The technique of many small cuts on the surface of the vase is called battuto, generally speaking the more cuts per square inch the higher the quality tends to be (more labour intensive). As far as I know it was first developed mid 20th century on Murano but since used elsewhere as well. In the past decade I have seen signed vases from Ichendorf (in TK Maxx) and labelled examples from India, safe to assume there are plenty from China as well.
I don't remember an example like yours though with a colour mostly cut away to reveal another colour underneath, somewhat like cameo glass. There are examples from Murano with two colours where one colour fades into the other but they are not like yours. I have one like that but have not been able to positively identify it yet, will try and get a photo later to illustrate.
