The role of the Quartet is to support the Middle East Peace Process. It does not have a formal policy towards Iran. However, the Quartet has said that it supports the efforts of responsible regional states to help calm the situation, and will continue to promote a negotiated, comprehensive, just and lasting Middle East peace in line with relevant UN Security Council Resolutions. It has urged all states in the region to work closely with Mr. Blair to this end and encouraged robust international support for his efforts.
