The summit comes as Washington tries to stabilize ties with its largest strategic rival. Trump said before departing for his trip that Washington did not need Beijing’s help over Iran, but China remains a key diplomatic player because of its ties with Tehran and its energy trade. The US president is traveling with senior officials and business leaders, including Nvidia CEO Jensen Huang and Elon Musk, underscoring the technology and market-access agenda behind the visit. The talks are expected to cover Taiwan, tariffs, trade and advanced microchips. Beijing opposes US arms sales to Taiwan and has become more assertive since Trump’s 2017 visit to China.
