Malaysia and Singapore relations are special and unique due to things such as Geography, History, politics, ideology, economy, culture and ethnicity. These factors have sometimes created some tension between both countries. The uniqueness of the relationship may be reflected by the various terms used to describe the state of the rivalry or family quarrel such as 'Siamese Twins' suggesting a common love-hate relationship that has grown out of a shared common history and cultural background, coloured by political differences and by economic competition and interdependency.
