The increasing international character of cities and regions within the AA due to global trade, eastward expansion of the EU, emigration and low cost airlines, dictates the need for public authorities to develop e-services which are multilingual, inter-operable and which support citizens, workers and businesses both at home and while travelling. Regions, cities and their public authorities also recognise the need to develop tangible transnational products and services that will lead to a more cohesive AA.
