The sky is hidden by smog in Lanzhou on the Yellow River; this transport and manufacturing hub is pumping Chinese goods out to the world. In this last programme, we find out how the Belt and Road Initiative has brought new people into this growing metropolis and how businesses are benefiting from the new infrastructure.

Cambodia: New riches on the coast
When it comes to South-East Asia, China’s presence is most felt in Sihanoukville. Cambodia’s once sleepy backpacker resort has been transformed by Chinese investment – the sheer speed of development has divided local opinion. Chatting to everyone from bus drivers to market stall holders about their experiences of a changing town, we ask, how has the Chinese influx affected the people of Sihanoukville?

Kazakhstan: A port in the sand
Khorgas in Kazakhstan is going through an economic boom and Chinese trains stop here and their loads are shifted on to the Kazakh trains. This region was the gateway of the ancient Silk Road, a meeting place of cultures and languages. We meet nomads who have called this land home for centuries and pioneers developing a city for the future.

Raha: The joy of the train
The new Chinese Mombasa–Nairobi railway has finally overturned over 100 years of history by replacing the British-built Uganda Railway - the most strategically important conduit in the scramble for Africa. Cutting the time between Mombasa and Nairobi from 10 hours to 4.5 hours. Chinese interests may be at the centre of these investments - but the impact is regional, how is the Kenyan population benefiting from this new service?

How modern living is changing our faces
Dr Vybarr Cregan-Reid looks at how modern living is changing our faces. With the help of professor Saw Seang Mei in Singapore and the UK's top ophthalmologist, professor Chris Hammond, he tells the story of how baffled scientists sought to understand the rocketing rates of myopia in the Far East, where more than 80% of teenagers are short-sighted. Dr Cregan-Reid learns about the various theories put forward before Australian researchers cracked the mystery in 2004. Spoiler alert: It is not to do with screens.
Evolutionary biologist Professor Noreen von Cramon-Taubadel, from New York State University, tells Dr Cregan-Reid about how our jaws have been reacting to changes in our diet. They are getting shorter and less dense, but our teeth are erupting as if it is still 50,000 years BC. At London's Natural History Museum, Professor Fred Spoor takes us through the impact the modern world is having on our teeth and the shape of our mouths.
Back in Singapore, the country's leading plastic surgeon, who spends most of his day reshaping people's jaws, tells Dr Cregan-Reid he thinks our faces are getting shorter but wider because of what we eat and the impact of stress on facial muscles.
In the third and final part of Changing World, Changing Bodies, we learn why the 'you' that you see in the mirror most days may not be the 'you' that your DNA had planned.
