Before June 13, 1978: A: Q. Khan Network Conducts Procurement Operations in Japan
The A. Q. Khan network that is attempting to build a nuclear weapon for Pakistan conducts procurement operations in Japan. The existence of the Japanese activities will be revealed in a letter from Khan to a correspondent, the Canada-based scientist A. A. Khan, dated June 13, 1978 and later obtained by Canadian authorities. Although a substantial amount of information is available about some of Khan’s operations in other countries, little is known about what he purchases in Japan. [Levy and Scott-Clark, 2007, pp. 53]
