0606 GMT - Both China and the U.S. are likely to seek to "maintain relative stability" in their relations, although a broad bilateral agreement appears unlikely, according to Goldman Sachs in a research note. Treasury Secretary Scott Bessent and China's economic czar, He Lifeng, will likely discuss artificial intelligence, trade and rare earths before the official meeting between President Trump and Chinese leader Xi Jinping, GS says. "With the Iran war having escalated in recent weeks...the Iran war is likely to be discussed by Presidents Trump and Xi as well," the bank adds.
