JIDDAH, SAUDI ARABIA, NOV. 13 -- Iraqi envoys fanned out to Arab capitals today to discuss Baghdad's conditions for attending an urgent summit on the Persian Gulf crisis, as proposed by King Hassan II of Morocco.

Amid a day of intense diplomatic activity in the Middle East, however, Iraq's principal Arab adversaries -- Egypt, Syria and Saudi Arabia -- maintained their official silence on Hassan's call on Sunday for a "last-chance" Arab conference to avert war.

Iraqi First Deputy Prime Minister Taha Yassin Ramadan, saying that Iraq "is with any serious Arab action at any level that would serve the Arab nation," arrived in Morocco with a message for Hassan from Iraqi President Saddam Hussein, news agencies reported.

Meanwhile, Second Deputy Prime Minister Saadoun Hammadi traveled to the North African countries of Libya, Tunisia and Algeria after conferring with Jordan's King Hussein in Amman on Sunday. A Jordanian official said the talks focused on the summit proposal.

Morocco's Foreign Ministry also said Soviet Deputy Foreign Minister Vladimir Petrovski was to arrive tonight in Rabat, Morocco's capital, to discuss the crisis, and then will visit Algeria, Tunisia and Libya, Reuter reported.

Saudi Arabia is waiting to see whether the Iraqi-Moroccan consultations will come up with a formula that could provide the basis for a successful summit, an Information Ministry official said.

Saudi King Fahd "likes to go for success. He doesn't like to go for failure," said Shehab Jamjoum, deputy director of foreign affairs at the ministry.

Egyptian President Hosni Mubarak, meanwhile, started a two-day trip to Libya. There was no explanation for the visit and no indication whether Mubarak, who has sent troops to the multinational force in Saudi Arabia, met with Iraq's Hammadi in Tripoli, the Libyan capital.

It is not yet clear whether the Saudis, who have about 350,000 foreign military troops stationed on their soil, were taken totally by surprise by Hassan's plea for a summit to avert war.

Saudi officials say they are skeptical that Iraq is willing to withdraw from Kuwait in line with U.N. and Arab League resolutions, and believe that Saddam is attempting to start up long, drawn-out negotiations that will link discussion of an Iraqi withdrawal from Kuwait to talks on the Israeli-Palestinian issue.

"The whole situation is that they feel it will not work," one Saudi said, adding that Saddam "is trying to gain the Arabs on his side and {a summit} might be a trap."

On the other hand, Fahd and Hassan have long been close and, while it apparently came out of the blue, the Moroccan monarch's plea for an Arab summit was preceded by intense consultations among Egypt, Syria and Saudi Arabia, first here and later in Damascus.

In addition, Hassan made his proposal shortly after Soviet President Mikhail Gorbachev, based on information from Yevgeny Primakov, his special envoy to Baghdad, suggested that Arabs themselves try again to solve the gulf crisis.

A Kuwaiti source who is not in the government said he believed a peaceful settlement was being seriously discussed and that the Saudis were being kept informed. He said it would be likely for any summit to be preceded by a smaller meeting of key Arab states directly involved in the conflict: Saudi Arabia, Iraq, Egypt, Syria and perhaps Jordan.

Iraq's conditions for attending a summit are that Baghdad be consulted in advance on the agenda, that the timing and location will permit Saddam to attend and that the gulf crisis be discussed in the context of regional "security" issues, including the Israeli-Palestinian conflict.

Ramadan said Iraq would reject a "gathering for endorsing conspiracies like the Cairo summit" last August when "the agent" Mubarak and "the traitor" Fahd "imposed their decisions." He added that Arab summits "should not be forums at which the American Pentagon's policies are translated into Arabic."

An official Moroccan source said reaction to Hassan's proposal for a summit within a week was "generally favorable" but few firm commitments to attend had been received. He said the government was having "communications problems" with the gulf states, Yemen and others.

The Iraqi News Agency said Saddam's letter to Hassan dealt with "the dangers confronting the Arab nation as a result of big conspiracy represented by the presence of American-Atlantic ground, naval and air forces" in Saudi Arabia.
