AEC was established to increase bargaining power and the capacity of ASEAN on the international stage. The product of each country in ASEAN have several type such as Agriculture and fisheries of Myanmar, rubber products sectors and textile fields of Malaysia, in movies and in wood products of Indonesia, electronic field of Philippines, the information technology field and health of Singapore, and tourism, and the aviation (Thailand: Thailand is in the middle ASEAN) and etc. Respectively, what we should be prepared early which is English language at least we will have a communication business. If communication is not otherwise you would not have to do anything. If you are a customer in Thailand, it just may not be enough. Due to foreign businesses will also vie for market share of the AEC is certainly a big deal. Thailand on business and people has to adapt and prepare well.
