ISTANBUL (Reuters) -- Turkey will not open its ports and airports to Greek Cypriot ships and planes, a key step in its European Union membership bid, until the bloc establishes trades ties with Turkish Cypriots, the chief EU negotiator said on Thursday.

Deputy Prime Minister Egemen Bagis also told reporters a temporary delay in UN-brokered peace talks on Cyprus this week demonstrated Greek Cypriots' lack of commitment to resolving the island's 35-year division.
Turkey agreed to open its ports to Cyprus, a member of the EU, before the end of this year to meet the union's customs rules or risk derailing its membership bid. The ports were shut in 1987, Bagis said.
“There are certain expectations that we will reopen our ports, but there are guarantees Turkey must receive to meet these expectations that have to do with ending the isolation imposed on Turkish Cyprus,” Bagis said.
“Until EU countries begin direct trade with Turkish Cyprus and land their planes at (its) airport, I don't find it sincere or believable that Greek Cypriot planes and ships can use our airports and harbors,” he said.
Greek Cypriot officials said on Thursday they expected reunification talks with Turkish Cypriots to resume next week after they cancelled Thursday's scheduled talks after more than 500 pilgrims were barred from visiting a church in the north.
“I think the decision taken by the Greek Cypriot administration (to cancel talks) again shows how determined they are to block a resolution,” Bagis said.
The talks began in September 2008. The United Nations and European Union want to see progress this year, worried about Turkey's EU prospects and Turkish Cypriot elections in 2010.
