Last year, IBM sold their per­sonal com­puter busi­ness to a Chi­nese firm. And now…

WASHINGTON (Reuters) – The State Depart­ment, react­ing to secu­rity con­cerns after its pur­chase of com­put­ers from a Chi­nese com­pany, will not use the equip­ment for clas­si­fied infor­ma­tion, an aide to Vir­ginia Repub­li­can Rep. Frank Wolf said on Thursday.

In March, the State Depart­ment said it had pur­chased a batch of com­put­ers from China’s Lenovo Group Ltd..

The gov­ern­ment is going to have a hard time keep­ing up this level of cau­tion. Per­haps 95% of lap­top com­put­ers on the mar­ket today, for exam­ple, are made in China. (The rest are made in Penang, Malaysia.) Desk­top machines are assem­bled all over the world, but with a con­sid­er­able num­ber of Chi­nese com­po­nents. There are no “Amer­i­can” com­puter man­u­fac­tur­ers left.
