The Archive has collaborated with international film bodies towards preserving both Chinese and international films. One such project was the archive's collaborative effort with the British Film Institute and with Thailand's national archive - the Thai Film Archive - towards restoring the award-winning Thai film, "Santi-Vina" (1954). A copy of the film from the Archive was donated to Thailand for restoration efforts, as China had previously bought a copy of the film during its original release at the Southeast Asian Film Festival. However this copy of the film was used as a guide, with another copy of the film from the Russian Organisation Gosfilmofond, utilised as the negatives which were digitally scanned and cleaned. This is as the Archive's copy had two missing scenes, a ‘magenta hue’ and Chinese subtitles burned into the negatives. However, the Archive's film was used as a guide, as the negatives of the copy from Gosfilofond had shrunk by 0.4%. The film was digitally restored by the L'Immagine Ritrovata laboratory. After its restoration, it premiered at the 2016 Cannes Film Festival, in the ‘Cannes Classics’ section alongside other international films. This was notable as it was the first Thai film to be selected into this category.
