At the end of the 1970s, with the spread of the Movement, a greater openness towards agnostics, atheists, the indifferent, and people without formal faith, reached the point of expressing itself in a dialogue with its own particular features. Unity also means having deep respect for human dignity, identity, culture, human needs and beliefs. With this in mind, in 1978 the "International Centre for Dialogue with People of Non-Religious Beliefs" was created. In 1992, the first international conference was organized, which has been held periodically since then. In 1995 in Loppiano, then in 1998 in Castel Gandolfo, Chiara began a "dialogue with people of non-religious beliefs". In these conferences Chiara invited them to collaborate in the realisation of universal fraternity.

In St Peter’s Square, Rome, on May 30 1998, Chiara was among the four founders who spoke at the first international meeting of ecclesial movements and new communities. Over 350,000 people took part. Thanking the Pope for the support received over time, she addressed John Paul II with a promise: “We know that the Church desires full communion among movements, and their unity which, moreover, has already begun.

In Strasbourg (France) she addressed the 50th Anniversary Conference of the Council of Europe with a talk on "Market Society, Democracy and Solidarity", presenting the experience of the Economy of Communion as a proposal for new economic activity. In Speyer (Germany), she met the founders and leaders of 41 ecclesial movements and new communities, at a conference organised together with the Community of S. Egidio and Renewal in the Spirit (Italy); John Paul II sent a message of support. In Augsburg, Germany, she attended the historic ceremonial signing of the Joint Declaration on the Doctrine of Justification and met with leaders of the Lutheran World Federation. On November 29, 1999, she spoke at the VII Assembly of the World Conference of Religions for Peace in Amman, with some reflections and experiences on the theme "A Spirituality for Common Living".
