Boeing is close to sealing a deal that would sell 500 of its MAX 737 Boeing aircraft to China. Securing a 500-plane order from China would end a multi-year drought for Boeing in one of the world's largest aviation markets, providing a massive boost to its backlog and future cash flows. WATCH. This is a highly lucrative catalyst for Boeing, but it is entirely dependent on the political success of the upcoming US-China presidential summit. The deal is highly politicized and could be easily scuttled if diplomatic talks reach an impasse over tariffs, tech restrictions, or Taiwan.
