ABC plan (also known as the Nimetz initiative) was a proposed settlement of the Cyprus dispute, presented by the USA but co-authored by Britain and Canada as well, hence the abbreviation ABC (American-British-Canadian). The settlement was proposed in 1979. It projected a loose federation between the Greek and Turkish community of Cyprus and it was based on previous agreements between Greek and Turkish Cypriot leaders, and UN resolutions. It was rejected by all sides.
The plan consisted of twelve points, according to Eleftherios Michael most important were:
The central federal government would be in charge of Foreign Affairs, Defence, finance and economy, ports, customs controls and immigration.
Newly elected Greek Cypriot president Spyros Kyprianou was fast to reject the plan, Turkey followed. Even so, the Nimetz initiative was utilized by other UN general secretaries as a base to new plans.
