The two sides have never competed in the premier annual women’s volleyball tournament and will be hoping to mimic Turkey’s brilliant debut in 2012 when they won bronze.
Bulgaria saw off 2011 World Grand Prix bronze medallists Serbia 3-1 (34-32, 25-22, 21-25, 25-20) in the first semifinal before the Czech Republic disposed of the Netherlands in four sets (25-17, 20-25, 25-23, 25-17) in the second match.
The result means there are just two European vacancies left for the international showcase, with a tournament set to be held later this year to decide them.
