Currency wars, Chile's miners and Amsterdam's cafés

After the crisis, the war – currency wars, to be precise. What can regulators do to stop countries from using devaluations to boost their economic growth? We also have the latest on the plight of the Chilean miners – will they be freed soon? And we also look at Amsterdam, where the spliff-friendly café beloved of many a curious tourist may soon be more strictly regulated. Has pot-tourism had its day? David Gardner presents, with Alan Beattie in Washington, Jude Webber in Buenos Aires, and Michael Steen in the studio. Produced by Rob Minto
