Both teams took unassailable leads at the top of Groups A and C respectively.
The Serbians, the Olympic and reigning world champions, are hoping to win the World League for the fifth straight year and brushed aside Slovakia 11-2 at the Mladost Sports Center in Becej to finish on 17 points.
In the other match in Group A, Romania beat Germany 9-7 at the Steaua Bucharest Club indoor pool in the Romanian capital.
