President Trump arrived in Beijing for a two-day summit with President Xi Jinping, with trade, rare-earth export controls, and the ongoing U.S.-Iran conflict all on the agenda, according to NBC News. Said Alexander Gray, a national security official in Trump's first term: "The important thing is establishing the ground rules, establishing the left and right bounds of the relationship, establishing what is acceptable to both parties and what would constitute an unacceptable break in the economic equilibrium." Trump brought more than a dozen CEOs to Beijing, including Apple's Tim Cook, Elon Musk, and Nvidia's Jensen Huang.
