Italian Prime Minister Giulio Andreotti today told French President Valery Giscard D'Estaing that he does not believe that President Carter's human-rights campaign is jeopardizing East-West detente.

Giscard, who met West German Chancellor Helmut Schmidt tonight to discuss the German leader's talks with the American President, has said that Europeans increasingly oppose Carter's initiative.

He was quoted in Newsweek magazine as saying in an interview that the human-rights campaign threatens detente.

But Andreotti disagreed. After lunch with Giscard, he told reporters:

"I think that the U.S. President is committed to upholding the existing balance. When he speaks of human rights and civil rights, he is formulating a concept that is common to us all."

Andreotti will visit Washington for talks with Carter later this month.

Giscard and Schmidt met in a restaurant near Strasbourg for talks believed to be focusing on Schmidt's meeting with Carter last week.

While in the United States Schmidt acknowledged that there are differences in perspective on human rights between the United States and West Germans have feared that Carter's program would endanger the exodus of ethnic Germans from Eastern Europe.

Giscard and Schmidt were also expected to compare notes on their recent meetings with Soviet leaders and the lack of progress in the U.S. Soviet strategic arms limitation talks.

Giscard and Andreotti also discussed enlargement of the European Common Market to include Greece, Spain and Portugal, a move Andreotti said he favors.

Andreotti, also conferred with French Prime Minister Raymond Barre on Common Market problems.

The two prime ministers reportedly agreed on the need for a review of the common market's agricultural policy on Mediterranean products in view of the possible entry of the three Medterranean states into the nine-member group.

They insisted that new members should not jeopardize the interests of French and Italian farmers, particularly in fruits, vegetables and wines.
