Keeping in mind that the video image could very well bear little or no resemblance to the actual bomber, the bomber appears to be a large, cranked flying wing.

AVIC, the Chinese conglomerate, teased audiences worldwide with the first official glimpse of the country's first stealth bomber. The preview comes at the end of an eight-minute video made to celebrate the Xian Aircraft Corporation's (XAC) 60th anniversary on May 8, 2018. The giant flying wing aircraft appears shrouded in canvas inside a high tech hangar. The visual resemblance to Northrup Grumman's 2015 Super Bowl ad showing off the B-21 Raider stealth bomber is presumably deliberate. It is likely AVIC's way of proclaiming that it's arrived, fast on American heels, to the exclusive club of strategic bombers.
Cranked Wing?
Assuming the XAC anniversary video is accurate, the H-20 could be the world's first large cranked flying wing (the B-21 Raider appears to be a conventional flying wing, like the B-2).

Keeping in mind that the video image could be pure theater and bear little or no resemblance to the actual bomber, the craft appears to be a large flying wing, optimized for stealth. A bent in the leading edge of the wing suggests that the bomber, tentatively identified as the "H-20", may utilize a cranked wing design, in which the outer edges of the wings have less sweep than the blended fuselage, similar to the X-47B UAS. The fuselage bulges prominently and is expected to hold the cockpit, and air intakes for the engines.
H-20
Chinese officials have already stated their need for a strategic bomber that can at the very least, strike Hawaii and other mid Pacific targets. Noted artist Bai Wei has put together information from Chinese research articles and leaks to produce this speculative picture of the H-20 stealth bomber, which may fly by this decade.

China's willingness to promote its next-generation stealth bomber in public media is part of a wider trend in promoting new Chinese platforms like J-20 stealth fighters and aircraft carriers as part of China's growing power. While the new plane is covered in canvas, it's intended as a clear message to both domestic and international audiences.
