CAIRO, AUG. 22 -- Japan pledged economic aid for Egypt today to help its already debt-burdened economy recover from the effects of the Persian Gulf crisis.

The offer of assistance was announced by a spokesman for Japanese Foreign Minister Taro Nakayama after Egyptian President Hosni Mubarak met with Nakayama in Alexandria.

The president then told reporters that Egypt is likely to lose $2 billion a year in foreign exchange as a result of freezes on remittances from Egyptian contract workers in the gulf, reduced tolls on the Suez Canal and an expected decline in tourism.

Japanese spokesman Makoto Yamanaka gave no figures for the Japanese aid, saying that Nakayama and Egyptian Foreign Minister Esmat Abdel-Meguid would discuss details later.

Yamanaka said at a news conference that, while Japan's constitution bars sending troops overseas, Tokyo wants to contribute to the international effort to restore stability in the Middle East. "These measures will include economic assistance to those countries that are seriously affected by the present crisis," he said.

Japan is a major importer of oil from the gulf, depending on Kuwait and Iraq for 12 percent of those imports.

The Japanese foreign minister arrived here from Amman, where he told Jordan's King Hussein that Japan would provide economic aid if Jordan enforced U.N.-mandated sanctions on Iraq.

{In a letter to the U.N. Security Council, the Jordanian government said it will lose at least $2 billion a year if it implements the embargo, staff writer John Goshko reported from the United Nations. Jordan will lose remittances from workers in Iraq and Kuwait, government grants, oil sold at concessionary prices and long-term, soft loans. Jordan asked other countries to make up this loss with grants.}

Economists here said that, while Egypt's economy is likely to be severely shaken, it can expect the West to come to its aid in gratitude for Mubarak's marshalling of Arab support for the punitive sanctions against Iraq and of Arab military forces sent to help defend Saudi Arabia from a possible Iraqi attack.

Egypt, with a foreign debt of about $50 billion, including more than $12 billion owed to the United States, is facing a cluster of payment deadlines next month at a time when revenues may start falling as a result of the crisis.

With oil exports of about 300,000 barrels a day, Egypt can expect to gain some relief as oil prices rise because of the embargo on Iraq, the economists said. They said each dollar-a-barrel rise on the world market could gross Egypt $80 million to $100 million a year. That income would partly offset an expected downturn in other sectors of the economy.

An economist said remittances from contract workers in Iraq and Kuwait, which have exceeded $1 billion annually, are sure to be cut off.

Tourism, a $2 billion-a-year industry for Egypt, also may fall off, economists said, although Egyptian officials said that so far there has been no noticeable decline. They noted that normally any Middle East crisis, no matter how distant from Egypt, results in tour cancellations.

Economists said the approximately $1 billion that Egypt receives annually from Suez Canal fees probably also will be affected by the crisis.

Because of the Western-enforced oil embargo on Iraq, fewer tankers will pass through the canal. However, the economists said, some shippers who normally sail around the southern tip of Africa may anticipate lower canal fees and use the Suez instead.

"Taking the positive and the negative effects into account, there is still going to be a very large impact on foreign exchange, which will affect the value of Egyptian currency," one economist said. "On balance, the impact is definitely going to be adverse, and we are watching the situation closely."

About half of Egypt's debt to the United States is in high-interest military loans. For each of the last five years, Egypt has kept up debt payments. Egypt's current-account deficit, the difference between expenditures and revenues for goods and services traded, stands at about $1.4 billion. Its trade deficit is $7.5 billion.

With debt arrears mounting, Egypt has been negotiating for more than two years with the International Monetary Fund for an agreement on what kinds of economic reforms the IMF may require before assisting Egypt in debt rescheduling.

Prospects for an accord appeared to diminish earlier this year when the IMF said the government had not done enough to cut its nearly $6 billion budget deficit. Analysts now say the gulf crisis could significantly affect those negotiations.

"The invasion and Egypt's response introduce a new element. It throws all the assumptions that have been the basis of the negotiations out of kilter," a Western economist said.

Citing a series of military aid payments to Washington that are due on Sept. 1, an economist said, "Whether they can make {those payments} remains to be seen. It depends on how fast their oil revenues come in with the higher prices. They have made it clear that they are pressing for debt relief, and this is under active consideration."
