Group I

The nine teams were first randomly divided into three pools of three teams to compete in round-robin competitions. The nine teams were then divided into three new pools based on their placing in their first pools, which would be used to determine each team's overall placing in the zonal group. The team that finished first overall would be promoted to the World Group II Play-offs, while the team that finished ninth would be relegated to Group II for 1999.
