Hello everyone and welcome to Amanpur. Here's what's coming up.

A major blow to the world economy, US allies and adversaries react as Donald Trump launches a global trade war.

I speak with the German foreign minister Annalina Baerbach. Then Master Storyteller Chimamunday,

Ngozi Adichie, is back with her novel Dream Count,

a tour de force of women love and friendship.

And more fallout from the signal heard around the world.

Walter Isaacson talks to the accidentally invited journalist Jeffrey Goldberg. Welcome to the program, everyone. I'm Christiana Manpur in London. The world is now in a trade war. America fired the first shots. The White House imposed tariffs of at least 10% across every country, with steeper rates on those having a higher trade deficit with the US.

One economist says we haven't run this experiment in living memory.

China, which is hardest hit, calls their 54% tariffs unilateral bullying.

But US allies aren't exempt either.

The EU was slapped with 20%.

Here's the German Chancellor Olaf Schultz.

I believe the latest decision on tariffs by the U.S. President are fundamentally wrong.

This is an attack on a trade order that has created prosperity all over the world.

A trade order that is essentially the result of American endeavor.

The entire global economy will suffer from these ill-considered decisions.

Ill-considered decisions.

Analysts predict higher prices in the United States and warn of a global recession. The Dow plunged 1,500 points on opening markets around the world also fell sharply.

The response from the White House, we got this.

To anyone on Wall Street this morning, I would say trust in President Trump.

Let Donald Trump run the global economy.

He knows what he's doing.
