US planemaker Boeing Co. secured deals to provide aircrafts to Vietnamese airlines Bamboo Airways Co. Ltd. and VietJet Aviation JSC, as the companies seek for bigger operations in Asia and beyond.

The two carriers formally announced on Wednesday that they will be purchasing a total of 110 planes worth $15.7 billion from Boeing, with 10 orders of the wide-bodied 787-9 Dreamliner for Bamboo and 100 of the 737 Max for VietJet. The orders were valued at $2.9 billion and $12.7 billion respectively.

The deal came at the time of US President Donald Trump’s visit to Hanoi for a second summit with North Korean Supreme Leader Kim Jong-un.

The White House put the overall worth of the agreements at more than $21 billion, with a senior official saying the deals will support over 83,000 US jobs and provide increased safety and reliability for Vietnamese international travelers.

VietJet’s 100-aircraft commitment was provisionally revealed during the Farnborough air show in July 2018 and was confirmed later that year.

Boeing said the VietJet purchase, which was previously labeled as an undisclosed order on its books, took the airline’s MAX orders to 200 jets and included 80 of its latest 737 MAX 10 model.
