My favourite it the "Designed in" tag. 
I have a few pairs of Meermin shoes. That’s “Meermin MALLORCA”. It’s even in their name. They’ve got a representative popping up on Styleforum doing PR for them and he was asked straight out where their stuff was made and if it qualified for made in Spain. Fella ‘fessed up they are made in Shanghai!!
Meermin aren't cheap for starters. And it's just right they shoud be ashamed of taking their manufacturing offshore, as Majorca has been a traditional Spanish footwear-making hub since a couple centuries ago, besides Alicante, Huelva and Albacete. In fact I know cheaper footwear brands that have nothing to envy to Meermin quality-wise and are manufacturing here.
Anyway, as Mike points out, not everything that comes from China is badly made, and I guess work conditions and wages, while far from Europe/USA's standards, vary from workplace to workplace. But as Chinese laws are surely "lax" (to put it mildly) regarding that, somewhat it's up to the foreing companies to improve them.
