Representatives of the United Nations and the Congolese national army met with a band of LRA thought to be under the command of Vincent Otti in northeastern DRC on 25 September 2005. There was some surprise that this, the first meeting between the UN and LRA, was easy to arrange. General Paderi of the DRC army told the LRA that they needed to disarm as a prerequisite to future talks. Four days later, President Museveni declared that, if Congolese authorities did not disarm the LRA combatants, the UPDF would be sent across the border in pursuit. This sparked a diplomatic row between the governments of the DRC and Uganda, with both militaries making a show of force along their border, while the Congolese ambassador to the United Nations sent a letter to the UN Secretary-General demanding that an economic embargo be placed on Uganda in retaliation.
