The Soviet Union dismissed President Carter's Middle East summit yesterday as "the Camp David trick" aimed more at increasing U.S. influence in the area than bringing about genuine peace.

The attacks against the summit in the government-run Soviet press seemed to sharpen the tone of Soviet criticism set Tuesday by Foreign Minister Andrei A. Gromkyo.

Gromkyo told a lucheon honoring visiting Greek Foreign Minister George Rallis that "separate experiments at the expense of the lawful interests of Arabs, whatever labels are attached to these experiments, do not constitute a record to peace in that area.

"Such a policy is unrealistic, myopic and in the long run prospectless,he added.

Tass, the official Soviet news agency, accused the United States yesterday of pursuing "selfish interests of a military character ensuring a strengthening of U.S. control over the Middle East and it oil arteries."

The agency added that Israeli Prime Minister Menachem Begin, who is meeting at Camp David with Carter and President Anwar Sadat of Egypt, would be using the summit to move closer to the North Atlantic Alliance.

The comments, emphasizing a belief that Sadat is taking a separate course in seeking peace with Israel, underlined Soviet irritation at his reliance on the United States to provide what Egypt hopes will be pressure on Begin for concession in the negiotations.

The government newpaper Izvestia said that, in any case, none of the participants expects much from the summit, scheduled to last of a week or more in the isolation of the hilltop retreat.

"The maximum success that would perhaps suit all would be an understanding on the continuation of the separate Egyptian-Israel talks," Izvestia said.

President Hafez Assad of Syria, meanwhile, predicted the summit could produce an agreement to end the state of war between Egypt and Israel. His comment, in a speech Tuesdat to Syrian troops on the Golan Heights, reflected fears in Damascus that Sadat is ready to sign a separate deal with Begin, even if it meant letting down his Arab allies.

In the southern Lebanese town of Sidon, Palestinian demonstrators burned an effigy of Sadat to protest the Camp David gathering. The demonstration, organized by the Democratic Front for the Liberation of Palestine, began at the Ein Hilweh refugee camp near the ancient port town.

Yasser Arafat, the over-all Palestine guerilla chief, said in a French television interview he hoped the summit would convince Sadat that Begin "will never give him anything."
