MOSCOW, April 12—Premier Kosygin met separately today with the Pakistan and Indian ambassadors as part of an apparently growing Soviet effort to seek a solution to the crisis caused by the civil strife in East Pakistan.

Diplomatic sources said that the Soviet Union was deeply concerned over continued bloodshed in East Pakistan and the resulting charges and countercharges between the Pakistan and. Indian Governments that have led Communist China to speak out on the side of Pakistan.

The details of Mr: Kosygin's meetings with Ambassador JamSheed K. A. Marker of Pakistan and Ambassador Durga Prasad ‘Dhara of India were not known. Tess, the official press agency, said both sessions were at the request of the ambassadors. It said the talk with Mr. Marker was hold in a “friendly atmosphere” and that Mr. Kosygin had “a friendly conversation” with Mr. Dhara.

The wide publicity given the meetings by the Soviet media indicated a Soviet desire to underscore Moscow's effort to remain impartial, even though the Kremlin had already publicly criticized the use of force to quell the East Pakistani independence movement.
