Shortly after Malta gained its independence in 1964, the Swiss ambassador in Rome was accredited by the Maltese government. The Swiss honorary consulate in Valletta, first established in 1937, was upgraded to an honorary consulate general in 2003. A Maltese ambassador (with residence in Malta) has been accredited to Switzerland since 2008.
Switzerland and Malta jointly founded the Mediterranean Academy for Diplomatic Studies (MEDAC) in 1990.
