Paris Hilton Mobbed By Fans in China -- Shanghai & Mighty

The U.S. may have problems with China -- but the Chinese are really into Paris -- Hilton -- who was totally MOBBED Wednesday in Shanghai.

Hilton was in town for the grand opening of the new Millions of Milkshakes location -- along with a bunch of other celebs who the locals obviously cared less about -- and the crowd went insane. Seriously, some people even brought signs.

Meanwhile back in L.A., the fans mobbing Paris were mostly creepy weirdos who secretly tried to smell her hair.
