Lufthansa Technik would also supply materials for its Boeing 787 and Airbus A320 aircraft, the airline said in a statement.
It also signed MoUs with two other European firms, AVIAREPS and Airbridge International Agencies for market expansion and cargo transport consultancy.
One more, with Air France Industries KLM Engineering & Maintenance for engine maintenance, will be signed Thursday.
The airline launched its first commercial flight between Hanoi and Frankfurt late last month, and plans to operate on the Hanoi-London route from March 22, it said.
