Memorial events have been held across the Indian Ocean to mark 20 years since the tsunami that killed more than 220,000. Also on the programme, China has approved controversial plans to build what will be the world's largest hydropower dam on the Tibetan plateau; and the promise of non-alcoholic wine.
