UNITED NATIONS — Having helped rout one powerful rebel group in the eastern part of the Democratic Republic of Congo, United Nations peacekeepers are expected to turn their attention to subduing another, diplomats said Wednesday, as the Security Council prepared to draft a statement on the next steps in that vast, mineral-rich country.

The move could be instrumental in bringing some stability to a region reeling from what has seemed like endless war.

The United Nations has sent its largest peacekeeping mission to the country, including a 3,000-strong intervention brigade with a new, more aggressive approach to peacekeeping. Rather than protecting civilians in imminent peril, it is charged with going on the offensive and “neutralizing armed groups” before they cause more harm.

United Nations troops have already aided the Congolese Army in fighting the M23, a feared rebel group, which United Nations experts have said is supported by Rwanda.
