a quick search on google comes up with "wenling jinma' who make melamine dinnerware. it says they were established in 2006 but i didn't find the same design, it was tricky to find any decent pics as they seem to do mostly export pieces. but yours seems kinda shiny, like enamel over metal? hmm.
edit - forgot to add, i think the first character says "zhong", but can't read the rest lol
