The influence of the EU is also felt through the enlargement. The potential benefits of becoming a member of the EU act as an incentive for both political and economic reform in states wishing to fulfil the EU's accession criteria, and are considered a major factor contributing to the reform and stabilisation of former Communist countries in Eastern Europe. This influence on the internal affairs of other countries is generally referred to as "soft power", as opposed to military "hard power". An example of the support the European Union offers to the reform processes of its neighbours is EUBAM, the European Union Border Assistance Mission to Moldova and Ukraine, which assists the governments of Moldova and Ukraine in approximating their border and customs procedures to EU standards.
