Greek Cypriot President Demetris Christofias said on Tuesday he was prepared to open ports and airports to commercial activities run by Turkish Cyprus from the northern half of the divided island.
"The Republic of Greek Cyprus offers our compatriot Cypriot Turks who wish to export and import goods, to trade through the free ports and airports of the Republic of Greek Cyprus," he told a meeting of the Council of Europe.
Reuters reported him as saying "this is a full official declaration I am making before you."
The offer comes as the Turkish and Greek sides have been working on a deal to reunify Cyprus, which was split after a brief Greek-inspired coup, triggering a Turkish intervention in 1974.
In 2004, EU accepted Greek Cyprus as a member despite the division of the island.
Turkey has 30,000 troops in northern Cyprus to prevent any conflicts on the island.
