The People's Republic of China received over 250 Soviet built Il-28s from 1952, and when the Sino-Soviet split occurred in the late 1950s, it decided to place the Il-28 into production, despite no manufacturing license being obtained. Chinese built aircraft differed from the original Soviet aircraft in that they have a redesigned wing structure, abandoning the horizontal manufacturing break, saving at the cost of more difficult construction. Chinese aircraft also used a different tail turret based on that of the Tupolev Tu-16, and fitted with faster firing AM-23 cannon.
