While Dobrynin, Sisco Discuss Mideast Political Settlement, Brezhnev Assails U.S.

The United States and the Soviet Union began Friday a detailed exploration of the possibilities of resuming United Nations mediation in the Mideast. U.S. officials emphasized that the crisis in Jordan had added to the urgency of such a search for a political settlement. Soviet Ambassador Anatoly Dobrynin conferred with Joseph Sisco, Assistant Secretary of State. The meeting was arranged last week after Mr. Dobrynin spoke with Secretary of State William P. Rogers. While there was no indication of progress at Friday’s Dobrynin-Sisco meeting, the two officials will meet again this week, according to State Department officials. At the same time it was reported from Moscow that Leonid Brezhnev, Russia’s Communist Party boss, accused the Nixon administration on Friday of talking about peace while carrying out “aggressive actions.” In a nationally televised Kremlin speech, Mr, Brezhnev appeared Irritated by Nixon administration efforts to get the Soviet Union to end military support for Vietnamese Communists and the Arabs and to work for negotiated settlements. He said “the defense capability of the attacked Arab states has been restored. Relations between the Soviet Union and the Arab world have expanded considerably and have grown stronger.”
