The chief U.S. delegate to the UNESCO general conference here raised strong objection yesterday to principles set forth in some of the news media resolutions adopted after five weeks of politically charged debate.

Robin Chandler Duke objected specifically to language in one key resolution and in the UNESCO budget that states that the media have the responsibility for implementing social and economic policies.

Duke issued her statement as the conference went through the motions of giving final approval to the resolution already endorsed in the U.N. organization's commission dealing with culture and communications.

Meanwhile, Palestine Liberation Organization leader Yasser Arafat won a standing ovation for his fiery denunciation of the United States and Israel before delegates from 152 nations at the conference.

U.S. and Israeli delegates stayed away from the session, at which Arafat urged UNESCO to continue its support for a sovereign state in Palestine.

In another development, the Afghan government denounced a statement by its delegate to the UNESCO conference attacking the Soviet Union and sought unsuccessfully to have it struck from the record.

Akhar Mohammed Paktiawal accused Soviet forces in a speech here Saturday of dominating his country and killing and repressing its people. Meanwhile, a spokesman for the city of Frankfurt said Paktiawal would be given asylum in West Germany.
