China’s eco-cities: Sustainable urban living in Tianjin

It takes less than an hour on the new high-speed train line to travel the 150 kilometres (93 miles) southeast from Beijing to Tanggu, the dirty coastal port town of nearby Tianjin – the world’s fifth biggest port. Here, you can see signs of the past and present: fine colonial architecture built by European settlers a century ago nestle among the gleaming modern high-rises. But for a glimpse of the future, I am driving a few minutes up the coast from Tanggu to see a city so new that most of it is still being built.
