North Korean state TV aired a 50-minute documentary on Saturday about Kim Jong Un’s trip to China to attend a military parade, highlighting the leader’s bilateral talks with Vladimir Putin and Xi Jinping and giving domestic viewers a rare glimpse of Beijing’s advanced weapons development.

The Korean Central Television (KCTV) program also revealed that Kim stayed at the DPRK Embassy in Beijing during his three-day, two-night visit, suggesting he chose the safety of the North Korean facility instead of a state guesthouse due to concerns over his security.
