Seen the news recently where some US and Canadians were concerned about buying services from China regarding security and protection of sensetive information or secrets. now in todays news the China ambassador to canada is reported to have said:" Prove China spy allegations or 'shut up'. this is in todays news in Canada reporting on coments from ambassador Zhang Junai. looks lke some trade issues are croping between Canada,US, China. Canada looks like its going to block sale of oil company nxy to China as well. we live in interesting times. China might argue protectionism, but what can they do about it. This should signal the governments preferance for made in USA equipment and software for sensetive areas, and private industry might just follow that lead.
