The Soviet Union at that time lacked a widebody airliner. Development of its own Ilyushin Il-86 was delayed; consequently, in the mid-1970s, the Soviets started negotiations to buy 30 TriStars and license-produce up to 100 a year. The talks collapsed as US President Jimmy Carter made human rights an important consideration in US foreign policy. The TriStar was also listed by the Coordinating Committee as embodying advanced technology banned from potential enemies, thus being a serious obstacle to the export deal.
