One Boeing 737 MAX flying from Seattle has arrived at the Guangzhou Baiyun International Airport in South China's Guangdong Province on Saturday, flight information provider VariFlight revealed on Saturday.

The delivery ends a nearly five-year freeze since China suspended most orders and deliveries of Boeing planes in 2019 following two fatal crashes of the 737 MAX in other countries.

Information shared with the Global Times shows that the plane, operating under the flight number of CZ5073, has joined the China Southern Airlines fleet.

The delivery of the Boeing 737 MAX comes at a moment as the U.S. plane manufacturer is in its turmoil.

Reuters reported that the U.S. Federal Aviation Administration on Wednesday tightened pressure on Boeing by barring the troubled planemaker from expanding production of its best-selling 737 MAX narrowbody planes, following "unacceptable" quality issues.

Boeing CEO Dave Calhoun faced questions from senators on the Alaska Airlines incident in a series of meetings on Wednesday on Capitol Hill. Senate Commerce Committee chair Maria Cantwell said she would hold hearings to investigate the root cause of Boeing's safety lapses, according to Reuters.

Regarding the delivery of MAX series in China, China's Foreign Ministry said on Thursday that the Boeing 737 MAX8 model has met delivery requirements set by Chinese regulators as of December 8 of 2023.

Before the delivery of MAX, a 787-9 Dreamliner ordered by Juneyao Airlines had been delivered in December of last year, and it is also the first time since November 2019 that Boeing has delivered a 787 Dreamliner plane to a Chinese airline.

China is regarded one of the most rapidly developing aviation markets in the world, as Boeing forecast in September of last year that China will need 8,560 new commercial airplanes through 2042, driven by economic growth well above the global average and increasing public demand for air travel.

Chinese home-developed C919 aircraft also gear up the flying in China. China Eastern Airlines said on Saturday that all the C919 aircraft it received are being put into the Chinese New Year's travel rush.
