That's not a useful rate until you factor in population.
"High suicide rate" is a relative term, and does not describe foxconn.
Specifically, the baseline China rate is either 100 or 220 per million per year depending on source. Foxconn had about 14 suicides that year out of about a million workers (or about half a million at the relevant factories? I'm not exactly sure.) That's an impressively low rate. And for reference the US rate is about 100-140 per million per year.
