The United States and North Korea began discussions Tuesday on Washington's financial restrictions against the Pyongyang regime for its alleged counterfeiting and other illegal activity, a US Embassy official said. The meeting, held amid six-nation talks on the North's nuclear program, was to address an issue that lead the North to boycott the talks for 13 months. The embassy official confirmed the meeting had started but gave no details on where they were being held. Daniel Glaser, the US Treasury Department's deputy assistant secretary for terrorist financing and financial crimes, was in Beijing for the meeting. The North Korean delegation that arrived here Tuesday is led by O Kwang Chol, president of the North's Foreign Trade Bank of Korea.
