Its major suppliers have traditionally been the United States and Europe, but more recently Turkey has turned to Russia for the purchase of a missile defence system.
So which countries have imposed bans and where does that leave Turkey to buy its weapons from?
Who has imposed bans?
Nine European countries have imposed controls on arms sales to Turkey.
The Czech Republic, Finland, France, Germany, Italy, the Netherlands, Spain, Sweden, and the UK have all – along with Canada – announced they are halting or restricting arms export licence approvals for Turkey.
UK Foreign Secretary Dominic Raab has said Britain would continue selling arms to Turkey but would not grant new export licences for weapons which might be used in military operations in Syria.
Germany and Spain have said that their embargoes only apply to new contracts.
The European Union has not endorsed an official EU-wide arms embargo, although foreign ministers have agreed to adopt “strong national positions regarding their arms export policy to Turkey”.
“The arms sanctions are not expected to have a great effect, if any, on Ankara’s operation should it continue,” says defence analyst Yvonni-Stefania Efstathiou.
But “should sanctions extend beyond weapons potentially used in Syria”, she says, “there could be a negative impact on Turkey’s overall defence industry”.
Who are the major arms suppliers to Turkey?
Over the period 1991-2017, Turkey was the world’s fifth largest importer of major weapons.
Turkey has historically relied on its Nato allies in the United States and Europe for its defence and security needs.
The US has been the largest exporter of arms to Turkey, providing 60% of its total imports between 2014 and 2018.
Among European countries, France, Spain and the UK have been major suppliers.
