In July 2018, at the NATO Summit in Brussels (Belgium), the President of Romania, his Excellency Mr. Klaus-Werner IOHANNIS, announced Romania’s offer to develop a command and control capability on its territory in order to adapt to an increasingly unstable regional and international security environment and in the context of the adaptation process of the NATO Command Structure. Romania’s commitment has been welcomed by the Allies. Further discussions and meetings within the Alliance paved the ways for preparing the establishment and development of the new HQ.
On April 16, 2020, the Homeland Defense Supreme Council approved the establishment of the Headquarters Multinational Corps South-East on the national territory, in Sibiu, with temporary deployment in Bucharest. Romania officially committed to the role of framework nation.

The framework has already been implemented for the Headquarters Multinational Division South-East (HQ MND-SE) and the NATO Integration Force Unit (NFIU).
In March 2020, the Post Allocation Conference and the Memorandum of Understanding Conference took place at the Supreme Headquarters Allied Powers Europe (SHAPE) in Mons, Belgium, with the participation of representatives from many NATO member states.
