Page 159 from FCO 372113 - the Nuclear policy of Pakistan 1978

The letter expresses concerns about the proposal to subject inverters to export control. While preventing the spread of sensitive technology is important, there are difficulties with implementing the proposal. Inverters have various industrial applications beyond nuclear purposes, and controlling their export would require extensive decision-making and information about end-use. Inverters are also produced in several countries, and if potential suppliers refuse to deliver to Pakistan, it may only cause a delay rather than prevent proliferation. The effectiveness of using export control in this case is questioned, as it could lead to refusals and contract breaches without achieving the intended objective. The author welcomes a discussion on the matter. Copies of the letter are sent to other relevant individuals.
