China's relationship with Nk is strictly strategic in nature. What financial interests they do have is peanuts compared to their global trade. China has to strike a balance between being too hard or being too soft. They certainly do not want regime change the puts U.S. interests on their doorstep, nor do they want Nk refugees clogging up China's social order. Nk having a nuclear capability in such close proximity may make China more nervous than all of the above!
