PYONGYANG, North Korea — North Korea held a major military parade and revived its iconic mass games to celebrate its 70th anniversary. But in keeping with leader Kim Jong Un’s new policies, the emphasis was firmly on building up the economy, not on nuclear weapons.

The North rolled out some of its latest tanks and marched its best-trained goose-stepping units in Sunday's parade but held back its most advanced missiles and devoted nearly half of the event to civilian efforts to build the domestic economy.

It also brought the mass games back after a five-year hiatus. The games are a grand spectacle that features nearly 20,000 people flipping placards in unison to create huge mosaics as thousands more perform gymnastics or dance in formation on the competition area of Pyongyang’s 150,000-seat May Day Stadium.
