We should be doing everything possible to close our boarders to everything and anything that is Chinese.  They do not operate at all as a true partner when it comes to trade, they are bent on trying to control and overpower our interests and they cannot be trusted.  Building bonds and ties with other countries and cooling things down with China is exactly what we need to do.  Try telling that to our political leaders in Canada though.  Their too busy feeding at the trough to listen.
