There are currently no production facilities in Vietnam for aircraft and spare parts. However, Boeing has managed to obtain 35% of the distribution market in Vietnam, and GE Aviation, in turn, supplies jet engines for the Boeing aircraft. For the future, conversely, Vietnam Airlines is planning to build a maintenance factory in conjunction with Rolls Royce and other companies. It has also signed a memorandum of understanding with EADS, a pan-European aerospace and defence corporation, that would let the corporation assemble and manufacture plane components in the future.
