Both teams have now won back-to-back games in the Classification Round for 13th to 16th place with Belgium following up their success over Poland by crushing hosts Romania 84-44.
It was an electrifying first half display by the Belgian team who hit their marks right from tip-off and were out of sight by half-time, as they moved 44-17 in front.
Antonia Delaere, who played for the senior national team during the EuroBasket Women Qualification Round earlier this summer led by example.
The guard accumulated 19 points, including three triples, while Axelle Bernard grabbed six offensive rebounds.
The Czech Republic kept Poland winless with a 63-52 victory and so while still perhaps too premature to call, it does look at this early stage to be shaping up as potentially a two-way fight with Belgium to achieve a precious Division A reprieve.
But it was far from straightforward for the Czechs who having dominated the first half 32-21, looked as if they might let their superiority slip and allow Poland back into the game after a poor third quarter.
However 16 points from forward Mariana Opocenska and a strong start to the final period helped them ease home.
