The company I work for has offices in Hong Kong, Shanghai and Beijing. We're making pots of money from world trade with China. It would be hypocritical of me to complain even if I considered Olympic protests to be in the right.
It's not as if this Tibetan business is recent. I remeber meeting refugees from there when I was in India back in 1990.
Olympic protests and boycotts are just an easy way to show disapproval. Trade tariffs and embargoes would show the Chinese that we're serious but it isn't going to happen.
