UNITED NATIONS, N. Y. Dec. 1—A United Nations spokesman said today that Secretary General Thant wished “to have action by a major organ” of the United Nations before sending international observers to the borders of East Pakistan.

The statement was the first public explanation why the Secretary General had elected to take no direct action on Pakistan's request for observers, which was delivered here Monday.

Mr. Thant relayed the request to the President of the Security Council, whose members have been privately considering draft resolutions concerning the Indian‐Pakistani conflict.

However, Western diplomats say that the Council seems unlikely to act unless the situation deteriorates further.

Yesterday Prime MinisterIndira Gandhi of India opposed what she described as “persistent efforts to internationalize the issue.”

Last week Japan and also Belgium and Italy jointly were reported to have discussed privately possible Council action on the matter. But a spokesman for the Belgian delegation said today: “It is too early to comment on rumors concerning the substance of an eventual draft resolution.”

A spokesman for the United States delegation said today that Washington had assumed a “waiting position” on the subject.

The spokesmen for the United States and Mr. Thant made their statements in response to questions at the daily briefing in the Secretariat.
