Or it could be just a veiled snub against Hillary. It's ironic that the US media doesn't report nearly at all on anyone elses politics except their own. Now just because Xi doesn't show up, it must be turmoil behind the scenes or he's gravely ill. I would snub Hillary for her irresponsible show-boating only and no substance as Secretary of State. She's about to leave office anyway. Why bother with her? Lately I've been reading a lot of stories suggesting Hillary has been setting her own agenda apart from Obama. And since Hillary has higher approval ratings than Obama himself, he's just letting her do what she wants especially since it's been more PR trips and not actually diplomacy. She's a lame duck Secretary of State. If you think about it she is setting up to run for President in 2016. Before she was attacked for her lack of foreign policy credentials. Remember her claim that she was under fire in Kosovo. It was 80s comedian Sinbad who was on the same plane who called her out on her fib. Her run as Secretary of State has been more about image which is good to say something about foreign policy when running for President. Look at Sarah Palin who never went to foreign country before. Then she goes to Hong Kong and gives a speech just so it can be said she has a foreign policy for an upcoming possible run as President. Is that all it takes?
