Arab League Secretary General Nabil Al-Arabi arrived in Ramallah Saturday for a visit to the West Bank, an AFP correspondent said.
Arabi will be joined by 10 Arab foreign ministers, according to the Palestinian Authority's (PA) top diplomat Riyad Al-Malki.
Chief Palestinian negotiator Saeb Erakat said last week he expected the League would imminently pay the first installment of a promised fiscal "safety net" of $100 million, promised in the event of Israeli financial sanctions on the PA.
On 2 December, Israel said it would not transfer tax and customs funds it collects for the Palestinians this month in response to their successful bid for upgraded UN observer state status.
Every month, Israel transfers about 460 million shekels ($120 million) in customs duties on goods destined for Palestinian markets that transit through Israeli ports, and which constitutes a large percentage of the Palestinian budget.
The transfers are governed by the 1994 Paris Protocols.
