The resolution, adopted unanimously, extends until July 31, 2007 the embargo on weapons headed to fighters in eastern part of the country.
The measure also asks UN Secretary General Kofi Annan to renew for the same period the mandate of a group of country experts charged with overseeing the embargo.
The resolution also asks the experts to include in an upcoming report, due on December 20, recommendations on measures to be taken to halt the illegal exploitation of the Congo's natural resources to fund the armed groups in the country.
These natural resources include diamonds, leather, cobalt, zinc, manganese, uranium, niobium and tantalum.
The council resolution also subjects political and military leaders who have enlisted child soldiers or who have committed human rights violations to individual sanctions such as travel bans and the seizure of assets.
