In essence what is going on, is that the brief pick up in German and US GDPs on the trade balance side, are being facilitated exclusively by the credit bubble in China. By dint of China being able to recognize GDP at production instead of expenditures (like normal Western countries), China is now trying to back fill into the trade void left from the collapse of Western economies by promoting the same kind of irresponsible lending (and borrowing) that lead the US economy to its current sorry state. This will eventually end very, very badly.
