• The Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation (BIMSTEC) is an international organisation involving a group of countries in South Asia and South East Asia. These are: Bangladesh, India, Myanmar, Sri Lanka, Thailand, Bhutanand Nepal.
• BIMSTEC uses the alphabetical order for the Chairmanship. The Chairmanship of BIMSTEC has been taken in rotation commencing with Bangladesh (1997–1999), India (2000) Myanmar (2001–2002), Sri Lanka (2002–2003), Thailand (2003–2005), Bangladesh (2005–2006). Bhutan asked for the skip due to some political problem. So it’s turned to India (2006–2009).
• In November 2009, Myanmar hosted the 12th Ministerial Meeting and assumed BIMSTEC Chairmanship.
• The 13th Ministerial Meeting also chaired by Myanmar, which was held in Nay Pyi Taw, Myanmar on 22 January 2011. Nepal formally took over the new Chairmanship as on 4 March 2014. Sumith Nakandala of Sri Lanka became the first Secretary General of BIMSTEC.
