(Mancham is also reported as scheduled to attend the opening of the World Future Council, which has no Moon connection)

The Global Peace Council has also wooed a former president of Vanuatu, as was reported in 2005:

Former head of state George Sokomanu is currently in New York, where he is attending the first assembly of the Global Peace Council under sponsorship of the Interreligious and International Federation for World Peace (IIFWP).

...The Peace Council for Oceania was founded in 2004 in Samoa with Mr Sokomanu, Pastor Pakoa Maraki (then secretary general of Vanuatu Christian Council VCC) and then speaker of parliament, Roger Abiut, all representing Vanuatu.

... Sokomanu was not only the former president of the republic of Vanuatu, he has also held the post of Secretary General of the South Pacific Community (SPC). Currently, in addition to other duties, he is serving as the chairman of ambassadors for Peace Vanuatu...

Meanwhile, a Unificationist website notes the involvement of a former Albanian head of state:

...Prof. Dr. Rexhep Mejdani (Former President of Albania) who is member of Global Peace Council was invited to the stage to welcome Father and Mother Moon to Albania. He is very popular politician in our country therefore his word was very important. In a surprising finish, he concluded his remarks by reciting the Crown of Glory, a poem written by Father Moon when he was just fifteen. Dr. Mejdani himself had even tried to translate it and make it fit to Albanian language.

An ad for a book about Moon, entitled Peace King, rounds up a few other presidential admirers:

Presidents, prime ministers, scientists, Nobel laureates, religious leaders, novelists and men and women from all walks of life and from all corners of the world share how they have been impacted by coming to know Rev. Dr. Sun Myung Moon, the Peace King... This project was inspired by the suggestion made by President of the Republic of India, Dr. A.P.J. Abdul Kalam.

..."Rev. Moon is a teacher. But not an ordinary teacher. Rev. Moon is a messenger. But not an ordinary messenger. The truth is that the Rev. Moon is a prophet of our time."
Kenneth Kaunda
President, Zambia (1964-1991)

..."Rev. Moon's call for peace though religion is something of great nuance and profundity. We are deeply fortunate for the chance to hear him and observe his life-long struggle for world peace."
H.E. Abdurrahman Wahid
President, Indonesia (1999-2001)

Prime ministers are also part of the vision - the late UK PM Ted Heath was famously an admirer, and recently former Zambian PM Malimba Masheke was on hand to greet Maria Sung, the wife of former Archbishop Milingo, to his country. Masheke chairs Moon's International Inter-religious Federation for World Peace.

An interesting 2001 essay that looks at Moon's NGO strategies can be seen here.
