The INCP Liaison Bureau is the body accountable to all INCP members. Its role is to respond to information requests, prepare research papers which provide issues for consideration by Ministers at their annual meeting, coordinate the annual Ministerial Meeting with the host country, plan and initiate the Contact Group Meetings as well as represent the INCP in its different Working Groups and international fora such as UNESCO. The Liaison Bureau is currently housed by Canada following a decision made at the INCP's 2nd annual Ministerial Meeting.

The Liaison Bureau also handles routine administrative matters for the INCP including; maintaining an accurate list of INCP countries and their respective cultural ministers and officials, welcoming new member countries to the INCP, distributing all important INCP documents to member countries and updating the official INCP web site.
