Well, the Czech Republic is a neighbouring country of Germany and is part of the European Union, so possible production there is subjected to the same quality-demands/standards as products made in Germany or any other EU-countries.
Though labour costs there (and also in European countries like Slovakia, Poland, Baltic states, ... and most certainly the poorest EU-memberstates Romenia and Bulgaria) are indeed still lower there then in Germany and other countries in the Western part of Europe.
