0938 GMT - Talks between President Trump and Chinese leader Xi Jinping Thursday won't deliver breakthrough on AI chips and rare earths, Jefferies analysts say. The Trump administration's plans for a Board of Trade to oversee a reduction in tariffs across a range of products is "the single most possible deliverable" from talks, the analysts say. On the U.S. side, Boeing aircraft and medical devices could benefit from talks, with the analysts taking encouragement from recent comments by U.S. Trade Representative Jamieson Greer. Agricultural and energy products could also benefit, they say. The two countries won't touch sectors of strategic importance, the analysts say. "We would not price in semiconductor or rare-earth relief."
