The term Asian refer to the continent of Asia or its people.
In the United Kingdom, the term may refer to people from South Asia (in particular Pakistan, India, Bangladesh, Sri Lanka, Afghanistan and Maldives)
Another term is Oriental, referring to the Orient ("the East"), and contrasted with Occidental and the Occident ("the West"). What regions are referred to vary. Today sometimes considered Eurocentric and therefore somewhat disparaging, despite not used as such.
