Officials at the museum said the two sides have chosen the common issue of protecting wooden remains as the starting point for their cooperation. Both the museum and the Notre-Dame Cathedral in Paris have extensively used wooden materials and have fire-damaged wooden remains.

The research on protecting wooden remains will involve joint efforts to preserve and restore the fire-damaged wood from the two world cultural heritage sites. It will also include wood species identification, preservation status assessment, degradation mechanisms, and protection techniques and methods, the officials said.
