The US-led Effort to Lobby for New Sanctions on North Korea

U.S.-led effort results in three rounds of new UN sanctions, the most stringent that North Korea has ever seen. The sanctions are aimed at punishing North Korea for their defiance and stopping the flow of money into the nuclear program. There's a total ban on some of North Korea's biggest exports,. They severely restrict the flow of fuel into the country. Even China, North Korea's main benefactor and ally, signs onto the sanctions.
