India rejects China's attempt to rename disputed places

In this week's show we see how Indian officials are furious after China renamed 11 places in Arunachal Pradesh. It is a disputed Himalayan border region under Indian control, which Beijing considers part of southern Tibet. Next, we head to Nepal, which is home to the "most dangerous runway in the world". We get a bird's-eye view of a tiny airfield in the mountains, where tricky landings are a risky but vital part of everyday life. Finally, we head to Thailand, where a cannabis pipe dream is going up in smoke. A year after decriminalisation, marijuana remains a politically divisive issue in the country ahead of elections.
