The United States has proposed a 12-point plan to stimulate resumption of negotiations for a Cyprus solution, the State Department said yesterday.

Department spokesman Hodding Carter stressed that the proposals are "not a comprehensive American plan." but rather "suggestions intended to be helpful" in getting new talks started between the Greek and Turkish communites on Cyprus and their respective patrons, Greece and Turkey.

Carter said a Turkish-language version of the proposals published in the Turkish press is substantially correct. Its main provisions suggest dividing the island republic into separate Greek and Turkish regions under a federal government with limited powers, and the return to Greek Cypriots of significant territory seized by Turkey after its 1974 invasion.

The invasion, which followed an abortive corp by elements of the majority Greek community, resulted in Turkey occupying about 37 percent of the island with large-scale disruptions of its population patterns.

Turkey's refusal to withdraw led Congress to impose an embargo on U.S. arms shipments to Turkey. Last summer, over the bitter opposition of Greece and the Greek-American community President Carter convinced Congress to lift the embargo.

Since the administration argued that repeal of the embargo was necessary to get Turkey to negotiate on a settlement, Washington now is under pressure to get meaningful talks underway. Hodding Carter said yesterday that the United States has not received any formal responses to its proposals from any of the parties involved.
