What Do You Think About Trump's Phone Call With President of Taiwan?

The delicate balancing act over Taiwan has been a cornerstone of US-China relations for decades, but it appears that Donald Trump wants to shake it up.

It was the first publicly-reported contact between a Taiwanese leader and a US President or president-elect in forty years, and China responded immediately, saying it had "serious concerns". On this week's Newshour Extra, Owen Bennett Jones and his international panel of experts consider the future of the US-China relationship, and what any changes could mean for the rest of the region and the world.
