"Except for the fact that China has been helping Iran, North Korea and was helping Lybia (before it surrendered) with their nuclear programs."
No question about that. But China already has the technology of nuclear arms. It is trafficking in its skill in nuclear arms. France is there to build more nuclear reactors in China (the Chinese already have some), because the Chinese government has concluded (correctly) that France can do it better, cheaper and faster than the Chinese themselves can.
French civilian reactors in China are as unrelated to China's nasty tendency to transfer nuclear weapons secrets as American computers in China are.
I understand - and I could be wrong - that to make this deal, France confirmed China's sovereign hold over Tawaiin. That bothers me.
