<span style="color: #222222;">Turkey today said it does not fear US sanctions over its decision to buy a Russian missile defence system that has frayed ties between the NATO allies.</span><br />'' <span style="color: #222222;"><br />'' The United States has given Turkey a deadline of July 31 to drop the purchase of the S-400 system, or face sanctions and removal from its F-35 fighter jet programme. Turkey Foreign Minister Mevlut Cavusoglu told reporters in Ankara that regardless of whatever sanctions there may be, they have bought the S-400. </span><br />'' <span style="color: #222222;"><br />'' He said Turkey is working on the date for the system's delivery, which President Recep Tayyip Erdogan has said would be in the first half of July.</span><br />'' <span style="color: #222222;"><br />'' Cavusoglu said Turkey will no longer allow other countries to dictate its defence purchases. Relations between Washington and Ankara have deteriorated over multiple issues, including the S-400 deal and US support for a Syrian Kurdish militia viewed as terrorists by Turkey.</span><br />'' <span style="color: #222222;"><br />''<br />''Sanctions could cause damage at a time when Turkey's economy is already struggling. Its currency lost a third of its value last year, in part due to temporary US sanctions over the detention of an American pastor.</span><br />
