So you are saying that bowing is wrong, even though it is a time honored tradition?
Do you need plastic sheets for your beds still?
I have traveled to 28 foreign countries and met several VIP's in the far and middle east. My company briefing covered acceptable protocol when meeting foreign dignitaries. The accepted method of bowing was to keep your shoulders level, smile, and merely nod your head down while keeping eye contact. The Chinese instructor told me that a full bow indicated subservience and you lost the respect of the dignitary at that point.
Although it is about 6 years too late, Obama either needs some similar instructions or needs to pay attention if anyone in the White House knows the proper protocol.
