State Department and Treasury Department officials testified to the House Foreign Affairs Committee about the US pressure campaign against North Korea's rapid progress toward a nuclear weapon that could strike America.
The hearing came a day after the UN Security Council imposed its latest sanctions over what North Korea says was a hydrogen bomb test Sept. 3, its most powerful atomic test yet.
The council banned North Korean textile exports, an important source of hard currency, and capped its imports of crude oil.
"Because of uneven, and sometimes nonexistent, international implementation, North Korea shrugs off the practical impact of many restrictions, and is still exporting prohibited goods such as weapons, minerals, and statues," Billingslea said.
