They said that in addition to the sacrifices of Rwandan soldiers, the actual cost could be 10 times bigger the support package. Impact of Rwandan operations By December 2023, an estimated 90 per cent of terrorist-hit areas had been secured, according to Mozambican military leaders. As The New Times reported, trading centres, ports and airports had reopened in the affected areas. An estimated 250,000 people had returned to their homes. European energy companies have also resumed their operations in the once-unstable region. In January this year, French company TotalEnergies have announced the resumption of its $20 billion liquefied natural gas (LNG) project that had stalled for about five years. Rwandan troops have participated in social and medical activities. They conduct Umuganda community service with locals and they also provide free medical outreach programmes. As part of their civil-military activities, they have also built markets and classrooms for local schools, in addition to the donation of school materials.

Government officials said that despite cost of the operations being at least 10 times more than the EU support, the troops will be withdrawn if their contribution is not appreciated. On March 13, a new contingent departed to Cabo Delgado to relieve their colleagues who have completed their tour of duty in the Southern African country.
