Behind the scenes at China's Harbin snow festival
This week, we take you on a trip into a real-life winter wonderland. The Harbin International Snow and Ice Festival, famed for its gigantic illuminated sculptures, has officially kicked off in northern China. The biggest ice festival in the world is expected to attract one million visitors this year. Julia Sieger gives us a sneak peek.
But we begin in India, where a financial and technological revolution is under way. The country is being demonetised at a furious pace, with Indians from all social backgrounds urged to open bank accounts and go fully digital. It's part of PM Narendra Modi's war on the shadow black economy. Yet critics say the pace of change is leaving many Indians behind.
We also head to Indonesia, where thousands of illegal miners risk serious injury and death at the bottom of an opaque global supply chain. Every day, they dredge the seabed for tin, a vital component of smartphones and tablets.
And we finish in Pakistan, which is slowly emerging from a long-term power crisis. But the after-effects of this sustained blackout are still being felt in the textile sector. Once the engine of the Pakistani economy, the textile industry is struggling to get back on its feet, faced with high energy costs and a decade lost to competitors.
