The contract has a total value of 3.04 billion USD. The official signing ceremony took place at the Presidential Palace under the witness of President of the Socialist Republic of Vietnam Tran Dai Quang and President of the United States Barack Obama and the high-ranking delegations of the two countries.

This follows the signing of a memorandum of understanding between Vietjet and Pratt & Whitney of United Technologies Corp. at the Singapore Airshow in February 2016.
Pratt & Whitney, a subsidiary of United Technologies Corp., won an international tender to become the engine supplier for Vietjet. The engines supplied by Pratt & Whitney are rated with high operating efficiency indexes in Vietjet's operations. With this engine, Vietjet's fuel consumption has just been reduced by 17%, which is effective in business management as well as contributing to environmental protection.
