation such a lavish fete is a sign that Kim is trying to build up his own stature along with that of the party relative to the military.

Though Kim's leadership and both institutions are strong, the power balance among various government organs in North Korea is a delicate one and maintaining that balance is a key to keeping Kim's regime solid and unchallenged.

North Korea maintains its ``military-first policy,'' which it says is necessary to counter threats from South Korea and the United States, but officials have recently stressed the role of the party in improving the standard of living for the people, who are increasingly aware of how far they lag behind their affluent cousins south of the Demilitarized Zone and in economic giant China.

In the run-up to this year's anniversary, large-scale construction and development projects have been launched and hailed with great fanfare in the state media.

The projects include new hydropower plants and high-rise apartments, but it is unclear how much of North Korea's limited financial resources have been put into improving the lot of the majority of its citizens who are not fortunate enough to live in the relatively developed and affluent capital.
