MOSCOW, July 30 (RIA Novosti) - A U.S. delegation headed by the coordinator for enforcement of UN sanctions against North Korea, Philip Goldberg, will arrive in Moscow on Monday to discuss measures against the reclusive state.

A source in Russia's Foreign Ministry said the agenda would cover the sanctions against Pyongyang that were agreed by the UN Security Council last month but no new sanctions would be discussed.

"The Americans are not pushing for additional sanctions not approved by the UN Security Council's Resolution 1874," the source said, adding that Russia was sticking firmly to its position that two-party sanctions are not productive.

Goldberg will meet on August 3-4 with representatives of Russia's Foreign Ministry and financial institutions on the effective enforcement of sanctions against Pyongyang. He will also visit several undisclosed Asian capitals in mid-August for similar consultations.

Additional sanctions under Resolution 1874 include the search of North Korean shipping vessels on the open sea if they are believed to be carrying prohibited materials, as well as freezing bank accounts if they are believed to be used to fund the country's nuclear or rocket programs.

North Korea said on Monday it was ready for bilateral talks with the United States but repeated it would not rejoin the six-party talks over its nuclear program, South Korea's Yonhap news agency reported.

Washington has been unresponsive to Pyongyang's request, demanding the North return to the international talks involving the two Koreas, Russia, China, Japan and the United States.

The communist state quit the talks and announced the restart of its nuclear program after the UN Security Council condemned its April 5 long-range missile launch. The Security Council imposed tougher sanctions on the North after it conducted its second nuclear test in May.
