In the wake of a rising tempo of criticism in the UniteStates against Israel's stance on the occupied West Bank and Gaza Strip, Foreign Minister Moshe Dayan has reassured his senior staff that the government is sticking to its decision to keep the territories' status vague for the next five years.

"We do not view the partition of Judea and Samaria as a way to a solution . . . The only way we can see is a modus vivendi in a manner suggested by our plan. After five years we will be able to determine the nature of the future relations," Dayan said.

His remarks, made in a closed meeting at the Foreign Ministry Thursday, were released yesterday.

The plan he referred to would grant Palestinian Arabs in West Bank and Gaza limited self-rule in place of the current military government, but would retain an army presence in the territories for security purposes.

In its response to the Carter administration's questions about what will happen after the five-year experiment in autonomy, the Israeli government responded simply that "the nature of the future relations" will be considered after five years.

In firm language, Dayan complained that the Arabs have ruled out every Israeli suggestion "at the same time that the American administration ignores Egypt's uncompromising position." Egytpt, Dayan said, is still insisting that Israel withdraw first and discuss security arrangements later.

"We insist that no one delude himself into thinking that in such an argument Israel would obtain suitable security arrangements. Such a demand restores the situation which prevailed in the region and because of which three wars broke out," Dayan said.

Referring to U.S. questions and apparently also to the State Department's suggestion that they were answered by Israel less than completely, Dayan said, "We would like to see a continuation of negotiations, and not additional questionnaires."

Dayan reiterated that at the end of five years, a number of possibilities for a permanent status of the areas might present themselves, such as continuation of the limited self-rule, a "tightening of the tie with Israel or with Jordan, or a combination of the three."

The Foreign Ministry refused to respond directly to the assertion Thursday by Sen. Jacob Javits (R-N.Y.) that Israel's answers to the American questions were "the wrong signal at the wrong time" and that they invited the Carter administration to impose a peace plan of its own.

A ministry spokesman said Dayan would have "no reaction to his (Javits') words," but the spokesman added that Dayan, in his remarks to his senior staff, characterized the American reaction as "understandable."

The thrust of Dayan's attitude, the spokesman said, was that the Carter administration "not only asked questions but suggested answers," and that when Israel's reply did not match the specifications, there was bound to be disappointment in Washington.

President Anwar Sadat of Egypt made overtures yesterday to the Arab states he alienated by his go-it-alone diplomacy. Libya has been one of his most vocal critics.

"We are ready to restore diplomatic relations with Libya," Sadat told a news conference after meeting with presidents Ahmed Sekou Toure of Guinea and Mohammed Siad Barre of Somalia. "But first slander campaigns against Egypt should be stopped because all those rejectionist countries owe much to Egypt."

Tosre said later that Sadat told him Egypt was prepared to restore relations with all five rejectionist nations - Libya, Iraq, Algeria, Syria and South Yemen. He broke ties with the five after they held a summit and vowed to "freeze" relations with Egypt.

West German Chancellor Helmut Schmidt criticized Israel for not having made an adequate response to Sadat's peace initiative.

Schmidt, speaking at a joint news conference in Bonn with visiting Saudi Arabian Crown Prince Fahd, said he would discuss Israel's future Middle East policy with President Carter next month. Carter is scheduled to visit West Germany.

"You know that West Germany has very much admired President Sadat's courageous step. Israel's answer has so far been inadequate," Schmidt said.

In Tel Aviv, Israeli military sources said that Israel and Egypt continue to maintain high level direct contacts and that an Israel military delegation remains based near Alexandria despite the freeze in peace negotiations.

In Beirut, the Lebanese government said it is deploying army troops for the first time since Lebanon's civil war in an effort to halt "increasingly grave" unrest between rival Christian militias.

Northern Lebanon has been the scene of fighting between rival Christian groups and in the south U.N. troops are battling both Palestinian guerrillas and Christian militiamen allied with Israel.

U.N. forces move into more southern Lebanese villages in their effort to reestablish security in the region following the withdrawal of Israeli occupation troops 10 days ago.

An Irish unit entered the village of Aireh and immediately began dismantling cluster bombs left behind by the Israelis. Three mines were defused.

A U.N. statement said the U.N. force has moved into 14 "potentially key position" in the past ten days.
