President Joe Biden and his allies on Saturday announced plans to build a rail and shipping corridor linking India with the Middle East and Europe, an ambitious project aimed at fostering economic growth and political cooperation.

“This is a big deal,” said Biden. “This is a really big deal.”

The corridor, outlined at the annual Group of 20 summit of the world’s top economies, would help boost trade, deliver energy resources and improve digital connectivity. It would include India, Saudi Arabia, the United Arab Emirates, Jordan, Israel and the European Union, said Jake Sullivan, Biden’s national security adviser.
