English has been increasingly used in Thailand as a lingua franca; that is, a means of communication between people who do not share a mother tongue nor speak English as a native language. Given the integration of ASEAN nations to form an economic region, the use of English as lingua franca (ELF) in Thailand and other member states of ASEAN will likely continue to increase at a significant rate. Kagnarith, Klein and Middlecamp (2012) observe that the increasing use of English as an inter-regional language of communication probably results from two causes. First, the use of English as ASEAN's working lingua franca has already been in effect. Second, the promotion of English as an international business language is one objective of the plan for the regional integration of the ASEAN Economic Community (AEC). In fact, the campaign to promote English as an official lingua franca in ASEAN is based on Article 34 of The ASEAN Charter ratified in February 2009: ‘The working language of ASEAN shall be English’.
