Special Ambassador Robert S. Strauss will lead a four-day mission to Cairo and Jerusaleum beginning next Monday to open up discussions of expanded U.S. trade with the two Middle East countries.

"Our first hope is to show that we can put some economic stability, not just arms, into that area," Strauss said. The plan for the trip came out of Carter's discussions with Israeli Prime Minister Menachem Begin and Egyptian President Anwar Sadat when the peace treaty was signed here last month.

Strauss said that his group will "take a look" at agriculture, housing and textiles, among other areas. Included in the mission are key figures from U.S. textile industry and labor, Jerome Gore, chief executive officer of Hart, Schafferner & Marx, and Murray Finely, president of the Amalgamated Clothing and Textile Workers Union.

A Strauss aide said an effort would be made to help the Egyptian textile industry set up some new product lines.

A congressional delegation will include Sen. Abraham Ribicoff (D-Conn.), Rep. Ken Holland (D.S. Car.) and Republicans who have been invited but have not yet accepted. The government representatives will include officials of the State, Commerce, and Treasury departments, Export-Import Bank, and the Overseas Private Investment Corp.

Officials stressed the bilateral nature of the talks. Strauss will not get involved in joint Egyptian-Israeli expects to develop cooperative economic projects between the two former warring states.
