Beyond this month's talks between Chinese President Xi Jinping and US President Donald Trump, there’s an epic tale that has been unfolding for decades. It’s a battle to be the world’s number one power and a much bigger story than the latest meeting of these two men.  

Kishore Mahbubani is a former Singaporean diplomat who served as president of the United Nations Security Council. For two decades, he has argued that the West fundamentally misunderstands the rise of China and its challenge to American supremacy.

Mahbubani, who eventually turned to academia, now specializes in governance and public policy. In this conversation with Mishal Husain, he traces the story behind the Xi-Trump talks, the handshakes and the social media posts–and what may lie ahead.

Mahbubani also reveals how his own successes were made possible by Singapore’s remarkable growth.

The global bond market buckled over the past week. Yields on 30-year US Treasuries hit their highest level in almost 20 years, while long-term debt yields in the UK and Japan reached multi-decade highs. It’s a signaling effect, Bloomberg’s Enda Curran says, that investors around the world are increasingly convinced higher inflation is here to stay.

On today’s Big Take podcast, Curran and host David Gura discuss how supply shocks from the Iran war feed into longer-term inflation concerns, how AI might provide a way out for the global economy — and what this rout in the bond market means for the Federal Reserve, its new chair and the rest of us.
