A N.Korean MiG-21 Crashed In China
Possibly a deserter. The locals at the crash site revealed on the internet that there was one man rescued by medical people. The aircraft was in rather good shape (it didn't explode), hinting insufficient fuel being the cause of crash. People at my forum have identified it as a MiG-21PF/PFM (see image).

North Korea obtained about 180 MiG-21s, including the MiG-21F-13, the MiG-21PF/PFM, and the MiG-21U/UM. Surprisingly, despite the country's close ties with China, North Korea doesn't seem to have obtained any F-7s. North Korean MiG-21s remain in first-line service.

The pilot, who was reportedly the only person onboard the plane, was killed in the incident.
