BEIRUT, OCT. 17 -- Efforts are under way to arrange a meeting between Syrian President Hafez Assad and Palestine Liberation Organization chief Yasser Arafat at the Arab summit in Amman, Jordan, next month after an estrangement of four years, according to well-informed Palestinian sources.

A high-powered Palestinian delegation visited Damascus last week and met with Syrian Vice President Abdul Halim Khaddam to draw up a draft agenda for a "possible cordial meeting" between the PLO chairman and Assad at the Arab summit, set for Nov. 8.

The three-man delegation grouped Walid Khalidi, a Palestinian academic residing in Boston, Hassib Sabbagh, a prominent Palestinian contractor and financier, and Basel Akl, a London-based businessman.

Arafat's representatives and Syrian officials reportedly met in August in Cyprus, but the talks did not yield positive results.

The Syrians, prodded by the Soviet Union and eager to make inroads at the Arab summit, reportedly have changed their attitude and are now more willing to pave the way for a dialogue.

{A senior official of the Soviet Foreign Ministry met in Damascus on Saturday with Syrian Foreign Minister Farouk Charaa, The Associated Press reported. The official Syrian Arab News Agency said they discussed Middle East peace efforts and the Iran-Iraq war.}

A Palestinian source close to the team said its visit was preceded by two rounds of talks in Yugoslavia and Cyprus between Syria's Vice President Khaddam and Farouk Kaddoumi, the head of the PLO's political department.

Antipathy between Assad and Arafat climaxed when the PLO leader delivered a vitriolic speech in Damascus in May 1983 blaming Syria and other Arab states for the crushing blow dealt to the Palestinian guerrilla movement during the 1982 Israeli invasion of Lebanon. Arafat was promptly expelled from Syria and has been banned entry ever since.

Syrian troops and their proxies later fought bloody battles with Arafat loyalists in Lebanon, eventually forcing Arafat and his loyalists to leave Lebanon in December 1983.
