Tensions are rising across the globe.

President Trump’s trade actions have escalated from tariffs on imported washing machines and solar panels to a full-blown trade war with China, the world’s second-largest economy.

In Silicon Valley, antitrust clouds have darkened. Lawmakers and regulators in Washington, Brussels and beyond are investigating whether big tech has quashed competition to expand their dominance.

Those were among the topics that were explored on Thursday at The New York Times’s DealBook D.C. Summit in Washington. Andrew Ross Sorkin, DealBook’s founder, along with several of The Times’s leading journalists, moderated a series of workshops with business and policy leaders, providing fresh insights on how these tensions — and others — will shape the global economy.
