In this holiday special, The World takes you to China. We visit Shenzhen, which has become the most thriving megacity in the world — without the air pollution, overcrowding and failing infrastructure that often accompany rapid expansion. Also, an unpacking of the latest diplomatic spat between China and Japan over Taiwan. And, a peek at the future of transportation innovation from the Automotive World China Exhibition, complete with electric cars and self-driving sanitation vehicles. Plus, the story of a mother who traveled with her adopted daughter to China in search of answers about her past.

It’s been an adventurous three decades for The World and we’re glad to have you with us as we celebrate our 30th anniversary. In this special New Year’s show, we highlight some of our reporting over the years. We bring you a discussion with Neil Curry, who helped create the show and was The World's first executive producer, as well as a conversation with our reporters Matthew Bell and Shirin Jafaari, who discuss how their coverage of major global news evolved after 9/11. Also, we look at our coverage of the environment in a time of climate change. And, we take a listen to some of our favorite music over the years. Plus, you’ll even have a chance to test your global knowledge as our hosts play a round of Geo Quiz trivia.

As we wrap up the year, The World takes a look back at some of our favorite stories from 2025. We visit coffee raves in Barcelona. Also, a landmark performance for a female conductor at the Tehran Symphony Orchestra. And inmates in Milan who are repurposing the wood from migrant boats into musical instruments. Plus, crate digging for vinyl records with a collector in Dubai.
