Trump is flying to China with Elon Musk, Nvidia's Jensen Huang, and Tim Cook in a last-minute, poorly planned trip that looks bad for US-China relations and possibly good for Trump family business deals.

• Trump brought family members including Eric Trump and his wife Lara, raising corruption concerns about using the trip to push Trump-branded golf courses and buildings abroad.
• The trip was planned so late that China did not know who was coming or what would be discussed until the last minute.
• Trump plans to ask Xi to "open up China" for US companies, even though 80,000 US companies already operate there and most of Apple's suppliers and half of Tesla's output are based in China.
• The US needs China to buy American soybeans and to help pressure Iran, but Trump's team keeps insulting China, including Lara Trump misspelling the country's name.
• Mixed messages on cars: Trump wants Chinese carmakers like BYD to build factories in the US to avoid tariffs, but Republicans keep attacking electric cars, including one lawmaker who sent a strange letter accusing a 10-year-old's teacher of indoctrination for an essay supporting EV tax rebates.

Outlook: Expect unpredictable announcements from the trip, possibly including soybean purchases, car factory deals, or new Trump family business ventures in China.
