听力原文： A new round of six-nation talks aimed at North Korea's nuclear disarmament will begin on July 26 in Beijing, the Chinese and South Korean foreign ministries announced Tuesday. Notably, no limit was apparently set for the length of talks, underscoring a strong push by the United States and the other nations involved in the negotiations--China, Russia, Japan and South Korea in addition to North Korea--to reach a breakthrough even if it means extending the talks beyond the 4-day limit generally adhered to during the three previous unsuccessful rounds. Which statement is NOT true about the new round of six-nation talks?
