Instruction:
Tell me which one of the following countries are in the European Union: The Netherlands, Switzerland, Germany, Finland, the United Kingdom, Italy, Luxembourg, Turkey, Australia, Vietnam, Canada.

Response:
The Netherlands, Germany, Finland, Italy and Luxembourg are in the European Union.

Rest of the countries: Switzerland, the United Kingdom, Turkey, Australia, Vietnam and Canada are not a part of the European Union but might have deals allowing them to benefit from the certain conveniences of the European Union such as free trade.

For example, while Switzerland has very close ties with European Union nations and has similar benefits, they are not a part of the EU. Switzerland enjoys benefits such as freedom of movement of people between the EU member states and Switzerland, this is due to a separate agreement: Agreement on the Free Movement of Persons (AFMP).
