What Trump and Xi are demanding behind closed doors

China has resisted the Trump administration’s urgings, and economic threats, to use its leverage to prod Iran to agree to U.S. terms to end the nearly 7-month war. Xi Jinping wants to see Trump permanently halt arms sales to Taiwan and loosen export restrictions on cutting-edge advanced chips. The two sides Wednesday agreed to extend by two months a one-year trade truce set to expire Nov. 10 as they work to find a more durable agreement.
