could be a chest to hold Chinese gambling mother of pearl gaming counters, but that would be from the 1700s
the chest looks modern
another issue is that its stamped China, import item?
What's the box made of?

Not cloissone which has enamel fired in wire formed cells. It is really champleve where enamel is merely applied in a background of cast or repousse metal. Champleve is much cheaper than cloisonne to make and costs a lot less retail.
