Contrary to the above-mentioned guidelines, several CoE member states do not impose any restrictions on foreign contributions (e.g. Austria, Belgium, Denmark, Italy, Luxembourg, the Netherlands, San Marino, Sweden). Irrespective of the specific reasons for not doing so, the lack of restrictions might be not seen as problematic as long as there is no necessity to prevent undue foreign influence on political parties and electoral campaigns. Counterexamples include some Central and Eastern European countries where the processes of nation building and/or democratisation in the 1990s were accompanied by concerns of undue foreign influence on the national political development, justifying prohibitions.
