Since 2018, international cooperation has been one of the statutory missions of the Inp. The establishment has defined an international strategy for the years 2019 to 2022 which highlights the geographical priorities and specifies the modes of action envisaged as well as the partners of these projects.

In 2021, the Inp consolidated its position as an operator at the service of French cultural diplomacy through its educational activities, its engineering missions and the training of heritage professionals, in close partnership with the Ministry of Culture and in growing collaboration with the Ministry for Europe and Foreign Affairs.

In 2021, Inp's international cooperation experienced a ramp-up, with around fifty international actions prepared concurrently. International actions in unstable countries or in conflict zones have developed, in particular thanks to the support of ALIPH (the International Alliance for the Protection of Heritage in Conflict Zones). Human resources for international relations were strengthened by two successive internships and then recruitment on a project contract.

Despite the pandemic, important actions have been taken and international promotion has always been able to continue. The health situation has nevertheless had an impact: a training cycle in Morocco planned from December 2021 has been postponed to 2022, training in Lebanon has been delayed and adapted.
