Commerce Implements Controls on Advanced Semiconductor and Gas Turbine Engine

For history's sake, the prior experience of import/export controls, is that US firms use them to achieve market successes trading with what I am going to call against my better judgement "the enemy"

Exhibit A: Europeans banned from selling digital phone exchanges to USSR. IBM/Rolm get a special exclusion from the export ban, Sell digital phone exchanges to the USSR.

Not that I don't think the specific thing here (Gas Turbines for Gazprom) doesn't have some immediate relevancy, as does Gallium Arsnide power VLSI. I just observe that when its economically beneficial to the US in a trade competition (not war) with Europe or Asia, they will make releases to this rule, in the favour of a US enterprise.
