"The United States and China, North Korea's traditional ally, spent seven weeks negotiating the new sanctions, which include mandatory inspections of cargo leaving and entering North Korea by land, sea or air; a ban on all sales or transfers of small arms and light weapons to Pyongyang; and expulsion of diplomats from the North who engage in "illicit activities.""
"Russia's U.N. Ambassador Vitaly Churkin said that "by shutting down, as much as possible, the financing of DPRK's nuclear-ballistic programs, the idea is to ensure the return to the table of negotiations all the interested parties."
The resolution bans the export of coal, iron and iron ore being used to fund North Korea's nuclear or ballistic missile programs but not for general economic use. It prohibits all exports of gold, titanium ore, vanadium ore and rare earth minerals and bans aviation fuel exports to the country, including "kerosene-type rocket fuel.""
"U.S. Ambassador Samantha Power said it's estimated that the DPRK earns approximately $1 billion annually from coal — a third of its export income — and at least $200 million a year from iron ore exports."
