Double entry visa for Indian national

Hi,
I'm an Indian national resident(employed) in Dubai for about three years now. I am planning to join a tour group to DPRK in June and the itinerary requires me to be in Beijing before leaving for NK. The return journey from Pyongyang to Beijing is by train and hence would require double/multiple entry type. I have travelled to Oman, Bahrain, and Singapore in the last one year apart from India of course. Do you foresee any complication in me getting the double entry one?
