Answer: No, the semicolon is used incorrectly.
Explanation: Semicolons are meant to be used when splitting two independent clauses that are closely related.
Example
Darling always loved apples; she used this as her thesis.
To her, the papaya tree symbolizes two things; Vietnam and herself.
Vietnam and herself is a dependent clause (if you made it into a sentence it would be a fragment), therefore cannot be paired with a semicolon.
