EIFF artistic director Hannah McGill said the festival will screen Moroccan documentary Transes and Brazilian feature Limite, both restored by the foundation (Limite will be presented partially restored).
The screenings are the first public showings of WCF restorations after the foundation was launched in Cannes this year.
Ahmed El Maanouni's Transes, from 1981, is a documentary about Moroccan musical group Nass El Ghiwan. It will play EIFF on Aug 20.
Mario Peixoto's Limite, from 1931, is a simple story about three people adrift on a boating trip. It screens on Aug 22.
'We are fervent supporters of the WCF,' McGill said. 'The EIFF stands for everything the Foundation is setting out to do and takes pride in our shared interest in promoting world cinema. We're excited to provide an international stage for the Foundation's first public screenings and look forward to a fruitful partnership with the WCF for years to come.'
