On 28 February 1953, Joseph Stalin endowed China with 10 Tu-4 heavy bombers. These Tu-4's were refitted with AI-20K turboprop engines in 1966. In 1967 China attempted to develop its first airborne early warning aircraft, based on the Tu-4 airframe. The project was named KJ-1 and mounted a Type 843 rotordome on top of the aircraft. However, the radar and equipment was too heavy, and the KJ-1 did not meet PLAAF's requirements. The project was canceled in 1971. The last PLAAF Tu-4 were retired in 1988.

This version shown in this photocope has been refitted with Ivchenko AI-20 turboprop engines by China (using either original Soviet engines or the Chinese licence-production version, dubbed the WJ6). They probably provided improved performance compared to the Tu-4's original Shvetsov ASh-73 radial engines (themselves a further development of a license-built version of the US Wright R-1820 Cyclone 9 that powered the B-17 Flying Fortress).
