WASHINGTON -- Russia, China and North Korea were all "key suppliers" of ballistic missile technology to countries developing weapons of mass destruction during the first six months of 2000, according to an intelligence report delivered to Congress this month.

The Central Intelligence Agency (CIA) is required by a 1997 law to submit the "Unclassified Report to Congress on the Acquisition of Technology Relating to Weapons of Mass Destruction and Advanced Conventional Munitions" every six months.

China also continued what the report called "substantial" assistance to Pakistan’s ballistic missile program during the first half of 2000.

Other countries that received help developing ballistic missiles during that period included India, Libya, Egypt and Syria, according to the report.
