Israeli Prime Minister Ehud Olmert and president Mahmud Abbas began meeting in Jerusalem on Monday, their first encounter in three weeks, officials said.
Abbas's motorcade arrived from the Palestinian political capital of Ramallah at the premier's official residence in the centre of Jerusalem amid heavy security.
During Monday's meeting, the first between Abbas and Olmert since a June 25 four-way summit in Egypt, Israel will insist on security issues while the Palestinians will focus on the wider peace process, officials said.
"We want the Palestinian Authority to prove that they are fighting terror, this is the key," Israeli government spokeswoman Miri Eisin said.
Chief Palestinian negotiator Saeb Erakat said: "The main subject on which president Abbas will insist is a political horizon for the peace process and the start of negotiations on a final status agreement."
