Securing aid to the cash-strapped Palestinian National Authority (PNA) is on the top of Abbas' agenda, Abbas' senior aide Saeb Erekat, who is accompanying Abbas in the tour, told local radio the "Voice of Palestine" via phone.

"Abbas will deliver a message to urge donors to continue aid and not to impose collective sanctions on the Palestinians for electing Hamas into power," Erekat said.

"Abbas will also call upon the international community to give a chance to the weeks-old new Palestinian government led by Hamas," he added.

Defeating Abbas' long dominant Fatah movement in the January legislative polls, Hamas, or the Islamic Resistance Movement, has taken control of the Palestinian parliament and then the government.

In response to Hamas' persistence in refusing to recognize Israel's right to exist, renounce violence and honor previous Palestinian-Israeli agreements, the United States and the European Union have suspended direct aid to the Hamas government.

Israel, meanwhile, has also halted the monthly transfer of about 50 million U.S. dollars of tax revenues it collects on behalf of the Palestinians.

The Quartet of key Mideast peace brokers -- the United States,Russia, the European Union and the United Nations -- agreed last Tuesday to create a new mechanism for funnelling funds to the Palestinians and run it over a three-month trial period in a bid to fend off a humanitarian disaster in the Palestinian territories.

But the mechanism will bypass the Hamas government.

Erekat also urges the Quartet to up pressure on Israel to "stop daily aggressions against the Palestinians and bring the peace process back to track."

Abbas is scheduled to meet Russian President Vladimir Putin in Sochi, Russia, later in the day.
