Another round of working-level meetings under the auspices of the six-party nuclear talks may convene later than expected, a Japanese daily reported Saturday. The Nihon Keizai, quoting a diplomatic source in Beijing, said the talks would likely be held after August not this month. The source said extra time would be needed for member nations to analyze and evaluate new proposals put forth by the U.S. and North Korea. The talks are aimed at resolving a nearly two-year-old dispute over North Korea's nuclear weapons program.
