Salah al-Bardaweil, spokesman of Hamas in the Palestinian Legislative Council (PLC), said that the U.S. stance would not offer any stability in the region because it sided with the Israeli occupation.

"We consider this position a kind of injustice and would rob competence of the U.S. to be a neutral part in the Middle Eastpeace process," he said.

Chief Palestinian negotiator Saeb Erekat, meanwhile, feared that the West would impose the same isolation on Hamas-led government as one on the Palestinian National Authority (PNA) led by the late Palestinian leader Yasser Arafat in 2002.

"Unfortunately this would return to the stage when the United States and the European Union decided not to contact Yasser Arafat and isolate him," Erekat told radio "Voice of Palestine"

He added that the US and the EU contacted only the Palestinian cabinet before Arafat died in late 2004.

The United States, Canada and France ordered a ban on contact with Hamas government shortly after it took oath of office on Wednesday.

Commenting on the Western countries' decision to continue humanitarian aid to the Palestinian people while suspending aid to the PNA, Erekat urged not to impose collective punishment on the Palestinian people for giving the radical Hamas an election victory in January.

"What is important is continuing the donor countries aid to the Palestinian people," Erekat said.
