Did Turkey face international condemnation for it's intervention? Were any sanctions imposed or UN resolutions?
-
United Nations Security Council Resolution No 360, 16 August 1974; formal
disapproval of the unilateral military actions of Turkey against "Cyprus". (Note that in this resolution permanent member USSR, non-permanent members Iraq and Byelorussia were absent and permanent member China did not participate)
-
United Nations Security Council Resolution No 367, 12 March 1975; unilateral declaration of a "Federated Turkish State". This one was adopted without vote
-
United Nations Security Council Resolution No 541, 18 November 1983; proclaiming that the Turkish Cypriot UDI was illegal and requesting that no other sovereign state should recognize the legality of the declaration and asked for its withdrawal.(Note that only Pakistan was against this resolution as non-permanent member, and Jordan was absent during the voting process as non-permanent member)
-
United Nations Security Council Resolution No 550, 11 May 1984; the Council condemned the illegal secessionist activities in "the occupied part" of the Republic of Cyprus from Turkey, in violation of the previous resolutions.( Again, Pakistan was against the resolution as non-permanent member, and United States was absent during the voting process as permanent member)
There are many more resolutions concerning Cyprus but these ones, imho, are the most important ones.
Your other part of the question; U.S. Congress imposed an embargo on arms sales to Turkey back then but the arms embargo was silently removed a few years later.
