“East” and “West” have long been prominent categories in the history of technology. The historical literature that claims to deal with comparisons or connections between East and West from a technological point of view is rich and fascinating. Yet, so far there has been no attempt to succinctly summarize or synthesize the main findings. This article takes a first step towards such a synthesis. It does so by addressing technological interaction between three broadly defined geographical regions: Western Europe and North (...) America; Eastern Europe, Russia and Central Asia; and the non-Russian Far East. The article suggests that East–West studies in the history of technology can be divided into three sets, which would benefit from greater interaction with each other: studies of East–West and West– East technology transfer; studies comparing the evolution of Eastern and Western technological levels and technological “styles”; and studies of large technical systems that materially interconnect East and West.
