Shades of USA! I don't remember the whole story, but years ago, when the Japanese named a town "USA", (Made in USA) in a blatant attempt to deceive buyers, the United States was able to force them to cease and desist. One would think that with all the trade agreements these days, Murano could protect it's trademark better.
In the US, the McKinley Tariff Act of 1890 established (among other things) that all goods imported into the US must be marked with the country of origin. Then in 1914 (I think) the tariff act was amended to all goods must be marked "Made in XXX".
So in the case of the Japanese town named USA, the goods imported into the US would still need to be marked Made in JAPAN.
If you look at the label on the Murano piece posted
here by KevH, you will see that it is marked "Made in Murano ITALY" to comply with the US trade laws.
Going back to the Japanese town, the goods could have been marked "Made in USA JAPAN" but I can see how the US would have banned those goods because it would cause confusion to the American consumer and was also an attempt to misrepresent manufacturing origin of the good. (BTW - interesting story which I had not heard before and cannot confirm.)
Of course none of this applies if the item was not made for the US import market
