UN chief Ban Ki-moon has arrived in the Democratic Republic of Congo accompanied by World Bank head Jim Yong Kim.
Mr Ban told the BBC that the introduction of a 3,000-strong intervention brigade to support the UN peacekeeping mission will help to protect the civilian population.
When asked if the new force would fight, he replied they were "mandated to enforce peace".
The UN has nearly 20,000 peacekeepers in eastern DR Congo.
