The Chinese pair of Xu Linyin and Wu Penggen looked poised to bounce back from their opening Pool C loss to Switzerland when they took the first set by eight points and then went toe-to-toe with the Germans in the second.
But it was Brink and Reckermann who took points at crucial moments to square the match, and when mistakes began to creep into the game of the Chinese duo in the decider, the Germans pulled away to their second win in as many matches.
Meanwhile, top seeds and reigning world champions Larissa Franca and Juliana Silva became the first women's team into the knockout phase of the competition at Horse Guards Parade with a comfortable win over Germany.
Larissa and Juliana conceded just 15 points in routing Mauritius in their first Pool A outing, and were again comprehensive in their victory today, outclassing Katrin Holtwick and Ilka Semmler 21-18 21-13.
The Germans, who beat the Czech Republic in their first match, will nevertheless fancy their chances of reaching the knockout phase, with their final preliminary match coming against minnows Mauritius on Wednesday morning.
