"We are hopeful coming out of the G20 summit that we are on a path to finding a trade agreement with China that's going to be productive," Muilenburg said in an interview with CNBC on Thursday.
China has become a key hunting ground for deals for foreign aviation firms thanks to surging travel demand, but the outlook has been complicated by Beijing's desire to grow its own champions in industry.
Muilenburg also said 737 MAX is a "safe aircraft", two months after a Boeing 737 MAX of Indonesia's Lion Air Group crashed, killing all 189 people aboard. He added that the planemaker had a healthy production backlog.
Boeing shares fell about 4 percent while the Dow and the S&P were down more than 1.5 percent.
