The positive side is that the billions of dollars for these facilities will help offset some of the trade deficit from vast Chinese imports into the U.S. Also, at least until they reverse engineer the technology, the PRC will be dependent on GE for upgrades, spare parts, fuel rods, etc.
You would think so, but the last time that I looked at this deal, the U.S. taxpayer was financing it via the federal Ex-Im Bank (http://www.exim.gov/).
I don't know if that has changed, but the lead story at Ex-Im today is "Export-Import Banks of United States and China Announce Agreement to Increase Sales of U.S.-Financed Exports to China".
