( CNN ) -- The second round of talks between North Korea and the U.S.-led U.N. Command on the peninsula ended Friday . The talks were designed to set the stage for higher-level discussions on the sinking of a South Korean warship , for which North Korea has been blamed . The two sides met for about an hour and 45 minutes , a spokesman with the U.N. Command told CNN . They agreed to hold another colonel-level meeting next Thursday . Friday 's was the second meeting between the two parties since the March attack on the Cheonan , which killed 46 South Korean sailors . An international investigation blamed North Korea for the sinking , an assertion the North has denied . Officers from both sides met in Panmunjom in the demilitarized zone between North and South Korea . The demilitarized zone was created as part of the armistice signed between the two Koreas in 1953 that halted fighting in the Korean War , but the war has never officially ended . The United Nations and North Korea began occasional meetings between generals -- `` general officer talks '' -- at Panmunjom in 1998 in an effort to lessen tensions . South Korea has said that an investigation concluded that a North Korean submarine fired a torpedo that sunk the South Korea warship . Earlier this month , the United Nations formally condemned the sinking of the Cheonan , but did not specifically name North Korea . `` The Security Council deplores the attack , '' the 15-member council said in what is known as a presidential statement . It urged that `` appropriate and peaceful measures be taken against those responsible for the incident aimed at the peaceful settlement of the issue . '' It also called for full adherence to the 1953 armistice agreement . At the Friday meeting , the U.N. Command proposed a joint group to assess any armistice violations in the warship 's sinking . The two sides adjourned after they agreed to develop specific proposals , the Command said .
