1. Member States shall, with the assistance of the Commission, take accompanying measures to develop, facilitate and promote the exchange between officials in charge of the implementation of administrative cooperation and mutual assistance as well as monitoring the compliance with, and enforcement of, the applicable rules. Member States may also take accompanying measures to support organisations that provide information to posted workers.

2. The Commission shall assess the need for financial support in order to further improve administrative cooperation and increase mutual trust through projects, including promoting exchanges of relevant officials and training, as well as developing, facilitating and promoting best practice initiatives, including those of social partners at Union level, such as the development and updating of databases or joint websites containing general or sector-specific information concerning terms and conditions of employment to be respected and the collection and evaluation of comprehensive data specific to the posting process.

Where it concludes that such a need exists, the Commission shall, without prejudice to the prerogatives of the European Parliament and the Council in the budgetary procedure, use available financing instruments aimed at strengthening administrative cooperation.
