Affairs of the Kingdom The Charter states explicitly which elements of lawmaking and policy that involve Aruba, Curaçao and/or Sint Maarten are to be dealt with on the level of the Kingdom as a whole and are thus valid for all four countries. Any matter not explicitly mentioned to be an affair of the Kingdom that involves Aruba, Curaçao, and/or Sint Maarten is considered to be an affair of the different countries. Affairs of the Kingdom that do not involve Aruba, Curaçao and/or Sint Maarten are dealt with according to the provisions of the Constitution for the Kingdom of the Netherlands, and in practice by the Netherlands alone in its capacity as the Kingdom of the Netherlands. Responsibility for affairs of the Kingdom that involve Aruba, Curaçao and/or Sint Maarten rests with the Council of Ministers of the Kingdom. The affairs of the Kingdom are: maintenance of the independence and the defence of the Kingdom; foreign relations; Netherlands nationality; regulation of the orders of chivalry, the flag and the coat of arms of the Kingdom; regulation of the nationality of vessels and the standards required for the safety and navigation of seagoing vessels flying the flag of the Kingdom, with the exception of sailing ships; supervision of the general rules governing the admission and expulsion of Netherlands nationals and aliens; extradition. Other provisions In addition, the Charter contains provisions on mutual assistance and co-operation between the four countries. All four countries are, per the Charter, obliged to promote the realisation of human rights and good governance. The Charter can only be amended with the approval of all four countries.
