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".
Thanks for the news and the link.
