The Darien Gap is a 60 mile stretch of jungle that hundreds of thousands of migrants from all over South America trek through in order to reach the US-Mexico border. From there, they enter America in search of better lives.

These are usually migrants from Venezuela, or Colombia or Panama. But in recent years, a new group of people have appeared at the border, having paid people smugglers and hacked through the jungle. They often bring young children, clutch on to smartphones with which they check their routes, and watch social media videos that set out, step by step, the journey they are embarking on.

These are the Chinese, which in the last two years have been the fastest growing group of migrants being encountered at America’s southern border – over 37,000 last year, up from under 4,000 the year before. This year, there have already been over 21,000.

What brings them, and how unusual is this method of emigration when it comes to people from China?

On this podcast are Professor Meredith Oyen, an expert on US-China migration, and Amy Hawkins, senior China correspondent at the Guardian, who has come across a similar phenomenon on Europe’s borders.
