In 2018, Rimu joined Young Women Leaders for Peace within the Global Network of Women Peacebuilders (GNWP), established in collaboration with the local non-governmental organisation Jago Nari Unnayon Sangsta (JNUS) and supported by
UN Women. As part of this role, she first visited
Rohingya refugee camps in Cox's Bazar whilst taking part in JNUS' literacy and numeracy initiative. She subsequently helped devise formal literary and numeracy training courses to deliver to
Rohingya children living in the
Balukhali camp following finds that 50% of Rohingya children under the age of 12 were receiving no formal education. Rimu has also used radio broadcasts and plays to spread awareness of these issues. Rimu has cited Bangladeshi prime minister
Sheikh Hasina as amongst her inspirations. == Recognition ==
