Jasem al-Manai, the managing director of the Arab Monetary Fund (AMF), said: "We agreed to allocate 10% of 2005's net profits of the funds to aid the Palestinian population."
The money will not go to the cash-strapped Hamas-led government, leaders of the funds said.
The AMF and four other Arab funds ended a two-day annual meeting in Rabat with the decision to participate in an Arab drive to bail out the Palestinians hit by a Western aid cut over Hamas's rejection of peace deals with Israel.
The Hamas-led Palestinian government inherited $1.3 billion in debt.
Israel has cut off $55 million in monthly tax transfers, while the United States and the European Union have cut aid to the government unless it recognises Israel and disbands its military wing.

"The aid money from the funds will not resolve the Palestinian sufferings, but it will help ease their hardships. The Palestinians are facing a crisis because of the financial siege."

But Fahad al-Ibrahim, the director general of the investment body, said his corporation was aiding Palestinians in its own way and will continue to do so.

"We asked the Palestinians to specify their needs and we are ready to help them with things like training staff or providing some office equipment," he said.
The funds were set up by Arab states to promote trade, investment and other economic cooperation within the Arab world in the hope of building a common market in the future.
Finance ministers and central bank governors from 20 Arab states attended the annual meeting of the funds, during which they discussed the region's economic outlook and cooperation.
