DHAKA (AFP) - Bangladesh said Thursday it has asked a UN tribunal to resolve a decades-old row with neighbours Myanmar and India over gas-rich waters in the Bay of Bengal. The move comes almost a year after a tense stand-off when Myanmar escorted a South Korean exploration company into a disputed segment of the bay. A similar incident with an Indian vessel occurred just weeks later. Bangladeshs foreign minister, Dipu Moni, told reporters she had summoned envoys from India and Myanmar to inform them Dhaka had requested the dispute be settled under the United Nations Convention on the Law of the Sea (UNCLOS). This matter has been going on for more than 35 years now with no significant resolution, she said. By launching this arbitration we will not hamper the friendly relations we share with our neighbours. The Bangladeshi government has granted the right for US energy giant ConocoPhillips to explore two blocks in the bay and another to Irish company Tullow, despite competing ownership claims. Moni said no exploration would begin before the arbitration process was completed. Experts have forecast major reserves of gas in the Bangladesh areas after huge discoveries in the Myanmar and Indian zones.
