LAKE SUCCESS New York, Nov. 12--The United States welcomed tonight the renewed Russian offer to start now on solving the world's arms problems and Soviet Russia showed a great desire to take up the subject as quickly as possible.

U. S. Senator Tom Connally, (D.Texas) chairman of the Senate foreign relations committee and an American delegate to the U. N., said that the United States welcomed Russia's "cooperation" in the matter of disarmament.

Almost simultaneously, Audrei A. Gremyko, Soviet delegate informed the important political committee of the United Nations that it was wasting too much time talking about the relations between the Security Council and the Assembly "at the expense of the more important questions of disarmament, economic issues, and the presence of troops on non-enemy territory."

"We should spend more time on more productive work," Gromyko said.

Assembly delegations were considerably interested in the speech made last night by Russian Foreign Minister V. M. Molotov to the Foreign Press Association in New York in which he said that the proposals of Russia and the United States on arms, reduction "can be harmonized."

The latest developments in the arms picture indicate that both Russia and the United States are favorable to early discussion but there is no indication when the matter will come up. It stands No. 7 on the agenda of the political committee, behind three vote item and Russia's pointed questions on the dispositions of allied troops in alien non-enemy countries. All of these are bound to bring about prolonged debate.

Mention of a "third world war" flared up in the social, humanitarian and cultural affairs committee when Leo Mattes, of Yugoslavia, protested bitterly against a committee vote. Mattes had asked that the proposed international refugee organization in resetting refugees consider the wishes of neighboring countries as well as the country of reception.

"Camps which are the center of enemy activity run by military authorities exist on the very Yugoslav border. They are engaged in acts of terrorism on the very soil of Yugoslavia. They hope to invade our country which has suffered so much through the war. To ignore this is to bid for a new world war. Mere numbers around a council table like this cannot decide whether or not the birthplace of the third world war already exists. I serve notice that the Yugoslav government may protest
