Peru crackdown on illegal gold leads to new smuggling routes

Nearly all of Bolivia's exported gold was shipped to the United States, government data shows.
Peruvian President Ollanta Humala launched a clampdown late last year to tackle a decade-long boom in wildcat gold mining that has destroyed swathes of Peru's Amazon forest and laced its rivers with mercury.
But the proliferation of smugglers' routes into Bolivia shows how difficult it is to eradicate illegal mining without better coordination across frontiers.
