Russia ready to sign new deal with Turkey on S-400s

Russian Deputy Prime Minister Yuri Borisov said on Wednesday that Russia is ready to ink a new deal with Turkey on the delivery of more S-400 air defence missiles, TASS news agency reported.

"They have such an option and we will sign the deal, if they express the desire," Borisov said.

Turkey’s decision to acquire S-400 missiles has soured its relations with the United States, which halted the delivery of 100 F-35 fighter jets to Turkey and suspended Turkey’s participation in the F-35 production programme after the first shipment of the Russian defence system arrived in Turkey in July.

The United States maintains the S-400s are incompatible with NATO's defence systems and could allow Russia access to sensitive data through subterfuge.
