The Concordis International team has been active in various forms since 1987, as an international initiative of the Relationships Foundation.

Until 1999, the Relationship Foundation's international work bore the name Newick Park Initiative (NPI) after the home of Viscount Brentford, Chairman of NPI, where the earlier consultations took place.  From 1999 to its formation as a separate charity in 2004, it was known as Relationships Foundation International (RFI), reflecting its status as an integral part of the parent organisation.

• South Africa 1987 - 1991
  The initiative helped establish informal and confidential dialogue between leading members of the ANC and the white establishment. The first consultation was held in Britain in March 1987, while there was a state of emergency in South Africa under President P W Botha and almost no contact between the ANC and the Government. Overall, NPI held 10 consultations over a four year period, with a gradual increase in the seniority and influence of those attending. A total of 91 research papers were made available to participants on a wide range of economic, social and political issues. Several of these papers are said to have helped resolve some of the major stumbling blocks in the negotiations between the ANC and the Government.
  
  
• Rwanda 1994 - 1997
  Following the 1994 genocide, the Concordis International team (as NPI) played an important role in getting agriculture moving as a means of preventing further conflict, and contributed towards the establishment of the gacaca system of local courts as a way of resolving the problem of 130,000 adults accused of genocide.
  
  
• Sudan 1999 - today
  The Concordis International team, by then known as Relationships Foundation International (RFI), joined with the African Renaissance Institute (ARI) in 1999 to begin the Sudan Peace-Building Programme at the invitation of senior Sudanese individuals. Six consultations were held between January 2001 and July 2003. By providing a forum where leaders can meet informally and discuss key issues, the programme has contributed to a greater willingness on all sides to lay down weapons, to finding constructive solutions to points of difference and thus to the success of the formal peace talks.
  
  Subsequently, Concordis International has re-focused on facilitating informal dialogue across the wide spectrum of Sudanese society. Overall, the process strengthens the formal Track 1 peace process by facilitating convergence of the positions of all political parties, the private sector and civil society - horizontally (across the lines of conflict) and vertically (within their own constituencies) - with a view to long-term transformation of relationships. To date, Concordis has facilitated a further fifteen regional and national Sudanese consultations on this basis.
  
  
• Afghanistan 2003 - today
  Background research and a detailed assessment of conflict in Afghanistan was undertaken in 2003, prior to a visit to Afghanistan in January 2004 by the Chief Executive and the Programme and Research Manager. The need for a consultation programme had been confirmed, subject to funding and political developments. It seems probable that the first consultation will be concerned with looking for viable alternatives to the opium poppy, encouraging Afghans to pursue legal and sustainable farming practices.
  
  
• The Democratic Republic of the Congo 2005 – today
  Background research and preliminary visits have been undertaken to assess future participation in the Democratic Republic of the Congo. Concordis has met with a number of politicians and civil society organisations who would very much welcome the long-term engagement of an organisation not associated with the DRC's colonial past and willing to work with people from across the spectrum of public, private and voluntary sectors. Concordis' activity would contribute towards nation-building by encouraging national dialogue and consensus on practical policy initiatives. Future work in the DRC depends on the availability of funding.
  
  
• Elsewhere in the World
  Preliminary enquiries and background research have been undertaken for future possible programmes in other conflict areas, including southern Africa and the Middle East. A small-scale dialogue between UK-based Israelis and Palestinians, organised on areas of common interest, took place in October 2004. However, involvement in these areas will depend on many factors, including the availability of funding.
