Türkiye says it will not submit to US "impositions".

Reuters Turkey's Foreign Ministry said on Wednesday that Ankara will not submit to "impositions" from the United States to resolve a crisis that has led the two NATO allies to stop issuing visas to their respective citizens.

But the spokesman for Turkish President Tayyip Erdogan struck a more positive tone, saying he believed the crisis would be resolved quickly after a US delegation arrived in his country to discuss how to repair bilateral relations.

Earlier this month, Washington suspended visa services after Turkey detained two Turkish citizens employed at the U.S. consulate. They are being held on suspicion of links to the failed coup attempt in Turkey last year, allegations rejected by Washington.

Ankara quickly retaliated by suspending its own visa issuance services for the US. The dispute affected the Turkish lira and stocks and worried investors.

The US said it wants details of the charges against the consular officials, and the Turkish broadcaster Haberturk reported that the US delegation set four conditions for resolving the crisis, including that Ankara present evidence related to the detentions.

"We will cooperate if their demands comply with the rules of our Constitution, but we will not succumb to impositions and will reject any conditions that we cannot meet," said Turkish Foreign Minister Mevlut Cavusoglu at a press conference on Wednesday.
