MOSCOW, April 5 (RIA Novosti) - Palestinian President Mahmoud Abbas is arriving in Moscow on April 5 on a four-day working visit to discuss the situation in the Middle East, a Kremlin source said on Sunday.

"One of the priority tasks at the current stage is to create conditions for the resumption of the negotiation process, which will be facilitated by an international conference on the Middle East intended to be held in Moscow this year," the Kremlin source said.

The parties will also discuss the prospects of restoring the Palestinian unity required for the success of the negotiation process and the establishment of Palestine as a viable independent and democratic state co-existing in peace and security with Israel, the Kremlin source said.

The Palestinian leader is arriving in Moscow at the invitation of Russian President Dmitry Medvedev.

Talks between Israel and the Palestinian Authority, launched by then-U.S. president George Bush in November 2007 at a conference in Annapolis, Maryland, stalled over outbreaks of violence in the Middle East, as well as long-standing disputes over the construction of Jewish settlements and the future status of Jerusalem.
