If that's true, it's not the first time GM has made that noise.
In the last several years, they've told a number of suppliers that GM will NO LONGER work with suppliers that did not have an offshore mfg. facility (at that time, they would accept Mexican plants.)
The supplier could maintain a US plant, but had to have another, someplace offshore.
If GM is now mandating PRChina, it's no surprise--even the Mexicans won't work for 25 cents/hour.
They can come to the US, illegally, and get $5--$9.50 in the veggie fields, slaughterhouses, or construction/landscaping.
