(25)Collaboration between the enforcement authorities of the Member States is necessary in ensuring the attainment of the protection objectives of this Directive. It is, therefore, appropriate to promote the operation of a European network of the enforcement authorities of the Member States to facilitate, in a coordinated manner with other Community procedures, in particular the Community Rapid Information System (RAPEX), improved collaboration at operational level on market surveillance and other enforcement activities, in particular risk assessment, testing of products, exchange of expertise and scientific knowledge, execution of joint surveillance projects and tracing, withdrawing or recalling dangerous products.
