In 2011 EMA’s biennial General Assembly (GA) in Mestre, Italy, accepted the memberhips of Poland and United Kingdom, bringing the current membership to 16 countries.

EMA was founded in 2005 during the first Open European Mahjong Championship (OEMC) in Nijmegen, the Netherlands. The 'founding members' were: Austria, Denmark, France, Germany, Hungary, Italy and the Netherlands.

In 2008 Finland, the Russian Federation, Slovakia, Spain and Sweden applied for the EMA membership, followed in 2009 by Belgium and Portugal. All organizations were admitted during the GA of 2009 in Baden, Austria.

The EMA is registered at The Central Business Register in Denmark (CVR: det centrale virksomhedsregister) at The Danish Commerce and Companies Agency (Erhvervs- og Selskabsstyrelsen).

The purpose of the association is to encourage, disseminate and coordinate the playing of mahjong in Europe. The association is a non-profit organization with no political or religious purpose.

European Mahjong Association celebrates its 10 year anniversary this summer.

In these 10 years EMA has grown from the original 7 members to the 19 countries we are today.
The number of tournaments has grown and grown. The ranking lists for both MCR and riichi are evidence of the many active players.  EMA has  established the EMA riichi rules, kick-starting EMA riichi tournaments and regular European Riichi Championships. EMA is educating and certifying referees which is essential for the successful high-level tournaments.

The EMA General Assembly 2015 will take place in Copenhagen on May 15, 9am-11:30am, in connection with a 9 session MCR tournament 15-17 May.

At the General Assembly each country can send two representatives.
