It's not easy to find in MSM, but this from WoS February 10, 2012...
"Johann Lamont had chosen the new Forth Bridge as her line of attack, and angrily demanded to know why filthy foreigners (in this case, the Chinese) had been awarded what she called an "£800m steel contract" to produce the materials for the crossing. Salmond explained that no such thing had happened, noting that the steel accounted for only 5-10% of the sum quoted and that there were no Scottish companies industrially capable producing the type of steel that would be provided by the Chinese. The actual value of that element of the contract, he pointed out, was somewhere between £20m and £60m, rather than the £800m Lamont had claimed.
Lamont wasn't to be deflected by anything so basic and trivial as being utterly wrong. She reasserted that the Scottish Government was "spending £800m on steel" and that "not a single job has been created in Scotland" as a result. Salmond got back to his feet, admonished Lamont for not listening to the previous answer, and added that procurement rules cited by the previous Labour FM Jack McConnell meant that contracts couldn't simply be given to Scottish companies regardless of other tenders.
But it was to no avail, as she ignored the points and rambled on at enervating length about how dastardly foreign workers were profiting from Scotland's bridge before Salmond comprehensively reiterated the hard facts – Lamont's numbers were wildly wrong to the point of comedy (perhaps Andy Kerr had done her research), not a single Scottish steel fabrication company had tendered to supply the core steel for the bridge because there WERE no Scottish steel fabrication companies, and that all contracts had by law to be awarded competitively."
Emphasis mine. The use of Chinese steel has nothing to do with redundancies in Glasgow.
