Turkey has introduced a rule that municipalities, special provincial administrations and related entities must now use at least 51% domestic goods when manufacturing subways, light rail systems, trams and similar vehicles.

Provisions in secondary legislation which prevent domestic production and provision of domestic services will no longer apply.

Under the new rules, these entities must also take all measures possible to encourage domestic production, in order to expand use of domestic products and services during tenders and other domestic production and procurement projects.

The Prime Ministry published Circular No. 2017/22 in Official Gazette number 30233 on 7 November 2017. Please see this link for the full text of the Circular (available only in Turkish).
