According to International Law, as I understand it, China had no right to board and inspect that aircraft. It is considered to be sovereign US territory and can not legally be inspected without explicit US permission. As far as the crew goes, China may have the right to "debrief" them before returning them and their aircraft (uninspected, unless the US gave permission to the US, which it did not in this case).
I think that both China and the US are being too aggressive in this case. Admittedly, its hard to be calm when our people are being held against their will by a foreign nation, but we should still try. I think a week is too short a period of time to go through before starting WWIII.
China IS, supposedly, granting access to the crew today by US Diplomats.
