The Turkish defense company Baykar had sold the drones to Kyiv despite Russian objections and signed an agreement to co-produce more before the invasion, angering Moscow. NATO member Turkey shares a maritime border with Ukraine and Russia in the Black Sea, has good ties with both and has taken on a mediating role in the conflict.

While supporting Ukraine and criticizing the Russian invasion, Turkey has also opposed the extensive Western sanctions on Moscow, saying the channels of communication must remain open and questioning the effectiveness of the measures. Ankara also opposes Russian policies in Syria and Libya, as well as the annexation of Crimea in 2014.

The bureaucrat said some countries on the list would treat “legal issues” as security guarantors, without giving further details. Turkey has stated that it is ready, in principle, to be the guarantor of Ukraine, but the details of the form must be finalized. read more Sign up now for FREE unlimited access to Reuters.com Register Report by Jonathan Spicer.
