After encouragement by Richard Clarke, Clinton issued an executive order in July 1999 declaring the Taliban regime as a state sponsor of terrorism. This was followed in October 1999 by Resolution 1267 sponsored by the United States placing economic and travel sanctions on the Taliban. The Taliban, however, stood by bin Laden, and the United States, along with Russia, proposed yet another UN resolution (Resolution 1333), this time imposing an embargo an arms shipments to the Taliban. The move was meant to weaken the Taliban in their fight against the Northern Alliance in their civil strife. However, the resolution did little to limit the illegal flow of arms from Pakistan.
