Since last September, when I announced the measures being implemented today to ease sanctions against North Korea, North Korea has maintained its moratorium on missile tests. These measures are supported by our close allies in the region and are part of the process of close coordination between the United States, Japan, and South Korea recommended by former Secretary of Defense William Perry. We will continue to build on these efforts and on the recent North-South summit to achieve additional progress in addressing our common proliferation concerns.
