Multi - entry visa for china

For my work i am a lot in China .
I have lived in sweden for 10 years and have a Swedish residence permit.
If i apply(3 times now) for a multi visum in Stockholm with my dutch passport , I always get a 2 entry visum. My colleagues always get multi entry because the hold a Swedish passport. Why is there a difference, and is it maybe better to apply in Holland for the visum? The consulate told me it has to do with the agreement between Holland and China. But Holland also has multi entry visum to China!!

Thanks for your help,

Ralph
