The upcoming Moscow meeting of the Middle East Quartet comes at a "crucially important" time for talks between Israel and the Palestinian authorities, UN Secretary General Ban Ki-moon has told RIA Novosti.

Ban arrives in the Russian capital on March 17, two days ahead of the meeting of the Quartet of international mediators in Israeli-Palestinian peace talks. The Quartet is made up of Russia, the UN, the United States and the European Union.

"I appreciate, first of all, and highly commend the initiative and leadership of the Russian government to host the Quartet meeting at this time," Ban said in an exclusive interview. "This is crucially important timing for the peace process in the Middle East."

Ban noted that with "proximity talks" being facilitated by the U.S., "it is very opportune timing for the principles of the Quartet to express their support and to encourage further, to try to find out what kind of role the Quartet can play."

"I''m quite convinced that this time the Quartet leaders will be able to play a significant role," he added.

Russian Foreign Minister Sergei Lavrov, U.S. Secretary of State Hillary Clinton, and EU Foreign Policy chief Catherine Ashton are also scheduled to attend the March 19 meeting in Moscow.

Ban will also meet with Russian President Dmitry Medvedev during his visit to Russia.
