Label a country to a currency manipulator need to go through a administration process. Those from corrupted Wall Street will do their best to block his way. Let's wait an see. The goal is not to label China a currency manipulator, the goal is to slash the trade deficit with China, thus economically squash Chinese communist regime.
And of course, he would say 'I have great respect to China' blah blah .. What you expect him to say in the meeting?
