(4) The decision of Member States to participate in PESCO is voluntary and does not in itself affect national sovereignty or the specific character of the security and defence policy of certain Member States. Contributions by the participating Member States to fulfil the more binding commitments under PESCO will be made in accordance with their applicable constitutional provisions. (5) Increasing joint and collaborative defence capability development projects, is among the binding commitments under PESCO. Such projects may be supported by contributions from the Union budget in compliance with the Treaties and in accordance with relevant Union instruments and programmes. (6) The participating Member States have set out in their respective National Implementation Plans their ability to meet the more binding commitments they have made to one another. (7) The necessary conditions having been met, it is therefore appropriate for the Council to adopt a decision establishing PESCO. (8) Any other Member State which wishes at a later stage to participate in PESCO may notify its intention to do so to the Council and to the High Representative in accordance with Article 46(3) of the TEU. (9) The High Representative will be fully involved in proceedings relating to PESCO. 14866/17 JU/jk DGC 1C 3 EN
