The United States Congress will push to tighten the screw on North Korea with legislation making the communist nation's access to the global financial system more difficult, diplomatic and congressional sources said Sunday.
Rep. Ed Royce (R-CA), the chairman of the U.S. House Committee on Foreign Relations, is working on a bill aimed at tackling Pyongyang's ability to gain hard currency, according to the sources.
The move is part of a series of reactions by the U.S. Congress to North Korea's nuclear test last week, while the Obama administration is focusing on first hammering out a unified response by the U.N. Security Council.
