Thai soldiers carry national flags as they participate in the opening ceremony of the annual joint "Cobra Gold 2010" (CG10) military exercise at U-tapao airport in Rayong province in this February 1, 2010 file photo. The United States will invite Myanmar to the world's largest multinational military field exercise, a powerful symbolic gesture toward a military with a grim human rights record and a milestone in its rapprochement with the West. Myanmar will be allowed to observe Cobra Gold, which brings together more than 10,000 American and Thai military personnel and participants from other Asian countries for joint annual manoeuvres, officials from countries participating in the exercises told Reuters.
