I just visited the Chinese shop and spoke to the owner. She had a number of very similar vases, large white loopings on a clear-to-blue or clear-to-pink background, smooth polished base and of impeccable quality and she confirmed that these are, in fact, Chinese. Other products from the same factory include square shapes in clear glass you'd swear were Krosno, and multicoloured long necked vases with fancy s-bends that are normally associated with the baltic states.
