Copper Teapot with traditional Chinese floral design, only mark is CHINA on bottom of pot

I found this at an Estate Sale, it was only a dollar! It was so tarnished, but I got it home and started shining it. It is beautiful, the pot is copper and so is the lid, the single bail is copper and wood. It has a brass knob on lid, the only marking I can find on it is CHINA on the bottom. I am just wondering about the history of the item. If anyone has any info or suggestions on where to search please let me know!
