[10] In September 2007, Mamberti orchestrated the first official visit between an Arab Head of State, Sudan's President Omar el-Bashir and Pope Benedict.

"The visit of (Archbishop) Mamberti also showed the favourable development of relations between the state and the Catholic Church in Cuba," the government's note said.

He added that the Vatican viewed the Palestinian bid "in the perspective of efforts to find a definitive solution" to the Israeli-Palestinian question – an issue addressed by a U.N. resolution of 1947 that foresaw the creation of two states.

He called the UN delegates' attention to the language of the UN Charter and the Universal Declaration on Human Rights, which affirm the importance of the natural law.

"Such will be possible," he said, "if legislation at the international level is marked by respect for the dignity of the human person, beginning with the centrality of the right to life and to freedom of religion.

"[12] In a separate address in early October 2012, Mamberti spoke of the theme of the assembly as the "Adjustment or settlement of international disputes or situations by peaceful means."

Archbishop Mamberti referred specifically to situations in the Middle East, particularly in Syria, "A solution is impossible if it fails to respect the rules of international and humanitarian law, or falls outside the mechanisms established in the United Nations Charter," he stated.

"All interested parties should not only facilitate the mission of the special envoy of the United Nations and the Arab League, but also ensure humanitarian assistance to the suffering peoples.

The international community must unite its efforts so that all sides replace the race to arms with negotiation, just as it must insist on effective respect for religious liberty, human rights and all fundamental freedoms.

[14][15] In July 2014 commenting on the situation in Gaza, Mamberti sent a formal note to all the ambassadors accredited to the Holy See, calling their attention to the appeals by Pope Francis for Christians in Iraq and elsewhere in the Middle East.
