Terrorism was very much on the minds of trade ministers meeting this week in Doha, Qatar as they discussed a new round of global trade talks. Some were worried about personal safety: Many received security briefings from their national intelligence services on the possibility of a terror attack during the meeting. Many were also trying to reconcile a set of conflicting priorities created by the Sept. 11 attacks. The need to liberalize trade and open borders to economic opportunities is clashing with the imperatives of the international fight against terrorism. The dilemma is not insuperable. In fact, the conflicting demands can be reconciled, but it will take creative diplomacy to meet both objectives.
