War with Iran casts shadow over Trump's visit to China

Beijing rolled out a lavish welcome for the first visit by a US president in nearly a decade, as Donald Trump arrived with top business leaders seeking major deals amid a fragile tariff truce. The trip is overshadowed by the Iran conflict, which threatens China's energy supplies due to the blockade of the Strait of Hormuz. China's ties with Iran and role in mediation add pressure, while tensions over Taiwan intensify, with Beijing warning it will firmly oppose any move toward independence.
